Accupro CKS1309020MSC Keyless Drill Chuck 1/2 in Threaded Mount

Product Description

The ACCUPRO CKS1309020MSC is a keyless drill chuck designed for threaded-mount installation on portable drills and drill presses. It accepts bits from 1/16 inch up to 1/2 inch capacity, making it suitable for a wide range of drilling applications across metal, wood, and composite materials. The chuck uses a ball bearing design for smooth, consistent tightening without a key. The steel construction delivers the durability required in production or jobsite environments. Sleeve diameter measures 40 millimeters, and closed length is approximately 3.27 inches, with an open length of approximately 2.99 inches. Licensed machinists, millwrights, and skilled tradespeople are the typical installers.

This chuck is well suited for residential and commercial trade applications where quick bit changes are a priority. The 3/8-24 threaded mount is a common spindle thread found on many corded and cordless drill platforms. It is appropriate for use in light manufacturing, maintenance and repair operations, HVAC equipment assembly, electrical panel fabrication setups, and general mechanical service work. The keyless design reduces downtime when cycling through multiple bit sizes on the job.

Installation Notes

Installation should be performed by a qualified machinist or mechanic familiar with drill spindle hardware. Disconnect or de-energize the drill or drill press before removing or installing the chuck. Thread the chuck clockwise onto the spindle until fully seated, and use the appropriate spindle lock or arbor block to secure the spindle while tightening. Do not overtighten using impact methods, as this may damage the spindle threads or chuck body.
