It accepts bit shanks from 1\/16 inch up to 1\/2 inch, making it suitable for a wide range of twist drills, step bits, and rotary accessories. The chuck uses a ball-bearing design for smooth, consistent tightening without a key. The 42 mm sleeve diameter and 1\/2-20 threaded mount are standard dimensions compatible with common benchtop and handheld drill platforms. An M6 screw is included for secure installation. This chuck is typically installed by machinists, maintenance technicians, and tool-repair professionals.\u003c\/p\u003e\n\u003cp\u003eThis keyless drill chuck fits applications where fast bit changes and reliable clamping force are priorities. The 1\/2-20 threaded mount is a common standard found on many benchtop drill presses and corded handheld drills used in light industrial and trade settings. The ball-bearing mechanism supports repeated use under moderate-duty drilling conditions. The steel construction provides durability for shop environments. Closed length is approximately 2.95 inches and open length is approximately 2.56 inches, making it a compact choice for space-limited setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKeyless design allows rapid bit changes without a separate chuck key\u003c\/li\u003e\n  \u003cli\u003eBall-bearing construction supports smooth tightening and consistent clamping\u003c\/li\u003e\n  \u003cli\u003e1\/16 to 1\/2 inch capacity covers a broad range of drill bit shank sizes\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 threaded mount is a widely used standard for drill compatibility\u003c\/li\u003e\n  \u003cli\u003e42 mm sleeve diameter for positive grip during tightening\u003c\/li\u003e\n  \u003cli\u003eIncludes M6 screw for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade chuck for drill presses and handheld drills with a 1\/2-20 threaded spindle mount accepting up to 1\/2 inch shank capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians. Power down and disconnect or de-energize the drill before removing or installing the chuck. The included M6 screw typically threads into the spindle bore to secure the chuck against reverse rotation — confirm correct screw direction before tightening. Use appropriate spindle wrenches to remove the existing chuck and seat the replacement squarely on the threaded spindle before final torquing.\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\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Chuck Capacity\u003c\/strong\u003e: 1\/2 inch (0.500 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: 1\/2-20\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: 42 mm (approximately 1.65 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\u003eIncludes\u003c\/strong\u003e: M6 Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 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: CPX1310030MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736320966962,"sku":"CPX1310030MSC","price":83.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c90a7723c291cd08ab798a6a655ab40.jpg?v=1788777202","url":"https:\/\/voomisupply.com\/products\/accupro-cpx1310030msc-keyless-drill-chuck-1-2-20-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
