Safety Rules for Rotary Tools - (cont.)
Inspect your workpiece before cutting. When cutting irregularly shaped workpieces, plan your work so it will not slip and pinch the bit and be torn from your hand. For example, if carving wood, make sure there are no nails or foreign objects in the workpiece. Nails or foreign objects can cause the bit to jump. Never start the tool when the bit is engaged in the material. The bit cutting edge may grab the material causing loss of control of the cutter. Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control and kick-back. The direction of feed with the bit into the material when carving, routing or cutting is very important. Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the chips are thrown). Feeding the tool in the wrong direction, causes the cutting edge of the bit to climb out of the work and pull the tool in the direction of this feed. If the workpiece or bit becomes jammed or bogged down, turn the tool OFF by the switch. Wait for all moving parts to stop and unplug the tool, then work to free the jammed material. If the switch to the tool is left ON the tool could restart unexpectedly causing serious personal injury. Do not leave a running tool unattended, turn power off. Only when tool comes to a complete stop it is safe to put it down. Do not grind or sand near flammable materials. Sparks from the wheel could ignite these materials. Do not touch the bit or collet after use. After use the bit and collet are too hot to be touched by bare hands. Regularly clean the tool's air vents by compressed air. Excessive accumulation of powdered metal inside the motor housing may cause electrical failures. Do not allow familiarity gained from frequent use of your rotary tool to become commonplace. Always remember that a careless fraction of a second is sufficient to inflict severe injury. Do not alter or misuse tool. Any alteration or modification is a misuse and may result in serious personal injury. This product is not intended for use as a dental drill, in human or veterinary medical applications. Serious personal injury may result. When using the steel saws, cutoff wheels, high speed cutters or tungsten carbide cutters, always have the work securely clamped. Never attempt to hold the work with one hand while using any of these accessories. The reason is that these wheels will grab if they become slightly canted in the groove, and can kickback causing loss of control resulting in serious injury. Your second hand should be used to steady and guide the hand holding the tool. When a cutoff wheel grabs, the wheel itself usually breaks. When the steel saw, high speed cutters or tungsten carbide cutter grab, it may jump from the groove and you could lose control of the tool. Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

Rotary Tool and run the 415 Dressing Stone lightly against the revolving wheel point. This removes high spots and trues up the wheel point for good balance. The hanger is provided for the use of hanging your tool while using the flex-shaft or for storage. If you do not use the hanger, remove it from the tool and snap it back into place underneath the cord so it will be out of the way while the tool is in use. DREMEL KEYLESS CHUCK Use only with black chuck #4486. Other chucks may ! CAUTION not allow accessory bit to be tightened fully. The keyless chuck holds various accessories with shank sizes 1/32" to 1/8" and is intended for light duty accessories such as drill bits, sanding drums, polishing accessories, wire and bristle brushes and cut-off wheels. The keyless chuck allows you to change accessories frequently, quickly and easily. There are some applications which can generate high forces on the bit or if you are unable to generate finger tightening pressure sufficient to secure the bit you must use the supplied wrench to assist in securing the bit. Attaching the Keyless Chuck and Accessory Bit Read and understand the manual for use of the keyless chuck with the tool. ! WARNING Insert and securely tighten the shank of the accessory well within the jaws of the chuck. If an accessory is not properly gripped within the jaws of a chuck it may loosen and fly out during
Note: Some rotary tool kits may not include all four collets sizes. BALANCING ACCESSORIES For precision work, it is important that all accessories be in good balance (much the same as the tires on your automobile). To true up or balance an accessory, slightly loosen collet nut and give the accessory or collet a 1/4 turn. Retighten collet nut and run the Rotary Tool. You should be able to tell by the sound and feel if your accessory is running in balance. Continue adjusting in this fashion until best balance is achieved. To maintain balance on abrasive wheel points, before each use, with the wheel point secured in the collet, turn on the

use possibly striking you or bystanders. To replace or attach the keyless chuck accessory to your MultiPro rotary tool, unplug the tool and engage the shaft lock button then remove the collet and collet nut. Thread the keyless chuck on the end of the shaft. Engage the shaft lock button again, insert the accessory shank into the chuck and finger tighten until the shank is secure. For small size drill bits, close the chuck to the point where the bit will just fit in; then tighten securely. This helps center the bit in the keyless chuck correctly. In some high force applications such as removing metal, tile cutting or routing, the bit (tungsten carbide cutters, high speed cutters, router bits or tile cutters) and chuck will become hot if overloaded for extended periods of time. Overloading the chuck may cause the

Operating Instructions - (Cont.)

Using the Rotary Tool

The first step in learning to use the Rotary Tool is to get the feel of it. Hold it in your hand and feel its weight and balance. Feel the taper of the housing. This taper permits the Rotary Tool to be grasped much like a pen or pencil. The 395T6 Variable Speed tool has a unique comfort grip on the nose and back seating, which allows the user added comfort and control during use. You can feel the difference! Always hold the tool away from your face. Accessories can be damaged during handling, and can fly apart as they come up to speed. This is not common, but it does happen. Practice on scrap materials first to see how the Rotary Tool's high speed action performs. Keep in mind that the work is done by the speed of the tool and by the accessory in the collet. You should not lean on or push the tool during use. Instead, lower the spinning accessory lightly to the work and allow it to touch the point at which you want cutting (or sanding or etching, etc.) to begin. Concentrate on guiding the tool over the work using very little pressure from your hand. Allow the accessory to do the work. Usually, it is best to make a series of passes with the tool rather than attempt to do all the work in one pass. To make a cut, for example, pass the tool back and forth over the work, much as you would a small paint brush. Cut a little material on each pass until you reach the desired depth. For most work, the gentle touch is best. With it, you have the best control, are less likely to make errors, and will get the most efficient work out of the accessory.
Questions or Problems?Call 1-800-437-3635
or check our website at www.Dremel.com
For best control in close work, grip the Rotary Tool like a pencil between your thumb and forefinger.
The Golf Grip method of holding the tool is used for more aggressive operations such as grinding a flat surface or using cutoff wheels.

WARNING

Whenever you hold the tool, be careful not to cover the air vents with your hand. This blocks the air flow and causes the motor to overheat.

Operating Speeds

Set the speed indicator to fit the job; to achieve the best job results when working with different materials, the speed of the Rotary Tool should be regulated. Only a full wave output speed control such as the Dremel Model 221 should be used with the 275T6 Rotary Tool. To select the right speed for each job, use a practice piece of material. Vary speed to find the best speed for the accessory you are using and the job to be done. NOTE: Speed is affected by voltage changes. A reduced incoming voltage will slow the RPM of the tool, especially at the lowest setting. If your tool appears to be running slowly increase the speed setting accordingly. The tool may not start at switch position #1 in those areas where outlet voltage is less than 120 volts. Simply move the switch lever to a higher position to begin operation. There are three basic types of Rotary Tools: single speed, two-speed and variable speed models. On the single speed model, there is an ON-OFF switch. When the switch is on, the tool runs at 35,000 RPM. On the two-speed model, there is a LO and HI switch. When the switch indicator is on the low setting, the tool runs at about 15,000 RPM. When the switch indicator is on the high setting, the tool runs at about 35,000 RPM. On the variable speed model, there are switch setting indicators marked with a line. Slide to the number on the housing to select the operating speed needed from 5,000 35,000 RPM. You can refer to the charts on page 24, 25, and 26 to determine the proper speed, based on the material being worked and the type of accessory being used. These charts enable you to select both the correct accessory and the optimum speed at a glance. If you have a single-speed or two-speed model, you will be able to use many accessories to do a wide assortment of jobs. For the majority of applications, all models of the Rotary Tool should be used at top speed. Needs for Slower Speeds Certain materials, however, (some plastics and precious metals, for example) require a relatively slow speed because at high speed the friction of the accessory generates heat and may cause damage to the material. Slow speeds (15,000 RPM or less) usually are best for polishing operations employing the felt polishing accessories. They may also be best for working on delicate projects as eggery work, delicate wood carving and fragile model parts. (All brushing applications require lower speeds to avoid wire discharge from the holder.) No greater than speed setting 4 for the model 395-T6. Higher speeds are better for carving, cutting, routing, shaping, cutting dadoes or rabbets in wood. Hardwoods, metals and glass require high speed operation, and drilling should also be done at high speeds. The speed of Rotary Tool is controlled by setting this indicator on the housing.

Operating Speeds - (Cont.)
If you need it, single-speed models also can have speed control by using a Model 221 foot control unit. Not for use with variable speed or two speed models 285 or 395. Use with external speed control will damage the variable/two speed electronics.
Ultimately, the best way to determine the correct speed for work on any material is to practice for a few minutes on a piece of scrap, even after referring to the chart. You can quickly learn that a slower or faster speed is more effective just by observing what happens as you make a pass or two at different speeds. When working with plastic, for example, start at a slow rate of speed and increase the speed until you observe that the plastic is melting at the point of contact. Then reduce the speed slightly to get the optimum working speed. Some rules of thumb in regard to speed: 1. Plastic and other materials that melt at low temperatures should be cut at low speeds. 2. Polishing, buffing and cleaning with a wire brush must be done at speeds not greater than 15,000 RPM to prevent damage to the brush. 3. Wood should be cut at high speed. 4. Iron or steel should be cut at high speed. If a high speed steel cutter starts to chatter this normally means it is running too slow. 5. Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds, depending on the type of cutting being done. Use paraffin or other suitable lubricant on the cutter to prevent the cut material from adhering to the cutter teeth. Increasing the pressure on the tool is not the answer when it is not performing as you think it should. Perhaps you should be using a different accessory, and perhaps an adjustment in speed would solve the problem. Leaning on the tool does not help. Let speed do the work!
The point to remember is this: You can do the great majority of work with the single speed at its regular speed of 35,000 RPM. But for certain materials and types of work, you need slower speeds which is the reason the variable speed models and the speed control units are available. To aid you in determining the optimum operational speed for different materials and different accessories, we have constructed a series of tables that appear on page 24, 25 and 26. By referring to these tables, you can discover the recommended speeds for each type of accessory. Look these tables over and become familiar with them.

Assembly & Operation of Attachments

Not for use with router bits. Use with router bits will cause
INSTALLATION INSTRUCTIONS It is extremely important to carefully read and follow the directions to assemble the flex-shaft to your rotary tool below to ensure the tool will function properly. Attention: For optimum performance, allow your new flex shaft attachment to run at high speed on your rotary tool in a vertical position for 2 minutes before use. To properly attach the flex-shaft to the rotary tool, THREE items must be removed from the tool: the housing cap, collet nut and collet. Step 1. Press the Shaft lock button, unscrew and remove the collet nut.

Page 13

STEP 2

STEP 3

OPERATING INSTRUCTIONS Disengagement of the Flex-Shaft The flexible shaft may become disengaged if the motor of your rotary tool is not elevated higher than the working end of the flex-shaft. The #2222 Rotary Tool Stand is recommended to hold the rotary tool at the proper height. Collet and Accessory Assembly The collet assembly consists of a collet nut and collet. Take the collet nut and collet that were removed from your tool in step 2 and 3 and insert them into the tip of the flex-shaft handpiece.
Step 2. Unscrew the housing cap from the tool. Step 3. Remove the collet. Note: If the collet nut and collet are not removed from the motor shaft, the tool will not function properly.

STEP 4

Insert an accessory or bit as deeply as possible to avoid wobble during use. With the shaft lock button engaged on the flex-shaft handpiece retighten the collet nut. Step 4. Install the driver cap on the motor shaft and tighten. To prevent damage to tool, do not overtighten driver cap. Tighten the driver cap finger tight and then tighten an additional 1/3 turn with the wrench. (Wrench included with your rotary tool kit)

STEP 5

Collet Removal and Replacement Four different size collets to accommodate different shank sizes, are sold separately for your flex-shaft. To install a different collet, remove the collet nut and remove the old collet. Insert the unslotted end of the collet in the hole in the end of the flex-shaft. Replace collet nut on the shaft. Always use the collet which matches the shank size of the accessory you plan to use. Never force a larger diameter shank into a collet. FLEXIBLE SHAFT LUBRICATION The flexible shaft should be lubricated after every 25-30 hours of use. To lubricate, unscrew the flexible shaft assembly from the motor housing. Pull the center core out of the flexible shaft assembly. Wipe a very thin film of a good quality, high temperature grease on to the center core. To prevent damage to tool do not over grease shaft. Too much grease will cause the unit to overheat. Dremel shaft lubricant No. 5990952 or automotive wheel bearing grease should be used.

Step 5. Attach by screwing the collar of the flex-shaft to the rotary tool. Make sure the square end of the center core engages the square hole socket in the driver cap. Do not pull out center core to engage into driver cap. This could cause disengagement of center core from handpiece. If tool stops when shaft is bent, center core may be lodged in driver cap. Loosen shaft and remove core from driver cap. Then screw flexible shaft onto rotary tool housing again.
Reattach the flex-shaft to the rotary tool.

For use on wall tile, cement board and plaster When inserting the #562 bit into your MultiPro tool, it is very important that 1/16-1/8 of smooth shank remains visible above the collet. When using #562, Tile Cutting Bit, start the bit into the material at a 45 degree angle and then slowly bring it to a 90 degree angle to begin the cut. NOT FOR USE ON FLOOR TILE

Page 15

The #568 grout removal attachment comes completely assembled and ready to use. Use the #569 (1/16") bit for tiles spaced more than 1/16" apart. If your tiles are spaced more than 1/8" apart, it is recommended that you use the #570 (1/8") bit. Note: If the bit is too wide for the spacing between your tiles, you may damage your tile or the grout removal bit.
Step 1: Remove the housing cap from the tool. Step 2: Insert the grout removal bit into your rotary tool. When inserting the #569 or #570 grout removal bit into your Dremel rotary tool, be sure that the bit is secure within the jaws of the collet. Use the wrench to tighten the collet nut to prevent the bit from loosening within the collet. Do not use your Dremel Chuck, #4486, with the grout removal bits.
Step 3: Screw the grout removal attachment onto the rotary tool. Step 4: Adjust the attachment and bit to the desired cutting depth. Grout Removal Attachment Cutting Depth Adjustment The Multi Slide Depth Adjustment has increment markings of 1/8" (3,2 mm). These markings are for reference only in identifying the depth of your desired cut. The multiple channels of the depth adjustment let you choose the orientation of the attachment to the tool. Be sure to securely tighten the screw within one of the multiple channel positions. To set cutting depth: Cleaning Grout: Do not remove grout more than 1/8" below the face surface of the tile. Adjust the Multi Slide Depth Adjustment and bit so that no more than 1/8" of the bit extends beyond the base of the attachment.

1/8" 3,2mm

Removing Grout to Replace A Broken Tile: Remove all of the grout surrounding the broken tile. Adjust the Multi Slide Depth Adjustment so that no more than 1/8" of the bit extends beyond the base of the attachment. See Figure 5. Remove grout at a depth no more than 1/8" at a time. You may need to adjust the Multi Slide Depth Adjustment by 1/8" increments (reference the 1/8" incremental white markings on the Multi Slide Depth Adjustment) and make several passes until all the grout is removed. When removing grout deeper into the grout line, you may strike hidden objects like screw heads, mortar, tile cement or nails that may cause the bit to bind, overheat or break. Reduce the tool speed and work through it slowly, making several passes. In case of screws or nails, remove the grout around the area as the bit will not cut through them.

After removing 1/8" of grout, regrout to tile level. Seal the new grout.

Page 16

Operating Instructions Always pull the tool toward you! ! WARNING Do not push it! Pushing the bit may cause it to break. Hold the tool in a golf grip with the tool positioned below the attachment and the bit pointing upwards. On your variable speed tool, recommended tool speed is 15,000-20,000 RPM's or speed setting 6 to avoid damage to the bit. On your two speed tool, recommended tool speed is "Low" to avoid damage to the bit. Do not force the bit or put pressure on the back of the tool to remove the grout. Let the speed of the rotating bit do the work. Wear eye protection and dust mask. Inspect bit for damage. When bit is installed, always run it at no-load speed of the tool for one minute, as a damaged bit will break apart. Do not stand in front of or in line with bit.
Always use the tool with the depth guide positioned flat against the material being cut. The guide securely positioned on the material improves stability and control of your tool. The direction of feed with the bit into the grout is important. Always drag or pull the bit through the grout line. The grout bit is not intended for "plowing" through the grout and feeding the tool in the wrong direction will cause the bit to climb out of the work possibly damaging the bit and/or causing loss of control.

Before you begin, remove the black protective cap on your attachment. If cap does not slide off easily, insert the shank portion of any accessory through the housing opening of the attachment to hold shaft from rotating. Then twist off. Figure 1. Do not use the rotary tool shaft lock button when changing accessories on the attachment. Internal damage to the attachment may occur.
Screw the attachment onto your rotary tool. Hand tighten only. Reassemble the collet and the collet nut from step 2, on to the output shaft of the attachment. Figure 4. The right angle attachment can be oriented on your rotary tool in 12 different positions. The attachment should be positioned so the on/off speed control switch is easy to access. To reposition, unscrew the collar from the attachment until disengaged. Slide the attachment off. Then, reposition, slide the attachment back on the tool and retighten the collar. Figure 5. To change an accessory, insert the shank portion of any accessory (3,2 mm recommended) through the housing opening of the attachment to hold the shaft from rotating. With the shaft secured, loosen the collet nut and insert an accessory as deeply as possible to avoid wobble during use. You may need to pull back the shank from the housing opening to provide clearance while inserting the accessory. Figure 6.

Dremel Accessories
Use only Dremel Tested, High Performance Accessories. Other accessories are not designed for this tool and may lead to personal injury or property damage. The number and variety of accessories for the Rotary Tool are almost limitless. There is a category suited to almost any job you might have to do and a variety of sizes and shapes within each category which enables you to get the perfect accessory for every need. Refer to the DREMEL ACCESSORY ORDER FORM for illustrations of the accessories available. These accessories may be found at your local hardware, hobby or home center dealers.

Tungsten Carbide Cutters

These are tough, long-lived cutters for use on hardened steel, fired ceramics and other very hard materials. They can be used for engraving on tools and garden equipment. 1/8" shanks.

Engraving Cutters

This group has a wide variety of sizes and shapes, and are made for intricate work on ceramics (greenware), wood carvings, jewelry and scrimshaw. They often are used in making complicated printed circuit boards. They should not be used on steel and other very hard materials but are excellent on wood, plastic and soft metals. 3/32" shank.

Collets

If you expect to use a variety of accessories, we recommend that in the beginning you purchase a complete set of four collets. Store these so that you will have the proper size of collet for any accessory or drill bit you want to use. Currently, the 1/8", 3/32",1/32" and 1/16" collets accommodate all of the available Dremel accessories. 1/8" collets are included in most rotary tool kits.

Mandrels

A mandrel is a shank with a threaded or screw head, which are required when you use polishing accessories, cutting wheels, sanding discs, and polishing points. The reason mandrels are used is that sanding discs, cutting wheels and similar accessories must be replaced frequently. The mandrel is a permanent shank, allowing you to replace only the worn head when necessary, thus saving the expense of replacing the shaft each time.
Structured Tooth Tungsten Carbide Cutters
Fast cutting, needle-sharp teeth for greater material removal with minimum loading. Use on fiberglass, wood, plastic, epoxy and rubber. 1/8" and 1/4" shank.
Aluminum Oxide Grinding Stones (red/brown)
Round, pointed, flat you name the shape and there is one available in this category. These are made of aluminum oxide and cover virtually every possible kind of grinding application. Use them for sharpening lawn mower blades, screwdriver tips, knives, scissors, chisels and other cutting tools. Use to remove flash from metal castings, deburring any metal after cutting, smoothing welded joints, grinding off rivets and removing rust. These grinding stones can be resharped with a dressing stone. In machine shops, high speed drills and cutters normally are ground with aluminum oxide wheels. 1/8" shank.
Screw Mandrel No. 401 This is a screw mandrel used with the felt polishing tip and felt polishing wheels. 1/8" shank.
Small Screw Mandrel No. 402 This is a mandrel with a small screw at its tip, and is used with emery and fiberglass cutting wheels, sanding discs and polishing wheels. 1/8" shank.
Threaded Tip Mandrel No. 424 This is a mandrel with a threaded tip which threads into the polishing point accessory No. 427. 1/8" shank.
Silicon Carbide Grinding Stones (blue/green)
Tougher than aluminum oxide points, these are made especially for use on hard materials such as glass and ceramics. Typical uses might be the removal of stilt marks and excess glaze on ceramics and engraving on glass. 1/8" shank.

High Speed Cutters

Available in many shapes, high speed cutters are used in carving, cutting and slotting in wood, plastics and soft metals such as aluminum, copper and brass. These are the accessories to use for freehand routing or carving in wood or plastic, and for precision cutting. Made of high quality steel. 1/8" shank.

Diamond Wheel Points

Excellent for fine detail work on wood, jade, ceramic, glass and other hard material. Bits are covered with diamond particles. 3/32" shanks.

Page 21

Wire Brushes
Three different shapes of wire brushes are available. Never use wire brushes at speeds greater than 15,000 RPM. Refer to Operating Speeds section for proper tool speed setting. The three shapes come in three different materials: stainless steel, brass and carbon wire. The stainless steel perform well on pewter, aluminum, stainless steel, and other metals, without leaving "after-rust". Brass brushes are non sparking, and softer than steel; making them good for use on soft metal like gold, cooper and brass. The carbon wire brushes are good for general purpose cleaning.

Polishing Accessories

These include an impregnated polishing point and an impregnated polishing wheel for bringing metal surfaces to smooth finish; a felt polishing tip and felt polishing wheel, and cloth polishing wheel, all used for polishing plastics, metals, jewelry and small parts. Also included in this group is a polishing compound (No. 421) for use with the felt and cloth polishers. Polishing points make a very smooth surface, but a high luster is obtained using felt or cloth wheels and polishing compound. For best results polishing accessories should be used at speeds not greater than 15,000 RPM. Refer to Operating Speeds section for proper tool speed setting. No polishing compound is needed when using the 425 Polishing Wheel or 427 Polishing point.

Bristle Brushes

These are excellent cleaning tools on silverware, jewelry and antiques. The three shapes make it possible to get into tight corners and other difficult places. Bristle brushes can be used with polishing compound for faster cleaning or polishing.
Aluminum Oxide Abrasive Wheels Brushing Pressure
1. Remember, the tips of a wire brush do the work. Operate the brush with the lightest pressure so only the tips of the wire come in contact with the work. 2. If heavier pressures are used, the wires will be overstressed, resulting in a wiping action; and if this is continued, the life of the brush will be shortened due to wire fatigue. 3. Apply the brush to the work in such a way that as much of the brush face as possible is in full contact with the work. Applying the side or edge of the brush to the work will result in wire breakage and shortened brush life.
CORRECT: Wire tips doing the work.
Use to remove paint, deburr metal, polish stainless steel and other metals. Available in fine and medium grits. 1/8" shank.

Sanding Accessories

Sanding discs in fine, medium and coarse grades are made to fit mandrel No. 402. They can be used for nearly any small sanding job you might have, from model making to fine furniture finishing. In addition, there is the drum sander, a tiny drum which fits into the Rotary Tool and makes it possible to shape wood, smooth fiberglass, sand inside curves and other difficult places, and other sanding jobs. You replace the sanding bands on the drum as they become worn and lose their grit. Bands come in fine and coarse grades. Flapwheels grind and polish flat or contoured surfaces. They are used most effectively as a finishing sander after heavier surface sanding and material removal is completed. Flapwheels come in fine and coarse grades. Buffs are a great finishing accessory for cleaning and light sanding. They work effectively on metal, glass, wood, aluminum and plastics. Coarse and medium buffs are sold together. 1/8" shank.

INCORRECT: Excessive pressure can cause wire breakage.

Grinding Wheel

Use for deburring, removing rust, and general purpose grinding. Use with Mandrel #402.

Cutting Wheels

These thin discs of emery or fiberglass are used for slicing, cutting off and similar operations. Use them for cutting off frozen bolt heads and nuts, or to reslot a screw head which has become so damaged that the screwdriver wont work in it. Fine for cutting BX cable, small rods, tubing, cable and cutting rectangular holes in sheet metal.

Spiral Cutting Bit

Cuts through all types of wood and wood composites.

Drywall Cutting Bit

High Speed Router Bits For routing, inlaying, and mortising in wood and other soft materials. Use only with Dremel No. 330 Router attachment or No. 231 Shaper/Router table.

Page 23

Mandrel No. 401 is used with the felt polishing tip and wheels. Thread the tip on to the screw carefully. The felt tip must thread down straight on the screw Mandrel, and be turned all the way to the collar.
Mandrel No. 402 has a small screw at its tip, and is used with emery cutting wheels and sanding discs. Higher speeds, usually maximum, are best for most work, including cutting steel. Which is shown here.
The machine-screw threading on Mandrel No. 424 threads into polishing point No. 427. This and other threaded mandrels must be screwed firmly down to the collar before being used.
To replace a band on the Drum Sander, loosen the screw without removing it to contract the drum then slide the old band off. Slide the new sanding band on and then expand the drum by tightening the screw once again. Before each use, check to make certain that all components are assembled to accessory shank and that the drum is sufficiently expanded to secure the band during use. If sanding band is loose on the drum during operation it may fly off and strike you or bystanders.
