The Bahco 66IM/10C-1 Heavy-Duty Torsion Bit Set contains a selection of impact bits suitable for impact drivers. These bits are designed for long-term use, with a torsion zone that effectively spreads strength concentration, absorbing torque peaks to avoid premature wear and tear and improve service life. All bits are made from high-performance alloy steel with a manganese phosphate finish and conform to DIN 3126, ISO 1173, style E 6.3. The set is supplied on a soft plastic holder with a safety lock belt clip. It includes: 3 x 50mm Phillips Bits (PH2 x2, PH3), 3 x 50mm Pozidriv Bits (PZ2 x2, PZ3), and 4 x 50mm TORX® Bits (TX20, TX25 x2, TX30).
