Description 1Exquisite Craftsmanship: This hex drive bit is made from S2 alloy steel and has undergone a superb heat treatment process which has resulted in a significant increase in hardness, bending resistance and wear resistance. 2Impact Resistance: This hex drive bit is designed with a fine slim waist to resist strong impacts. The slim waist buffer absorbs strong impacts from the impact driver, thus giving the bit excellent impact resistance. 3Strong Magnetic Bit: This hex drive bit increases efficiency with a strong magnetic bit, with an overall magnetic treatment and an overall magnetic treatment of the bit to firmly attach the screw during use. 4Anti Slip: This hex drive bit is high torsion, high hardness, wear resistant, not easy to rust, strong magnetic anti slip, no more slipping, for strong impact and high strength screwdriving work suitable for screwdrivers, especially impact screwdrivers 5Wide Application: This hex drive bit is widely used for furniture repair, car repair, assembly parts disassembly, electrician repair, electrical repair, engineering repair, and also for all kinds of electric drills, electric screwdrivers and electric drivers.
