Accupro CPX1310030MSC Keyless Drill Chuck 1/2-20 Mount

Product Description

The ACCUPRO CPX1310030MSC is a keyless drill chuck designed for threaded-mount installation on portable drills and drill presses used in metalworking, woodworking, and general fabrication. It accepts bit shanks from 1/16 inch up to 1/2 inch, making it suitable for a wide range of twist drills, step bits, and rotary accessories. The chuck uses a ball-bearing design for smooth, consistent tightening without a key. The 42 mm sleeve diameter and 1/2-20 threaded mount are standard dimensions compatible with common benchtop and handheld drill platforms. An M6 screw is included for secure installation. This chuck is typically installed by machinists, maintenance technicians, and tool-repair professionals.

This keyless drill chuck fits applications where fast bit changes and reliable clamping force are priorities. The 1/2-20 threaded mount is a common standard found on many benchtop drill presses and corded handheld drills used in light industrial and trade settings. The ball-bearing mechanism supports repeated use under moderate-duty drilling conditions. The steel construction provides durability for shop environments. Closed length is approximately 2.95 inches and open length is approximately 2.56 inches, making it a compact choice for space-limited setups.

Installation Notes

Installation is performed by machinists or maintenance technicians. Power down and disconnect or de-energize the drill before removing or installing the chuck. The included M6 screw typically threads into the spindle bore to secure the chuck against reverse rotation — confirm correct screw direction before tightening. Use appropriate spindle wrenches to remove the existing chuck and seat the replacement squarely on the threaded spindle before final torquing.
