It features a 5\/16 inch pilot diameter (0.3150 inches decimal) that seats securely into the chuck body to provide the leverage needed to tighten or loosen drill bits and other rotary tooling. This key is a standard hand tool used in machine shops, fabrication facilities, and maintenance environments wherever a keyed drill chuck is in service. Machinists, maintenance technicians, and tool crib staff are the primary users. It is a direct-use accessory requiring no power connection or modification.\u003c\/p\u003e\n\u003cp\u003eThis chuck key is suited for benchtop drill presses, floor-standing drill presses, and other equipment fitted with a keyed 1\/2 inch drill chuck.

Ensure the drill press or machine is powered off and unplugged before changing bits or operating the chuck key. Store the key away from the chuck when the machine is in use — never leave a chuck key inserted in a rotating or powered spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Number\u003c\/strong\u003e: CK5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 5\/16 inches (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: 1\/2 inch capacity chuck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 685.62844238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730837733682,"sku":"685.62844238","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca1e52b876fd9e07ac8093521f49fe32.jpg?v=1788723658","url":"https:\/\/voomisupply.com\/products\/accupro-685-62844238-drill-chuck-key-ck5-5-16-in-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
