It accepts round-shank tooling from 3\/64 inch (0.0591 inch decimal) up to 1\/2 inch (0.500 inch decimal), covering the most common drill bit sizes used in metalworking and fabrication shops. The chuck mounts via a JT33 Jacobs taper and uses a K2 key for tightening. The sleeve diameter measures 46 millimeters, and the chuck body is constructed from steel. A Positive Drive Slot is built in to help prevent bit slippage under load.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for professional trade and industrial applications where a reliable JT33-mount keyed chuck is needed on stationary or portable drilling equipment. It is appropriate for machinists, tool-and-die shops, HVAC fabricators, pipefitters, and maintenance technicians who run drill presses or similar spindle equipment. The keyed design provides greater clamping force compared to keyless chucks, making it a practical choice for larger-diameter or high-torque drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCapacity range of 3\/64 inch to 1\/2 inch accommodates a wide variety of standard drill bit shanks\u003c\/li\u003e\n\u003cli\u003eJT33 tapered mount for direct spindle installation without additional adapters on compatible machines\u003c\/li\u003e\n\u003cli\u003eKeyed chuck with K2 key delivers firm, consistent bit clamping under load\u003c\/li\u003e\n\u003cli\u003ePositive Drive Slot helps prevent bit rotation or slippage during drilling\u003c\/li\u003e\n\u003cli\u003ePlain bearing construction keeps the design simple and serviceable\u003c\/li\u003e\n\u003cli\u003eSteel chuck body for durability in production and maintenance environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on drill press spindles, lathes, and milling machine spindles with a JT33 Jacobs taper mount.

Power down and lock out the machine before seating or removing the chuck. The JT33 taper should be cleaned and free of burrs, oil, or debris before driving the chuck onto the spindle to ensure full seating. Use a draw bar or arbor press as appropriate for the machine type; do not strike the chuck directly with a hammer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Chuck Capacity\u003c\/strong\u003e: 3\/64 inch (0.0591 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Chuck Capacity\u003c\/strong\u003e: 1\/2 inch (0.500 inch)\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: Keyed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Number\u003c\/strong\u003e: K2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Plain\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: 46 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 86 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 71 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.92 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional Feature\u003c\/strong\u003e: Positive Drive Slot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: CY01307040MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741704454450,"sku":"CY01307040MSC","price":148.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab23bf16845f48d8a5a54ecb98c21d9e.jpg?v=1788833015","url":"https:\/\/voomisupply.com\/products\/accupro-cy01307040msc-keyed-drill-chuck-jt33-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
