Apex Tools Group Llc 30249 Chuck Key 1/4 and 3/8 Inch

Product Description

The APEX TOOLS GROUP LLC 30249 is a Jacobs-style chuck key designed to tighten and release 1/4 inch and 3/8 inch drill chucks. The 1/4 inch pilot shank seats securely into the chuck housing to prevent slippage during operation. This type of chuck key is a standard hand tool used by electricians, HVAC technicians, plumbers, and general trade professionals who work with corded or benchtop drills. It ships as a single unit and is a direct, low-profile replacement when an original key is lost or damaged on a jobsite.

This chuck key fits 1/4 inch and 3/8 inch keyed drill chucks of the Jacobs style, which are common on corded drills, drill presses, and benchtop equipment found in residential and light commercial trade work. It is a single-piece tool requiring no assembly. Trade professionals keep a spare on hand to avoid downtime when the original key is misplaced during a service call.
