It accepts TG and PG100 series collets with a clamping range of 0.046 to 1 inch, making it versatile across a wide range of tool shank diameters. The chuck mounts via a CAT50 dual contact taper shank, providing both face and taper contact for improved rigidity and repeatability at the spindle. With a TIR of 0.0006 inches and balance rating of 15,000 RPM, this chuck is suited for high-speed finish milling, drilling, and reaming where runout control is critical. Through-spindle and DIN flange coolant delivery is supported.\u003c\/p\u003e\u003cp\u003eThis collet chuck is used in vertical and horizontal CNC machining centers equipped with CAT50 spindles. It is a standard tool for production shops and job shops running medium to large machining centers where CAT50 tooling is the platform. The 3.5-inch projection and 7.5-inch overall length make it appropriate for applications requiring reach beyond the spindle face while maintaining rigidity. Installation and tool changes are handled by CNC machinists and tool crib technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT50 dual contact taper shank for face and taper engagement, improving rigidity over standard V-flange contact alone\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0006 inches for tight runout control in precision machining operations\u003c\/li\u003e\n\u003cli\u003eBalanced to 15,000 RPM for compatibility with high-speed spindle applications\u003c\/li\u003e\n\u003cli\u003eThrough-spindle and DIN flange coolant delivery supported for chip evacuation and tool life\u003c\/li\u003e\n\u003cli\u003eAccepts TG and PG100 series single angle collets with capacity from 0.046 to 1 inch\u003c\/li\u003e\n\u003cli\u003e3.5-inch projection and 2.5-inch nose diameter provide reach and clearance in a variety of fixturing setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT50 dual contact taper spindles and compatible with TG series and PG100 series single angle collets with tool shank diameters from 0.046 to 1 inch.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed by a qualified CNC machinist following the machine tool manufacturer's tool change procedures. Power down and lock out the spindle before mounting or removing the chuck. The collet nut tightening torque is specified in the supplier data at 60 foot-pounds — use a calibrated spanner wrench designed for TG-style collet nuts and do not exceed the specified torque. Inspect the taper bore and spindle taper for chips or damage before seating the chuck to ensure full dual contact engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: Single Angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: TG and PG100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Dual Contact Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.046 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0006 inches (0.015 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 15,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle and DIN Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Tightening Torque\u003c\/strong\u003e: 60 ft\/lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.75 x 4.5 x 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 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: 771960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731309035826,"sku":"771960","price":236.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d118c3993e1bf9e03d586ce1b5d71bd7.jpg?v=1788729586","url":"https:\/\/voomisupply.com\/products\/accupro-771960-collet-chuck-cat50-dual-contact-tg-pg100","provider":"Voomi Supply","version":"1.0","type":"link"}
