Apex Tools Group Llc 30825 Chuck Key 3/8 1/2 Inch

Product Description

The APEX TOOLS GROUP LLC 30825 is a Jacobs-style chuck key designed to tighten and loosen keyed drill chucks in workshop and job-site settings. It fits both 3/8 inch and 1/2 inch chucks and features a 15/64 inch pilot shank that indexes into the chuck body for a secure, slip-free engagement. At 0.12 pounds, it is a lightweight single-piece tool suited for use by electricians, plumbers, HVAC techs, and general trades professionals who rely on keyed chuck drills during rough-in and installation work.

This chuck key is appropriate for use with standard keyed drill chucks commonly found on corded and benchtop drill presses as well as handheld drills used in residential and light commercial trade applications. It ships as a single unit and is intended as a direct replacement or spare for job boxes and tool kits where a lost or worn chuck key needs to be swapped out quickly without pulling the tool from service.

Installation Notes

Ensure the drill or drill press is powered off and unplugged before inserting the chuck key into the chuck body. Insert the pilot shank fully into the chuck port before applying torque to avoid damaging the chuck teeth. Chuck keys should never be left inserted in a chuck when the tool is not actively being adjusted. Licensed electricians and trade professionals should follow applicable OSHA hand-tool safety guidelines when servicing keyed chuck equipment.
