Accupro CPL1310000MSC Drill Chuck Keyless 1/2-20

Product Description

The ACCUPRO CPL1310000MSC is a keyless drill chuck designed for threaded-mount installation on drills and drill presses used in machining, fabrication, and general shop work. It accepts bit shanks from 1/16 inch up to 1/2 inch, covering the full range of common twist drills, step bits, and accessories. The 1/2-20 threaded mount is the standard spindle thread found on a wide range of benchtop and handheld drill equipment. A ball bearing design supports smooth, consistent tightening and grip under load. The steel chuck body is built for repeated use in production and maintenance environments. Machinists, tool-and-die technicians, and maintenance trades are the primary installers.

This chuck fits applications where a keyless design speeds up bit changes without sacrificing holding force. Typical install scenarios include benchtop drill presses, handheld power drills, and light-duty CNC or manual milling setups using a 1/2-20 threaded spindle. The 43 mm sleeve diameter keeps the chuck compact for work in tighter clearances. Its capacity range makes it suitable for both fine-detail drilling with small bits and standard through-hole work with 1/2 inch shanks. Production shops and MRO environments benefit from the tool-free bit changes that keyless operation provides.

Installation Notes

Installation is performed by a machinist or qualified shop technician. Power down and disconnect the drill or drill press from its power source before removing the existing chuck. Thread the chuck onto the 1/2-20 spindle by hand first, then secure per the tool manufacturer's guidance. Do not over-torque the spindle thread; follow the drill or press manufacturer's specifications for final seating.
