It accepts round-shank drill bits and tooling from 1\/32 inch up to 1\/2 inch (0.0313 to 0.5000 inches). The chuck uses an internal ball bearing design that supports smooth rotation and consistent grip under load, with a maximum rated spindle speed of 10,000 RPM. The body and jaws are constructed from steel for durability in production and maintenance drilling applications. Machinists, toolroom technicians, and maintenance mechanics install this type of chuck on drill presses, milling machine spindles, and similar equipment requiring a JT6 interface.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for both light-duty and moderate-production drilling tasks where a keyless design speeds up bit changes without sacrificing clamping force. The keyless collar tightens and releases by hand, which is practical in high-cycle environments where operators swap tooling frequently. With a closed length of 4.055 inches and a sleeve diameter of 1.929 inches, it fits standard JT6 spindle configurations found on benchtop and floor-standing drill presses used in machine shops, fabrication facilities, and industrial maintenance settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKeyless design allows hand-tightening and fast bit changes without a chuck key\u003c\/li\u003e\n\u003cli\u003eAccepts tooling from 1\/32 inch to 1\/2 inch capacity\u003c\/li\u003e\n\u003cli\u003eJT6 tapered mount fits standard JT6 drill press and machine spindles\u003c\/li\u003e\n\u003cli\u003eBall bearing construction supports smooth operation up to 10,000 RPM\u003c\/li\u003e\n\u003cli\u003eAll-steel chuck body for durability in shop and production environments\u003c\/li\u003e\n\u003cli\u003eClosed length of 4.055 inches and sleeve diameter of 1.929 inches for compact fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with drill presses, milling machines, and similar equipment equipped with a JT6 tapered spindle mount.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or qualified maintenance technician. Power down and lock out the machine before mounting or removing the chuck from the spindle. The chuck seats onto the JT6 taper by firm hand-press or a light mallet tap against a wooden block — never strike the chuck body directly with a metal hammer. Verify that the taper and bore are clean and free of burrs before seating to ensure full contact and safe operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Chuck Capacity\u003c\/strong\u003e: 1\/32 inch (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Chuck Capacity\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Size\u003c\/strong\u003e: JT6\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\u003eClosed Length\u003c\/strong\u003e: 4.055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 3.583 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSleeve Diameter\u003c\/strong\u003e: 1.929 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 10,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.2 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: PN01308000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747653878066,"sku":"PN01308000MSC","price":273.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bdfad8292c506075f05ec216d98a25a.jpg?v=1788884099","url":"https:\/\/voomisupply.com\/products\/accupro-pn01308000msc-keyless-drill-chuck-jt6-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
