10/13/16mm Drill Chuck Socket Adapter Hex Drill Chuck Converter Impact Wrench

The chuck size refers to the maximum bit shank diameter the chuck can grip. Most household cordless drills use a 10 mm or 13 mm chuck. Bench drill presses and larger corded drills commonly use 13 mm or 16 mm. Heavy-duty industrial drill presses may require a 20 mm chuck. Check the label on your existing chuck or the drill's manual to confirm the capacity before ordering.

A Manual Chuck (keyed chuck) uses a toothed chuck key to tighten and loosen the jaws around the bit. This provides a very firm grip and is preferred for heavy drilling. An Auto Chuck (keyless chuck) tightens by hand-twisting the collar — no key required — making bit changes faster. Auto chucks are popular for general-purpose drilling where speed of change matters more than maximum clamping force.

Arbors are adapter shanks that connect a drill chuck to a drill spindle or to accessories like hole saws and Forstner bits. Round Shank Arbors fit into standard drill chucks. Square Shank Arbors are used with brace drills or certain bench drill spindles. Hex Shank Arbors fit into quick-change hex collets and impact drivers. Choose the shank style that matches your drill's collet or chuck type.

The Wrench Converter variants (10 mm and 13 mm) are specifically designed to mount a standard drill chuck onto an impact wrench spindle, allowing the wrench to accept regular drill bits. Compatibility depends on the spindle thread of your specific impact wrench model. If you are unsure of your wrench's spindle thread specification, contact us to confirm before ordering.

These adapters are compatible with both wood and metal drilling applications. The chuck itself does not limit the material — what matters is using the correct drill bit type (HSS for metal, brad-point or spade for wood) and running the drill at an appropriate speed. For heavy-duty metal drilling, the keyed Manual Chuck variants are recommended for their stronger bit retention under higher torque loads.

Typically, you remove the existing chuck by unscrewing the retaining screw inside the chuck jaws (left-hand thread — turn clockwise to loosen), then unscrew the chuck from the spindle (counter-clockwise). Thread the new chuck adapter onto the spindle clockwise until snug, then reinstall the retaining screw. Exact steps vary by drill model — consult your drill's manual for model-specific instructions. If your drill uses a Jacobs taper mount rather than a threaded spindle, contact us to confirm compatibility.

Yes. Chuck Keys are available as a standalone variant in 10 mm, 13 mm, and 16 mm sizes, sold in 1, 2, or 5-piece packs. Select the key size that matches your chuck's key port diameter. Using the correct key size ensures full engagement with the chuck's gear ring and prevents rounding of the key teeth.
