1/2-20UNF Keyless Drill Chuck & 1/2-Inch Adapter Set

Slipping drill bits, time-consuming manual key chuck changes, and restricted impact wrench functionality shouldn't slow down your woodworking or metalworking projects. Convert your 1/2-inch impact wrench into a versatile power drill instantly with our 1/2-20UNF keyless drill chuck and adapter set, engineered with a quick-grip ratcheting mechanism and a broad clamping capacity.
