It accepts drill bits and tooling from 1\/8 inch up to 5\/8 inch in diameter, covering a broad range of hole-making and boring applications. The chuck body is constructed from steel and runs on a ball bearing mechanism that supports smooth, repeatable tool changes without a key. With a sleeve diameter of approximately 2.05 inches (52 mm) and a closed length of approximately 4.13 inches (105 mm), it is sized for benchtop drill presses, light machine tools, and portable power equipment. Machinists, toolroom technicians, and maintenance trades install this chuck as a direct replacement or upgrade on compatible JT33 spindles.\u003c\/p\u003e\u003cp\u003eThis chuck suits residential shop equipment and light industrial machine tools where a JT33 tapered mount is standard. Typical installations include benchtop and floor-model drill presses, milling machine quill attachments, and similar rotating-spindle equipment. The keyless design allows rapid bit changes in production or service environments where downtime must be kept short. Its steel construction handles the repetitive clamping forces common in drilling steel, aluminum, wood, and plastics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKeyless sleeve design enables fast, tool-free bit changes\u003c\/li\u003e\n\u003cli\u003eCapacity range of 1\/8 inch to 5\/8 inch accommodates common drill bit sizes\u003c\/li\u003e\n\u003cli\u003eJT33 tapered mount interfaces directly with compatible spindles, no adapter required\u003c\/li\u003e\n\u003cli\u003eBall bearing construction supports smooth rotation and consistent clamping force\u003c\/li\u003e\n\u003cli\u003eSteel chuck body provides durability under repeated use\u003c\/li\u003e\n\u003cli\u003eSleeve diameter of approximately 2.05 inches (52 mm) fits standard chuck guard clearances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with machine tool spindles fitted with a JT33 Jacobs taper mount.

Power off and lock out the machine at the disconnect before removing or seating the chuck. Seat the JT33 taper by driving the chuck onto the spindle with a sharp mallet strike through a wood block to protect the sleeve — never strike the sleeve directly. Inspect the taper surfaces for burrs or contamination before assembly, as debris on the mating taper will cause runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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\u003eSleeve Diameter\u003c\/strong\u003e: approximately 2.05 inches (52 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: approximately 4.13 inches (105 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: approximately 3.74 inches (95 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.51 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: CKS1607020MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737118310706,"sku":"CKS1607020MSC","price":174.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3eecfa3d32ad792526459ecc07732a5.jpg?v=1788784516","url":"https:\/\/voomisupply.com\/products\/accupro-cks1607020msc-keyless-drill-chuck-jt33-5-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
