Diablo 3-1/2 in. #2 Square Drive Bits
Two #2 square drive (SQ2) power bits, 3-1/2 in. long on a 1/4 in. hex shank. The optimized tip grips the recess to reduce wear, stripping and slippage, and Diablo's MaxTorque Zone absorbs torque so the tip takes less stress when driving and removing screws. The bits are rated Impact Strong for impact drivers and drill drivers, and Diablo claims up to 50X longer life than standard bits.
