Jacobs Hand-Tite 1/2 in. Keyless Drill Chuck 3/8-24 Mount 31037

The Jacobs Hand-Tite keyless drill chuck features a 1/2 in. maximum capacity and a 3/8-24 threaded mount, allowing it to convert any 3/8 in. drill into a 1/2 in. drill. Its split-bit jaw design provides higher gripping power than standard keyed chucks through high mechanical advantage that converts hand-tightening torque into superior bit-gripping force. Compatible with variable speed corded and cordless portable drills, it accepts bits from 1/16 in. to 1/2 in.
