Accupro CKS1009020MSC Keyless Drill Chuck 3/8 in Threaded

Product Description

The ACCUPRO CKS1009020MSC is a keyless drill chuck designed for use with threaded-mount drilling equipment. It accepts bit shanks from 1/32 inch up to 3/8 inch capacity, making it suitable for a wide range of twist drills, step bits, and other round-shank tooling. The 3/8-24 threaded mount provides a standard connection to compatible spindles. Ball bearing construction supports smooth, consistent jaw movement during bit changes. The sleeve diameter measures 37 millimeters (approximately 1.46 inches), and the chuck is constructed from steel for durability in production and maintenance drilling applications. Installation and bit changes require no wrench or key.

This chuck is suited for use in light industrial, maintenance, and shop drilling operations where frequent bit changes are required. The keyless design speeds up tool changes on benchtop drill presses, handheld drills, and similar equipment with 3/8-24 threaded spindles. It is a practical replacement or upgrade option for trades and shop environments where downtime from tool changes needs to be minimized. Typical users include machinists, millwrights, maintenance technicians, and general fabrication professionals working with steel, aluminum, plastics, and similar materials.
