Driving 3-inch screws or bolt-in hardware with a standard drill bit that keeps walking off the mark, slipping in the chuck, or snapping under repeated impact — an impact-rated bit is built for the torque and percussive force that kills regular drill bits. 13/64-inch HSS impact-rated drill bit with 1/4-inch hex shank. Designed for use in impact drivers — the metallurgy and geometry handle percussive rotational force without the bit walking, slipping, or fracturing.Compact length keeps the bit controlled in tight spaces and reduces flex under torque. 118-degree conventional point starts cleanly in most metals without a center punch. Standard in the bit holders of framing crews, deck builders, and metal framing contractors across northeast Nebraska and northwest Iowa — the impact bit that doe Stocked at Crofton Lumber and Akron Lumber.
