Apex Tools Group Llc 30827 Chuck Key 1/4 3/8 Inch

Product Description

The APEX TOOLS GROUP LLC 30827 is a Jacobs-style chuck key designed to tighten and release drill chuck jaws on portable and benchtop drilling equipment. It fits 1/4 inch and 3/8 inch chuck sizes and uses a 13/64 inch pilot shank to seat securely in the chuck's pilot hole before turning. At 0.07 pounds, this is a compact, single-piece hand tool. Electricians, HVAC technicians, plumbers, and general trades workers use chuck keys daily when swapping drill bits on keyed chucks. It is sold as a single unit and is a direct replacement when the original key is lost or damaged.

This chuck key is suited for use with keyed drill chucks found on corded electric drills, drill presses, and similar rotating tools common in residential and light commercial trade work. The dual-size compatibility — 1/4 inch and 3/8 inch — makes it useful across a range of smaller chuck sizes without requiring multiple keys on the job. It is particularly practical for technicians who carry a basic tool kit and need a reliable spare.

Installation Notes

Always ensure the drill or drill press is powered off and unplugged before inserting or removing the chuck key. Insert the pilot shank fully into the chuck's pilot hole before applying rotational force to avoid damaging the chuck teeth. Do not use power tools or impact drivers to drive a chuck key. This tool is intended for manual hand operation only.
