0.8–10mm Keyless Drill Chuck Converter with 1/4-Inch Hex Shank Adapter

Fumbling with chuck keys, slipping drill bits, and switching back and forth between different power tools shouldn't slow down your woodworking, metalworking, or home improvement projects. Instantly transform your impact driver or hex-drive power tool into a versatile precision drill with our keyless drill chuck converter, engineered with a standard 3/8"-24UNF thread and a quick-change 1/4-inch hex shank.

Crafted from heavy-duty carbon steel and durable alloy materials, this keyless chuck features a 3-jaw design that adjusts smoothly from 0.8 mm up to 10 mm (approx. 1/32 in to 3/8 in). The textured outer grip allows effortless hand-tightening, securing round-shank twist bits, micro-drills, and countersinks without requiring a traditional chuck key. Included with a quick-release 1/4-inch hex shank adapter, this tool connects directly into standard impact drivers, cordless screwdrivers, and magnetic bit holders, giving you instant bit changes without swapping out tools.

Key Features

• Universal 0.8–10mm Clamping Range: 3-jaw precision chuck holds round, hex, and small-diameter drill bits tightly centered.

• Keyless Hand-Tightening Grip: Textured outer collar allows quick, tool-free bit changes directly by hand.

• Standard 3/8"-24UNF Threaded Mount: Precision-machined internal thread ensures a solid, wobble-free lock onto the shank adapter.
