Superiority of chip saw blade over abrasive cut off wheel 1.Faster than abrasive cut off wheel in cutting work. 2.Fine cutting section, and saving the time for after-treatment. Available also for cutting plastic pipe without burning of cutting section. 3.Lower frequency of blade change. Consequency the chip saw brings you the saving for working time. 4.Few spark springs. 5.No smell of the burning materials painted on the tools, like as abrasive cut off wheels. 6.Few chips springs from the materials. Consequently the chip saws brings you clean working plase. 7.Much more tough than abrasive cut off wheels, which shows as per the following diagram.
