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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 4-inch diameter lathe chucks\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch square drive size for positive engagement with chuck key sockets\u003c\/li\u003e\n  \u003cli\u003e3-1\/8-inch body length provides adequate leverage for standard chuck tightening\u003c\/li\u003e\n  \u003cli\u003eNon-self-ejecting design for straightforward manual operation\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.75 pounds for easy handling at the machine\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4-inch diameter lathe chucks that accept a 1\/4-inch square drive chuck key.
