Accupro CPM1009000MSC Keyless Drill Chuck 3/8-24 Mount

Product Description

The ACCUPRO CPM1009000MSC is a keyless drill chuck designed for threaded-mount applications requiring precise bit retention across a wide grip range. It accepts round-shank drill bits from 1/32 inch up to 3/8 inch in diameter and mounts via a standard 3/8-24 threaded arbor. The chuck body is constructed from steel for durability under repeated use. A ball bearing mechanism supports smooth, consistent tightening without a key, reducing tool-change time on the bench or at the machine. The 41 mm sleeve diameter provides a solid grip surface. An M5 screw is included. This part is installed by machinists, tool-and-die technicians, and general shop mechanics.

The CPM1009000MSC suits bench-top drill presses, portable electric drills, and light CNC tooling spindles that use a 3/8-24 threaded mount interface. It is appropriate for residential shop use, light industrial environments, and trade applications where a compact, keyless chuck replacement or upgrade is needed. The closed length measures approximately 2.54 inches and the open length measures approximately 2.15 inches, keeping the overall spindle-to-tip distance compact for tight clearance work.

Installation Notes

Installation is performed by machinists or qualified shop technicians. Disconnect and lock out power to the drill press or tool before removing the existing chuck. Use the included M5 screw to secure the chuck to the threaded arbor, and verify the chuck runs true before returning the tool to service. Follow applicable shop safety procedures and manufacturer guidelines when servicing powered rotating equipment.
