It accepts round-shank drill bits and tooling from 13\/64 inch (0.1969 inches) up to 3\/4 inch (0.7500 inches) in diameter. The chuck body is constructed of steel and uses a plain bearing design for consistent grip and repeatable tool seating. The sleeve diameter measures 65 mm, and the chuck uses a K4 key for tightening and releasing tooling. Machinists, tool-and-die technicians, and maintenance mechanics working with drill presses, mills, or lathes configured for threaded-spindle chucks will find this a direct-fit replacement or upgrade option.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for bench-top and floor-standing drill presses, as well as milling machines and other machine tool spindles threaded to the 5\/8-16 standard. Its capacity range covers the majority of common fractional and metric drill bit shanks used in general metalworking, woodworking, and maintenance applications. The keyed design provides higher clamping force retention compared to keyless alternatives, making it appropriate for higher-torque drilling operations in production or shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCapacity range from 13\/64 inch to 3\/4 inch accommodates a wide variety of drill bit shank sizes\u003c\/li\u003e\n\u003cli\u003eThreaded mount with 5\/8-16 thread for direct spindle installation without an adapter arbor\u003c\/li\u003e\n\u003cli\u003eSteel chuck body for durability in production and maintenance shop conditions\u003c\/li\u003e\n\u003cli\u003eK4 keyed design delivers positive clamping force suitable for heavier drilling operations\u003c\/li\u003e\n\u003cli\u003e65 mm sleeve diameter provides a solid grip surface for key engagement\u003c\/li\u003e\n\u003cli\u003ePlain bearing construction for straightforward, low-maintenance operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a threaded-mount replacement or upgrade chuck for drill press and machine tool spindles with a 5\/8-16 threaded spindle nose.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician. Power down and lock out the machine at the main disconnect before removing the existing chuck or mounting this unit. Thread the chuck onto the spindle nose by hand first to confirm thread engagement, then tighten securely according to the machine manufacturer's spindle torque guidance. Verify runout with a dial indicator after installation before returning the machine to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Chuck Capacity\u003c\/strong\u003e: 13\/64 inch (0.1969 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Chuck Capacity\u003c\/strong\u003e: 3\/4 inch (0.7500 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\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: K4\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: 65 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 110 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 85 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.74 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: CY01911000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743152210226,"sku":"CY01911000MSC","price":260.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5b149b79ca91ba23371347514fdd978.jpg?v=1788843298","url":"https:\/\/voomisupply.com\/products\/accupro-cy01911000msc-keyed-drill-chuck-3-4-in-threaded","provider":"Voomi Supply","version":"1.0","type":"link"}
