Makita is the leading manufacturer of professional power tools on the market. Introducing Makita Impact Black Bits; manufactured from S2 steel to provide exceptional durability and strength, with precision machined tips for better fit to make full contact with the screw head for a maximum power transfer, the Impact Black bits are 20 per cent more durable than that of a standard screw bit, for a longer service life. The Impact Black Bits are manufactured using a special hardening procedure; coated in manganese phosphate for wear resistance and to prevent rusting and corrosion for a longer service life. Impact Black bits absorb hard impacts when screwing screws or when placing the screw head on the surface and the torsion zone counteracts high torque peaks. The E-15768 is a 6 piece E-Form Impact Black nutsetter set, highly durable with anti-rust coating and equipped with ¼” hex shank. The E-15768 contains 50mm length socket sizes 6mm, 7mm, 8mm, 10mm, 12mm and 13mm, supplied in a clear case to allow the user to view the contents.
