It accepts drill bit shanks from 1\/32 inch up to 1\/2 inch (0.0313 to 0.5000 inches) and mounts via an integral 3MT (Morse Taper No. 3) shank. The keyless design allows tool changes without a chuck key, speeding up bit swaps during production or setup. Built from steel with ball bearing construction, this chuck delivers a TIR (Total Indicator Runout) of 0.0016 inches, supporting precise hole location and clean entry. Rated to 10,000 RPM, it suits both low-speed drilling and higher-speed light-duty work.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for drill presses, milling machines, and similar machine tool spindles that accept a No. 3 Morse Taper. It is a standard fit for shop environments where fast, repeatable tool changes are needed without sacrificing concentricity. The 1.89-inch sleeve diameter and compact taper shank profile keep it compatible with a wide range of production and job-shop machines. Machinists, toolroom technicians, and CNC setup personnel are the primary installers of this component.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKeyless chuck design for fast, tool-free bit changes\u003c\/li\u003e\n\u003cli\u003eCapacity range: 1\/32 inch to 1\/2 inch (0.0313 to 0.5000 inches)\u003c\/li\u003e\n\u003cli\u003eIntegral 3MT taper shank mount for direct spindle installation\u003c\/li\u003e\n\u003cli\u003eBall bearing construction supports smooth, consistent clamping force\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0016 inches for accurate hole placement\u003c\/li\u003e\n\u003cli\u003eMaximum rated speed of 10,000 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-mount replacement chuck for machine tool spindles with a No. 3 Morse Taper (3MT) socket.

Power down and lock out the machine spindle completely before installing or removing the chuck. Seat the taper shank firmly by hand and then with a mallet strike if required by the machine manufacturer — never force the shank into a dirty or damaged taper socket. Inspect the spindle bore and chuck taper for nicks, burrs, or contamination before assembly to maintain TIR performance.\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: Integral Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Size\u003c\/strong\u003e: 3MT (Morse Taper No. 3)\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: 1.89 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 3.622 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 3.150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0016 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 10,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.9 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: SPS1303000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750194807090,"sku":"SPS1303000MSC","price":374.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f18871656fbfb83aa7e1f6eddde3295d.jpg?v=1788914232","url":"https:\/\/voomisupply.com\/products\/accupro-sps1303000msc-keyless-drill-chuck-1-2-inch-3mt","provider":"Voomi Supply","version":"1.0","type":"link"}
