Accupro CKS1610020MSC Keyless Drill Chuck 1/8 to 5/8 in

Product Description

The ACCUPRO CKS1610020MSC is a keyless drill chuck designed for threaded-mount applications requiring a secure, tool-free bit change. Built with a steel chuck body and ball bearing construction, it accepts round-shank tooling from 1/8 inch up to 5/8 inch. The 1/2-20 threaded mount is a standard interface found on a wide range of benchtop and handheld drill platforms. With a sleeve diameter of 52 millimeters and a closed length of approximately 4.13 inches, this chuck is sized for general-purpose drilling work in fabrication, maintenance, and production environments. Installation and service are typically performed by machinists, tool-and-die technicians, and industrial maintenance mechanics.

This chuck fits applications where quick bit changes and consistent grip across the full capacity range are priorities. The keyless design eliminates the need for a chuck key, making it practical for high-frequency tooling changes on drill presses, portable drills, and similar equipment. The ball bearing mechanism supports smooth operation and repeatable runout performance. It is suited for light to moderate-duty drilling in metal, wood, and plastic in both shop and field maintenance settings.

Installation Notes

Installation should be performed by a qualified machinist or maintenance mechanic. Disconnect and lock out all power to the drill before removing or installing a chuck. Inspect the spindle threads for damage or debris before threading on the new chuck, and confirm full thread engagement before operation. Do not use impact methods to seat the chuck that could damage spindle threads or bearing races.
