Accupro CPM1310000MSC Keyless Drill Chuck 1/2-20 Mount

Product Description

The ACCUPRO CPM1310000MSC is a keyless drill chuck designed for threaded-mount spindles with a 1/2-20 thread. It accepts drill bits and round-shank tooling from 1/16 inch up to 1/2 inch capacity, covering the full range of common drill bit sizes used in metalworking, woodworking, and general fabrication. The chuck body is constructed from steel and uses a ball bearing mechanism for smooth, consistent jaw actuation. With a sleeve diameter of 43 millimeters and a closed length of approximately 2.93 inches, this chuck is sized for benchtop and handheld drill applications where a compact, reliable clamping solution is needed. An M6 screw is included for installation.

This chuck is suited for use on drill presses, handheld power drills, and similar rotating equipment with a 1/2-20 threaded spindle. It is appropriate for light industrial, maintenance, and shop applications across trades including machining, mechanical, and general construction. The keyless design allows for hand-tightening and quick bit changes without a chuck key, which is an advantage in production or service environments where speed and convenience matter.
