With a body length of 6-3\/8 inches and an actual key square size of 11\/16 inches, this tool delivers the leverage and fit needed for reliable chuck engagement. It is compatible with 20-inch and 25-inch chuck diameters, making it a practical fit for mid- to large-size lathe setups. Machinists, tool-and-die workers, and maintenance technicians working with manual lathes will find this key a straightforward, functional addition to the shop floor.\u003c\/p\u003e\n\u003cp\u003eThis chuck key is suited for use with manual lathe chucks in manufacturing, metalworking, and machine maintenance environments. It fits chucks with 20-inch and 25-inch diameter ratings, which are common in industrial and production-grade turning equipment. The 11\/16-inch square drive mates directly with the chuck's key socket to provide positive engagement during jaw adjustment. It is not a self-ejecting design, so standard manual operation applies. Typical users include machinists and shop technicians performing chuck changeovers or jaw adjustments on lathes in production or job-shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-3\/8 inch body length provides adequate leverage for mid- to large-size chuck operation\u003c\/li\u003e\n  \u003cli\u003e11\/16 inch square key size for positive socket engagement\u003c\/li\u003e\n  \u003cli\u003eCompatible with 20-inch and 25-inch chuck diameters\u003c\/li\u003e\n  \u003cli\u003eNon-self-ejecting design for standard manual use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.75 pounds for easy single-hand handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with manual lathe chucks rated at 20-inch and 25-inch chuck diameters requiring an 11\/16-inch square key drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways disengage the lathe from power and bring the spindle to a complete stop before using the chuck key. Insert the square drive fully into the chuck socket before applying torque to avoid socket wear or slippage. Remove the chuck key from the socket immediately after completing the adjustment — never leave a chuck key inserted in a stationary or running lathe. Follow applicable shop safety protocols and machine guarding requirements during chuck service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 6-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Square Size\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Diameter Compatibility\u003c\/strong\u003e: 20 inches, 25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelf-Ejecting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112120\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 290-1178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700054458674,"sku":"290-1178","price":81.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/202b306f61640fffa2cb11c71fc364ec.jpg?v=1788385453","url":"https:\/\/voomisupply.com\/products\/value-collection-290-1178-lathe-chuck-key-20-25-in","provider":"Voomi Supply","version":"1.0","type":"link"}
