Value Collection 290-1176 Lathe Chuck Key 10 12 Inch Chuck

Product Description

The VALUE COLLECTION 290-1176 is a lathe chuck key designed for use with 10-inch and 12-inch diameter lathe chucks. The key features a 4-inch body length and a 9/16-inch square drive size, providing a secure fit and reliable torque transfer when tightening or loosening chuck jaws. Weighing 0.75 pounds, this is a manual, non-self-ejecting key suited for use in machine shops and metalworking environments. Machinists and tool and die workers rely on this type of chuck key for routine chuck operations on manual lathes.

This chuck key is appropriate for use on manual engine lathes and similar turning equipment equipped with 10-inch or 12-inch three-jaw or four-jaw chucks. It is well suited for production machine shops, maintenance departments, and vocational training environments where standard manual chuck operation is required. The non-self-ejecting design means the operator manually removes the key after use, making proper key discipline and safe handling practices essential during operation.

Installation Notes

Chuck key use and replacement is performed by machinists and machine tool operators. Before changing or seating a chuck key, ensure the lathe is powered off and the spindle is fully stopped. Always remove the chuck key from the chuck immediately after tightening or loosening jaw movement — never leave a key seated in a rotating or about-to-rotate chuck. Verify the square drive size matches the chuck socket before applying torque to avoid rounding the drive socket.
