It accepts drill bits and round-shank tooling from 1\/8 inch to 5\/8 inch capacity, with a ball bearing design that supports smooth, consistent jaw actuation without a key. The integral taper shank mounts directly into a 4MT spindle bore, eliminating the need for an adapter. Rated to 6000 RPM, this chuck is built for production-level drilling operations where speed and repeatability matter. The steel construction and 0.0016 inch TIR specification make it a solid choice for general-purpose and precision drilling work.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for vertical machining centers, drill presses, radial arm drills, and lathes configured with a 4MT spindle. Typical applications include production drilling in metal fabrication, machine shops, and tool rooms where a keyless design improves cycle time between tool changes. The 5\/8 inch maximum capacity covers the majority of common twist drill and reamer shank sizes used in those environments. Machinists and machine tool operators are the primary installers and users of this chuck.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKeyless design allows fast tool changes without a chuck key\u003c\/li\u003e\n\u003cli\u003eBall bearing mechanism supports smooth jaw operation and consistent grip\u003c\/li\u003e\n\u003cli\u003e4MT integral taper shank mounts directly to compatible spindle bores\u003c\/li\u003e\n\u003cli\u003e6000 RPM maximum speed rating suitable for production drilling\u003c\/li\u003e\n\u003cli\u003e0.0016 inch TIR for repeatable tool concentricity\u003c\/li\u003e\n\u003cli\u003eSteel chuck body for durability in industrial environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with drilling machines, lathes, and machining centers equipped with a 4MT (Morse Taper 4) spindle bore.

Power down and lock out the machine before mounting or removing the chuck from the spindle. Ensure the 4MT taper and spindle bore are clean and free of burrs or debris before seating the shank. Use a proper drift and mallet for removal to avoid damaging the taper surfaces.\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 (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Chuck Capacity\u003c\/strong\u003e: 5\/8 inch (0.6250 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: 4MT (Morse Taper 4)\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\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSleeve Diameter\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 3.780 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 3.346 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: 6000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.36 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: SPS1604000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754490233138,"sku":"SPS1604000MSC","price":434.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da679e13f60194a110a233a44bd195df.jpg?v=1788945940","url":"https:\/\/voomisupply.com\/products\/accupro-sps1604000msc-keyless-drill-chuck-4mt-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
