Value Collection 290-1177 Lathe Chuck Key 16 Inch

Product Description

The VALUE COLLECTION 290-1177 is a lathe chuck key designed to tighten and release lathe chucks with a 16-inch chuck diameter compatibility. The key features a 4-3/4-inch body length and a 5/8-inch square drive size, making it a practical hand tool for machinists and toolroom technicians working with large-capacity lathes. This is a non-self-ejecting style key, meaning the operator removes it manually after use. It is a single-piece, solid tool intended for direct engagement with the chuck body during workholding setup and changeover operations.

This chuck key is suited for use in machine shops, toolrooms, and manufacturing environments where large-bore lathes are in service. It is compatible with lathe chucks that accept a 5/8-inch square key drive and measure 16 inches in diameter. Typical applications include jaw adjustment on 3-jaw and 4-jaw chucks used in heavy turning operations. It is handled by machinists, tool and die technicians, and maintenance personnel responsible for lathe setup and operation.

Installation Notes
