It accepts bit shanks from 1\/16 inch up to 1\/2 inch, covering the full range of common twist drills, step bits, and accessories. The 1\/2-20 threaded mount is the standard spindle thread found on a wide range of benchtop and handheld drill equipment. A ball bearing design supports smooth, consistent tightening and grip under load. The steel chuck body is built for repeated use in production and maintenance environments. Machinists, tool-and-die technicians, and maintenance trades are the primary installers.\u003c\/p\u003e\u003cp\u003eThis chuck fits applications where a keyless design speeds up bit changes without sacrificing holding force. Typical install scenarios include benchtop drill presses, handheld power drills, and light-duty CNC or manual milling setups using a 1\/2-20 threaded spindle. The 43 mm sleeve diameter keeps the chuck compact for work in tighter clearances. Its capacity range makes it suitable for both fine-detail drilling with small bits and standard through-hole work with 1\/2 inch shanks. Production shops and MRO environments benefit from the tool-free bit changes that keyless operation provides.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKeyless design allows fast, tool-free bit changes by hand\u003c\/li\u003e\n\u003cli\u003eAccepts bit shanks from 1\/16 inch to 1\/2 inch (0.0625 to 0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e1\/2-20 threaded mount fits standard drill and drill press spindles\u003c\/li\u003e\n\u003cli\u003eBall bearing construction supports smooth chuck operation and consistent clamping\u003c\/li\u003e\n\u003cli\u003eSteel chuck body for durability in production and shop environments\u003c\/li\u003e\n\u003cli\u003e43 mm sleeve diameter in a compact closed length of approximately 2.95 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or upgrade for drills and drill presses with a 1\/2-20 threaded spindle mount.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or qualified shop technician. Power down and disconnect the drill or drill press from its power source before removing the existing chuck. Thread the chuck onto the 1\/2-20 spindle by hand first, then secure per the tool manufacturer's guidance. Do not over-torque the spindle thread; follow the drill or press manufacturer's specifications for final seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Chuck Capacity\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Chuck Capacity\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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: 1\/2-20 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Type\u003c\/strong\u003e: Keyless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball\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: 43 mm (approximately 1.69 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 75 mm (approximately 2.95 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 65 mm (approximately 2.56 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.57 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CPL1310000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729409114418,"sku":"CPL1310000MSC","price":70.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cb291e0f8fb8a4f19088148e75907a4.jpg?v=1788704284","url":"https:\/\/voomisupply.com\/products\/accupro-cpl1310000msc-drill-chuck-keyless-1-2-20","provider":"Voomi Supply","version":"1.0","type":"link"}
