Accupro CKS1310020MSC Keyless Drill Chuck 1/2-20 Mount

Product Description

The ACCUPRO CKS1310020MSC is a keyless drill chuck designed for use with threaded-mount drill spindles. It accepts bit shanks from 1/16 inch up to 1/2 inch in diameter and features a 1/2-20 threaded mount for secure spindle attachment. The chuck uses a ball-bearing design for smooth, consistent tightening without a key. The steel construction provides durability in demanding shop and field environments. This chuck is installed by machinists, tool-and-die technicians, and general maintenance trades working with benchtop or handheld drilling equipment.

This keyless chuck is suited for residential, commercial, and industrial applications where fast bit changes are needed without a chuck key. The 1/2-20 threaded mount is a common standard found on many benchtop drill presses and portable drills. The 40-millimeter sleeve diameter and compact closed length make it compatible with a range of drilling setups where clearance and weight are considerations.

Installation Notes

Installation is performed by machinists or qualified maintenance technicians. Always power down and lock out the drill press or disconnect the portable drill before removing or installing a chuck. Thread the chuck onto the spindle by hand first to avoid cross-threading, then tighten securely per the equipment manufacturer's guidance. Inspect the spindle threads for wear or damage before installing a new chuck.
