Accupro PNI0709100MSC Keyless Drill Chuck 3/8-24 Threaded Mount

Product Description

The ACCUPRO PNI0709100MSC is a keyless drill chuck designed for use with threaded spindle drives in portable and bench-mounted drilling applications. It accepts bit shanks from 0.012 to 0.291 inches, covering a wide range of twist drills, step bits, and driver accessories. The chuck uses a 3/8-24 threaded mount for secure spindle attachment and incorporates a ball bearing design for smooth, consistent tightening without a key. The stainless steel chuck body resists corrosion in shop environments. Sleeve diameter measures 30 millimeters. Closed length is approximately 2.47 inches and open length is approximately 2.20 inches. This unit weighs 0.63 pounds and ships as a single piece.

This keyless chuck is suited for residential and light commercial trade work, including use by electricians, plumbers, and HVAC technicians who operate cordless or corded drills with a 3/8-24 spindle thread. It fits standard drill press spindles and handheld drill motors that use this threaded interface. The keyless collar allows single-hand bit changes in the field, which reduces downtime during repetitive drilling tasks such as wire fishing, pipe penetrations, and bracket mounting.

Installation Notes

Installation is performed by a qualified technician familiar with rotating tool hardware. Power off and unplug the drill or drill press before removing the existing chuck or installing this unit. Thread the chuck onto the spindle by hand first, then tighten firmly in the direction of normal drill rotation to prevent self-loosening during use. Inspect the spindle threads for damage or debris before installation.
