It accepts drill bit shanks from 1\/8 inch to 5\/8 inch (0.125 to 0.625 inches) and mounts via a 5\/8-16 threaded arbor interface. The chuck body is steel construction with a plain bearing, a sleeve diameter of 2.29 inches, and uses a K3 key for tightening. Closed length is 3.81 inches and open length is 2.84 inches. This chuck suits drill presses, lathes, and similar machine tool setups where precise, tool-free chuck changes are not required and positive key-tightened grip is preferred.\u003c\/p\u003e\n\u003cp\u003eThe JCM6232 is used in stationary machine tool applications including drill presses and milling machine setups that use a 5\/8-16 threaded spindle nose. It is appropriate for production shops, maintenance environments, and trade professionals who need a reliable keyed chuck for drilling steel, wood, plastics, or similar materials. The keyed design provides higher grip force than keyless alternatives, making it well suited for larger diameter bits and tougher materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCapacity range from 1\/8 inch to 5\/8 inch accommodates a wide variety of drill bit shank sizes\u003c\/li\u003e\n  \u003cli\u003e5\/8-16 threaded mount for direct spindle installation on compatible drill presses and lathes\u003c\/li\u003e\n  \u003cli\u003eK3 keyed tightening delivers positive grip force, reducing bit slippage under load\u003c\/li\u003e\n  \u003cli\u003eSteel chuck body for durability in repeated industrial and shop use\u003c\/li\u003e\n  \u003cli\u003e2.29-inch sleeve diameter with plain bearing construction\u003c\/li\u003e\n  \u003cli\u003eCompact closed length of 3.81 inches limits spindle-to-workpiece clearance loss\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or upgrade keyed drill chuck for drill presses, lathes, and machine tools equipped with a 5\/8-16 threaded spindle nose and requiring a chuck with 1\/8 to 5\/8 inch capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical trades professional with the machine fully powered down and locked out per OSHA lockout\/tagout procedures. Thread the chuck onto the 5\/8-16 spindle nose by hand until fully seated, then verify that the chuck runs true before applying load. Use the K3 chuck key to tighten the jaws onto tooling before each use and confirm the key is removed before starting the machine. Inspect jaw and sleeve condition periodically for wear that could affect concentricity or grip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Chuck Capacity\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Chuck Capacity\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Size\u003c\/strong\u003e: 5\/8-16 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Type\u003c\/strong\u003e: Keyed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Number\u003c\/strong\u003e: K3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSleeve Diameter\u003c\/strong\u003e: 2.29 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 3.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 2.84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\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: JACOBS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JCM6232\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JACOBS CHUCK","offers":[{"title":"Default Title","offer_id":67906671378738,"sku":"JCM6232","price":347.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa9c38bf2231ca75e9c562ff59914f03.jpg?v=1791170329","url":"https:\/\/voomisupply.com\/products\/jacobs-jcm6232-drill-chuck-1-8-to-5-8-in-threaded-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
