Made from durable S2 steel with a black manganese phosphate coating, it offers enhanced torque absorption and longer lifespan, making it ideal for professional screwdriving, joinery, and assembly tasks. ## Description From the manufacturer Makita Impact Black Torsion Bits Introducing Makita Impact Black Torsion Bits; manufactured from S2 steel to provide exceptional durability and strength, with precision machined tips for better fit to make full contact with the screwhead for maximum power transfer, the Impact Black Torsion Bits are 20 per cent more durable than that of a standard screwbit, for a longer service life. The Impact Black Torsion Bits are coated in manganese phosphate for wear resistance and to prevent rusting and corrosion for longer life. Impact Black Torsion Bits absorb hard impacts when screwing screwbits or when placing the screwhead on the surface and the torsion zone counteracts high torque peaks. A screwguide helps to keep the screwbit perfectly positioned as they are driven into the material, ideal for fitting hinges. Impact Black Torsion Bits are suitable for various applications including screwdriving, cabinet makig, joinery, assembly, fixings and more.
