Value Collection ST12LARGE 4-way Drill Chuck Key

Product Description

The VALUE COLLECTION ST12LARGE is a four-way drill chuck key designed to service heavy-duty drill chucks ranging from 3/8 to 3/4 inches in size. A single tool handles four key numbers — K2, K3, K32, and K4 — eliminating the need to carry or source multiple individual keys. Weighing 0.5 pounds, it is built for repeated shop and field use by machinists, tool and die technicians, and maintenance professionals who work across multiple chuck sizes. Its multi-key design reduces downtime when switching between drill press setups or portable drilling equipment.

This chuck key is suited for industrial and commercial machine shop environments as well as maintenance facilities where multiple drill press or chuck configurations are in service. It is compatible with heavy-duty drill chucks from 3/8 to 3/4 inches. The four-way format makes it particularly practical in production settings where technicians move between different machines or chuck brands requiring different key sizes without stopping to locate a dedicated key for each unit.

Installation Notes

Chuck key service should be performed by a qualified machinist or maintenance technician. Always power down and de-energize the drill press or drilling equipment before inserting or removing the chuck key. Never leave a chuck key seated in the chuck when the machine is unattended or about to be powered on. Follow the equipment manufacturer guidelines for chuck tightening procedures.
