It accepts ER16 collets with a clamping range of 0.51 mm to 10 mm (0.0200 to 0.3937 inches), making it suitable for a broad range of small-diameter cutting tools including end mills, drills, and reamers. The chuck features a 4-inch projection and an overall length of 8 inches. Through-spindle and DIN flange coolant delivery is supported, directing coolant directly to the cutting zone for improved chip evacuation and tool life. The unit is balanced to 12,000 RPM and actuated with a wrench via the included collet nut.\u003c\/p\u003e\u003cp\u003eThis collet chuck is suited for production machining environments where consistent tool holding and coolant-through capability are required. It fits CAT50 spindle tooling configurations common in heavy-duty vertical and horizontal machining centers used in metalworking, aerospace, and general manufacturing applications. The ER16 collet series is widely used for light to medium-duty milling and drilling operations requiring precise, repeatable tool runout. Installation and tool changes are performed by qualified machine operators or toolroom technicians using a standard ER collet wrench and torque procedure per the machine tool manufacturer guidelines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER16 collet system with clamping range of 0.51 mm to 10 mm\u003c\/li\u003e\n\u003cli\u003eCAT50 taper shank for direct spindle mounting on compatible machining centers\u003c\/li\u003e\n\u003cli\u003e4-inch projection and 8-inch overall length for reach into deep workpiece features\u003c\/li\u003e\n\u003cli\u003eThrough-spindle and DIN flange coolant delivery for active cutting zone cooling\u003c\/li\u003e\n\u003cli\u003eBalanced to 12,000 RPM for stable high-speed operation\u003c\/li\u003e\n\u003cli\u003eWrench-actuated collet nut with 27.99 mm (1.1020 inch) nut diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER16 collets in CAT50 taper spindle machining centers.

Power down and lock out the machining center spindle before mounting or removing the chuck. Use a calibrated ER collet wrench and follow the machine tool manufacturer torque specifications for the collet nut. Inspect the taper shank and spindle bore for contamination or damage before seating the tool holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: ER16\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: 0.51 mm (0.0200 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.1000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 27.99 mm (1.1020 inches)\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\u003eBalanced To RPM\u003c\/strong\u003e: 12,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.97 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2249707\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733537718578,"sku":"2249707","price":353.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad664f16738a59f4bc0bb43bc96d254a.jpg?v=1788756226","url":"https:\/\/voomisupply.com\/products\/kennametal-2249707-er16-collet-chuck-cat50-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
