Apex Tools Group Llc 30250 Chuck Key 1/2 Inch

Product Description

The APEX TOOLS GROUP LLC 30250 is a Jacobs-style chuck key designed for use with 1/2 inch drill chucks. It features a 9/32 inch pilot shank that seats securely into the chuck's pilot hole, providing the leverage needed to tighten or loosen the chuck jaws firmly and precisely. This type of hand tool is a standard accessory on job sites and in shops wherever keyed drill chucks are in service. Electricians, plumbers, HVAC technicians, and general tradespeople keep chuck keys on hand to maintain control over bit seating and chuck wear. The part ships as a single unit and weighs 0.13 pounds.

This chuck key is suited for residential and commercial shop environments, maintenance shops, and trade service vehicles where 1/2 inch keyed drill chucks are commonly used. It is a direct-fit replacement when an original chuck key is lost or damaged, and it works in any setting where a Jacobs-pattern 1/2 inch chuck requires routine tightening or bit changes during drilling operations.

Installation Notes

Before changing bits or servicing the chuck, ensure the drill or drill press is powered off and unplugged or locked out per applicable safety procedures. Insert the pilot shank fully into the chuck pilot hole before applying torque to avoid slippage or damage to the chuck ring gear. Chuck keys should never be left inserted in a chuck when powering up a tool.
