Value Collection 290-1172 Lathe Chuck Key 5 Inch

Product Description

The VALUE COLLECTION 290-1172 is a lathe chuck key designed for use with lathe chucks that have a 5-inch chuck diameter. The key features a 2-3/8-inch body length and a 5/16-inch square drive size, making it compatible with standard T-handle and bar-style chuck key sockets of that drive dimension. This is a non-self-ejecting style key intended for manual tightening and loosening of lathe chuck jaws. Machinists and maintenance technicians use this type of accessory during workholding setup and changeover on metal lathes. The compact body length suits benchtop and floor-model lathes alike.

This chuck key is suited for use in machine shops, maintenance facilities, and vocational or production environments where manual lathe operation is standard. It is appropriate for residential workshops and light industrial settings where a 5-inch lathe chuck is in service. The 5/16-inch square drive engages the chuck's tightening socket directly, allowing secure jaw adjustment before cutting operations begin. No power tools are required for installation or use.

Designed as a replacement or spare chuck key for manual lathe chucks with a 5-inch chuck diameter and a 5/16-inch square drive socket.

Installation Notes

Always ensure the lathe is fully powered down and the spindle is at a complete stop before adjusting chuck jaws or handling the chuck key. Insert the square drive end fully into the chuck's tightening socket before applying torque to avoid slippage or socket damage. Remove the chuck key from the chuck immediately after tightening — never leave a chuck key inserted in a lathe chuck when the machine is unattended or about to be started. This tool requires no special installation and is ready for use as received.
