Value Collection 290-1171 Lathe Chuck Key 4 Inch

Product Description

The VALUE COLLECTION 290-1171 is a lathe chuck key designed for use with 4-inch diameter lathe chucks. The key features a 3-1/8-inch body length and a 1/4-inch square drive size, making it a straightforward, purpose-built tool for tightening and loosening chuck jaws on manual lathes. This is a non-self-ejecting style key, meaning the operator removes it manually after use. Machinists and toolroom technicians keep this type of key at the lathe for routine workholding tasks. At 0.75 pounds, it is a lightweight, single-piece hand tool with no power source or installation required.

This chuck key is suited for manual lathe operations in machine shops, vocational training environments, and maintenance facilities. It is intended for use with 4-inch lathe chucks that accept a 1/4-inch square key drive. Typical applications include securing three-jaw and four-jaw chucks during workpiece setup and changeover. It is a general-purpose item appropriate for both production and toolroom use wherever a 4-inch chuck is in service.
