Small-Hole Drill Chuck Adapters
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.

Keyless Drill Chucks with Integral Arbor
The integral arbor is more rigid for greater accuracy than a drill chuck used with a separate arbor.
R8 taper spindles are often found on manual milling machines.
Also Available: Replacement hoods, ball bearing sets, collars, jaws sets, jaw guides, shells, and drive pins. Select 30075A6 and specify replacement part and Albrecht model number.

Drill Chucks with NMTB Taper Integral Arbor
Limit runout and slippage under heavy cutting forces from manual mills and older CNC mills. These chucks have an integrated arbor for a one-piece design that makes them more accurate and compact than chucks with a separate arbor. Made of hardened steel, they resist wear from repeated use. Their shank is precision ground to the industry standard AT3 tolerance for a tight fit in your spindle. They meet ANSI standards for compatibility across machines with NMTB spindles. They're also compatible with older Erickson quick-change spindles. Internal threads in the shank connect to your machine's drawbar.
Twist the sleeve by hand to swap bits out quickly. The grip on the bit tightens as torque increases.
To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.
