It features a 5\/32 inch (0.1575 inch decimal) pilot diameter and is sized for use with 1\/4 inch capacity chucks. This type of key is a standard accessory in machine shops, fabrication environments, and general trade work wherever a keyed drill chuck requires frequent bit changes. It weighs 0.13 pounds and is sold individually. Machinists, tool-and-die workers, and general tradespeople keep these on hand as direct replacements or backups for lost or worn chuck keys.\u003c\/p\u003e\n\u003cp\u003eThis chuck key is intended for use with 1\/4 inch capacity keyed drill chucks that accept a CK3 key. Typical applications include benchtop drill presses, portable electric drills with keyed chucks, and light-duty machining setups. It suits both shop and field use where a compact, low-capacity chuck key is needed for routine bit changes or chuck maintenance. The key number CK3 and pilot diameter of 5\/32 inch are the primary fitment identifiers when cross-referencing compatible chucks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCK3 key number for straightforward cross-reference with compatible chuck models\u003c\/li\u003e\n  \u003cli\u003e5\/32 inch pilot diameter (0.1575 inch decimal) for precise engagement with the chuck pilot hole\u003c\/li\u003e\n  \u003cli\u003eSized for 1\/4 inch capacity keyed drill chucks\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.13 pounds — easy to store and handle on the bench or in the field\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit, suitable for individual replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4 inch capacity keyed drill chucks that require a CK3 key.

Insert the pilot pin of the chuck key fully into the chuck pilot hole before applying torque to avoid slippage or damage to the chuck teeth. Do not use a chuck key as a pry tool or apply force beyond normal hand tightening. Replace any chuck key that shows signs of wear, rounding, or cracking to maintain secure chuck engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Number\u003c\/strong\u003e: CK3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 5\/32 inches (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: 1\/4 inch capacity chuck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Number Compatibility\u003c\/strong\u003e: 6H\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: 685.62844178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735727276338,"sku":"685.62844178","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a45989b6661c29ade36c7b1d38cf8eb.jpg?v=1788773810","url":"https:\/\/voomisupply.com\/products\/accupro-685-62844178-drill-chuck-key-ck3-5-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
