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—Round-shank adapters also fit into collets, so you can use them with rotary grinding tools.
Hex Shank—Hex-shank adapters also fit in power screwdrivers and other tools that accept a ¼" hex shank.
