Accupro CPX1009020MSC Keyless Drill Chuck 3/8-24 Mount

Product Description

The ACCUPRO CPX1009020MSC is a keyless drill chuck designed for threaded-mount installation on portable drills, drill presses, and compatible rotary tools. It accepts bit shanks from 1/32 inch up to 3/8 inch, making it suitable for a wide range of twist drills, step bits, and small-diameter tooling. The chuck uses a ball bearing design for smooth tightening and consistent concentricity under load. The sleeve diameter measures 41 millimeters, and the unit ships with an M5 mounting screw included. At 0.49 pounds, it is a compact, lightweight replacement or upgrade chuck for general-purpose drilling applications.

This chuck is suited for residential and light commercial maintenance environments where a reliable keyless chuck is needed on a 3/8-24 threaded spindle. Typical installations include benchtop drill presses, handheld electric drills, and similar rotary equipment used by HVAC technicians, electricians, plumbers, and general maintenance trades who need to swap bits quickly without a key.
