Small-Hole Drill Chuck Adapters
Adapter Shown Installed
Round Shank
Hex Shank
Adapt your tools to hold wire-gauge drill bits, so you can drill small, precise holes. A knurled sleeve gives you the grip you need to tighten the jaws around the bit.
All adapters can be used with drill presses and hand-held power drills. Round-shank adapters also fit into collets, so you can use them with rotary grinding tools. Hex-shank adapters also fit in power screwdrivers and other tools that accept a 1/4" hex shank.
