It accepts ER16 collets with a clamping range of 0.51 mm to 10 mm (0.020 to 0.394 inches), making it suitable for a wide range of small-diameter tooling. The chuck features a 5-inch projection and through-coolant capability, delivering coolant directly to the cutting zone for improved tool life and chip evacuation. Weighing 2.85 pounds, this chuck is actuated by wrench and is balanced to 12,000 RPM for stable, vibration-free operation at typical production speeds.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is intended for use in machining centers equipped with CAT40 spindle interfaces. It suits residential toolroom and commercial production environments where precise, repeatable small-diameter tool holding is required. The through-spindle and DIN flange coolant delivery system supports high-speed drilling, reaming, and end milling operations. Tooling setups requiring a 5-inch gage-line projection benefit from this chuck where reach into deep fixtures or tall workpieces is necessary. Installation and setup are performed by machinists and CNC setup technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet system accepts tooling from 0.51 mm to 10 mm clamping capacity\u003c\/li\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting in CAT40-spindle machining centers\u003c\/li\u003e\n  \u003cli\u003e5-inch projection (127 mm) provides extended reach for deep-fixture applications\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design with through-spindle and DIN flange coolant delivery\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 1.102-inch (27.99 mm) collet nut diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER16 series collets in CAT40-spindle CNC machining centers equipped with through-spindle or DIN flange coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machining center spindle before inserting or removing the chuck. Use the appropriate ER16 collet wrench and spanner to torque the collet nut — do not use impact tools on the collet nut. Verify coolant port alignment with the spindle interface before running coolant-through operations.\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: 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: CAT40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.51 mm (0.020 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 10 mm (0.394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 5 inches (127 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 1.102 inches (27.99 mm)\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: 2.85 pounds\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: 1901046\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732723007794,"sku":"1901046","price":291.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9d0d90114d9d422a28b70cbc07b8755.jpg?v=1788746043","url":"https:\/\/voomisupply.com\/products\/kennametal-1901046-er16-collet-chuck-cat40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
