This Exchange-A-Blade torsion impact bit is made to last longer than standard impact bits. It is constructed out of tempered S2 spring steel, so that the torsion zone absorbs and dampens the stresses produced by modern impact drivers. With its powder-coated finish that won't damage the impact mechanism, the bit is corrosion resistant. The hex shank ensures the torsion bit fits with most modern impact guns, and the colour-coded band allows you to easily identify the size. They can be recycled for an environmentally friendly design.
