Built with a steel chuck body and ball bearing construction, it accepts round-shank tooling from 1\/8 inch up to 5\/8 inch. The 1\/2-20 threaded mount is a standard interface found on a wide range of benchtop and handheld drill platforms. With a sleeve diameter of 52 millimeters and a closed length of approximately 4.13 inches, this chuck is sized for general-purpose drilling work in fabrication, maintenance, and production environments. Installation and service are typically performed by machinists, tool-and-die technicians, and industrial maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThis chuck fits applications where quick bit changes and consistent grip across the full capacity range are priorities. The keyless design eliminates the need for a chuck key, making it practical for high-frequency tooling changes on drill presses, portable drills, and similar equipment. The ball bearing mechanism supports smooth operation and repeatable runout performance. It is suited for light to moderate-duty drilling in metal, wood, and plastic in both shop and field maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKeyless operation allows tool-free bit changes across the full capacity range\u003c\/li\u003e\n  \u003cli\u003eAccepts shank diameters from 1\/8 inch to 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003eBall bearing construction for smooth chuck operation and consistent grip\u003c\/li\u003e\n  \u003cli\u003eSteel chuck body for durability in production and maintenance use\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 threaded mount interfaces with standard drill spindles\u003c\/li\u003e\n  \u003cli\u003e52 millimeter sleeve diameter with a closed length of approximately 4.13 inches\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 portable drills equipped with a 1\/2-20 threaded spindle mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance mechanic. Disconnect and lock out all power to the drill before removing or installing a chuck. Inspect the spindle threads for damage or debris before threading on the new chuck, and confirm full thread engagement before operation. Do not use impact methods to seat the chuck that could damage spindle threads or bearing races.\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: 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: 52 millimeters (approximately 2.05 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 105 millimeters (approximately 4.13 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 95 millimeters (approximately 3.74 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.56 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CKS1610020MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753157263666,"sku":"CKS1610020MSC","price":173.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f742efcddcb3297c90a2674eaf2dca74.jpg?v=1788933344","url":"https:\/\/voomisupply.com\/products\/accupro-cks1610020msc-keyless-drill-chuck-1-8-to-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
