Value Collection 290-1179 Lathe Chuck Key 3-jaw Chuck

Product Description

The VALUE COLLECTION 290-1179 is a lathe chuck key designed for tightening and loosening 3-jaw lathe chucks in machining and metalworking environments. The key features a 3/4 inch square drive and a 5-1/2 inch body length, providing adequate leverage for chuck operations on compatible lathe sizes. This is a manually operated, non-self-ejecting key. Machinists and tool and die technicians working with bench lathes and floor-mounted lathes are the primary users. The compact body length suits both production and maintenance applications where a reliable, straightforward chuck key is needed without additional safety-ejection mechanisms.

This chuck key is suited for use with 3-jaw chucks with chuck diameter compatibility of 20 inches and 25 inches. It fits standard lathe setups found in machine shops, manufacturing facilities, and trade training environments. The 3/4 inch square drive engages the chuck key sockets on compatible chuck bodies. Because this key is not self-ejecting, operators must follow shop safety protocols to remove the key from the chuck before engaging the lathe spindle.

Installation Notes

Chuck key service is performed by qualified machinists following established shop safety procedures. Always confirm the lathe spindle is fully stopped and the machine is powered down before inserting or removing the chuck key. Never leave the chuck key inserted in the chuck when the lathe is unattended or prior to spindle engagement. Consult the lathe and chuck manufacturer documentation for proper tightening procedure and jaw seating guidance.
