Accupro CY00417000MSC Drill Chuck Threaded 5/16-24 Keyed

Product Description

The ACCUPRO CY00417000MSC is a keyed drill chuck designed for threaded-mount drilling applications. It accepts bit shanks from 1/64 inch (0.0118 inch) up to 5/32 inch (0.1563 inch), making it suited for small-diameter drilling work where precision and secure bit retention matter. The chuck uses a 5/16-24 threaded mount and features a 22 mm sleeve diameter. Construction is steel with a plain bearing design. Licensed tradespeople and machinists working with bench drills, drill presses, and compatible rotary tools will find this chuck a reliable replacement or upgrade for light-duty precision drilling setups.

This chuck is appropriate for light industrial, maintenance, and trade shop environments where small-diameter bits are routinely used. It fits threaded spindles with a 5/16-24 thread and is commonly installed on drill presses, hand drills, and rotary tools requiring a keyed chuck interface. The KO key type means a chuck key is required to tighten and release bits, providing positive grip during operation. It is a single-piece replacement unit packaged individually.

Installation Notes

Installation should be performed by a qualified machinist or trades professional familiar with rotary tool spindle work. Power down and disconnect the drill or drill press from its power source completely before removing or installing a chuck. Ensure the spindle threads are clean and undamaged before threading on the new chuck. Follow the tool manufacturer's guidelines for securing the chuck to the spindle to prevent loosening during operation.
