It accepts round-shank drill bits and tooling from 1\/32 inch to 1\/2 inch in diameter, secured through a JT33 Jacobs taper mount. The keyless sleeve design allows for hand-tightening and quick bit changes without a separate chuck key. Internal ball bearings support smooth, concentric rotation at spindle speeds up to 10,000 RPM. The chuck body is constructed from steel for durability under repeated use. It is installed by machinists and toolroom technicians on drill presses, lathes, and milling machines requiring a JT33 taper interface.\u003c\/p\u003e\u003cp\u003eThis chuck suits benchtop and floor-model drill presses used in production, maintenance, and toolroom environments. Its 1\/2 inch maximum capacity covers a wide range of standard twist drills, step drills, and similar tooling. The keyless design is well-suited to applications involving frequent bit changes. The JT33 taper mount is a common standard on light- to medium-duty drilling spindles, making this chuck a practical direct replacement in many shop setups. No specific OEM model compatibility is stated in available product data.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKeyless sleeve for tool-free bit changes without a chuck key\u003c\/li\u003e\n\u003cli\u003eJT33 Jacobs taper mount for direct spindle installation\u003c\/li\u003e\n\u003cli\u003eCapacity range from 1\/32 inch to 1\/2 inch (0.0313 to 0.5000 inches)\u003c\/li\u003e\n\u003cli\u003eBall bearing construction supports smooth rotation up to 10,000 RPM\u003c\/li\u003e\n\u003cli\u003eSteel chuck body for shop-floor durability\u003c\/li\u003e\n\u003cli\u003eClosed length of 4.055 inches and open length of 3.583 inches for compact spindle clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drill presses, lathes, and similar drilling equipment with a JT33 Jacobs taper spindle.

Power down and lock out the machine before mounting or removing the chuck. The JT33 taper is seated by pressing the chuck firmly onto the spindle; a chuck removal wedge or arbor press is typically used for disassembly. Inspect the spindle taper and chuck bore for debris or damage before seating to ensure concentric runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Capacity\u003c\/strong\u003e: 1\/32 inch (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum 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: JT33\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: PN01307000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730480890162,"sku":"PN01307000MSC","price":273.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b1182e87e062b4a7552cfcdbdf39d0a.jpg?v=1788718211","url":"https:\/\/voomisupply.com\/products\/accupro-pn01307000msc-keyless-drill-chuck-1-2-in-jt33","provider":"Voomi Supply","version":"1.0","type":"link"}
