Mounted on a CAT50 taper shank, this chuck accepts ER40 collets spanning a capacity range of 3.05 mm to 26 mm (0.12 inches to 1.0236 inches), accommodating a wide variety of cutting tool shanks. The 3-inch projection positions the collet nut away from the spindle face for clearance in deep-pocket and cavity work. Balanced to 12,000 RPM, it suits high-speed spindle applications where runout control and coolant delivery to the cutting edge are critical. Installation and adjustment are performed with a standard collet wrench acting on the actuator.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is used in production and job-shop environments on vertical and horizontal machining centers equipped with CAT50 spindles. Through-spindle and DIN flange coolant delivery routes coolant directly through the chuck and out at the cutting edge, reducing heat buildup and improving chip evacuation in ferrous and non-ferrous machining. The 7-inch overall length suits setups where extended reach is needed without sacrificing rigidity. Machinists and CNC setup technicians working in aerospace, die-mold, and general manufacturing will find this chuck appropriate for roughing and finishing operations where consistent clamping force across the full ER40 capacity range is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet system accepts tool shanks from 3.05 mm to 26 mm (0.12 to 1.0236 inches)\u003c\/li\u003e\n  \u003cli\u003eCAT50 taper shank for direct mounting to CAT50 spindle interfaces\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant compatible via through-spindle and DIN flange delivery\u003c\/li\u003e\n  \u003cli\u003eBalanced to 12,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003e3-inch projection provides clearance for deep-pocket and contoured workpiece geometry\u003c\/li\u003e\n  \u003cli\u003eWrench-actuated collet nut with 62.99 mm (2.48 inch) nose diameter for standard ER40 tooling accessories\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT50 spindle interfaces and the ER40 collet series.

Clean the CAT50 taper bore and chuck taper thoroughly before mounting to prevent seating errors that cause runout. Use a calibrated torque wrench and the appropriate ER40 collet nut spanner when tightening the collet nut to secure cutting tools. Verify runout at the tool tip with a dial indicator before returning the spindle to production use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 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: 3.05 mm (0.12 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 26 mm (1.0236 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2.48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 62.99 mm (2.48 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\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\u003eActuator Type\u003c\/strong\u003e: Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 12,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.2554 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112808\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2249716\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730966937906,"sku":"2249716","price":362.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75049f62b7989c8f57dce4f283154de4.jpg?v=1788725436","url":"https:\/\/voomisupply.com\/products\/kennametal-2249716-er40-collet-chuck-cat50-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
