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-12005 is a 10 piece 25mm Impact Black bit set, with C-Form ¼” hex shank containing one each of the most popular bits PH1, PH2, PH3, PZ1, PZ2, PZ3, T15, T20 and T30 and a 60mm magnetic bit holder. The E-12005 bit set is supplied in a small and compact holder for added portability; easily stored and carried in a pocket and complete with keyring for convenient hanging and attachment. Bit sizes are printed on the holder for easier recognition.
