It features a CV40 taper shank for direct spindle mounting and accepts ER16 collets with a clamping range of 0.5 mm to 10 mm. The chuck is balanced to 20,000 RPM, making it suitable for high-speed cutting operations where runout control and vibration reduction are critical. A through-coolant design channels coolant directly to the cutting zone, extending tool life and improving chip evacuation. With a 4-inch projection and an overall length of 169.85 mm, this chuck positions tooling accurately within the work envelope. Machinists and toolroom technicians install this chuck as a standard toolholding solution on compatible machining centers.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is intended for use on CNC vertical and horizontal machining centers equipped with a CV40 spindle interface. The ER16 collet system accommodates a wide range of end mills, drills, and reamers within the 0.5 mm to 10 mm capacity range. The 4-inch projection suits applications where extended reach is needed to clear fixtures or deep-pocket workpiece geometries. Through-coolant capability makes it well suited for materials and operations that require directed coolant flow at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet system with 0.5 mm to 10 mm clamping capacity\u003c\/li\u003e\n  \u003cli\u003eCV40 taper shank for direct spindle mounting\u003c\/li\u003e\n  \u003cli\u003eBalanced to 20,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design for directed coolant delivery to the cutting zone\u003c\/li\u003e\n  \u003cli\u003e4-inch projection for extended reach within the work envelope\u003c\/li\u003e\n  \u003cli\u003eOverall length of 169.85 mm for consistent tool length management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CNC machining centers equipped with a CV40 taper spindle interface and ER16 collets within the 0.5 mm to 10 mm capacity range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal should be performed by a qualified machinist or toolroom technician with the spindle fully powered down and locked. Use a properly rated torque wrench and ER collet nut spanner to seat collets and tighten the retention nut to the machine tool builder's specified torque. Inspect the taper shank and spindle bore for contamination or wear before assembly, as debris on the taper interface directly affects runout. Verify through-coolant port alignment with the machine spindle coolant passage before initiating coolant flow.\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: CV40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 10.00 mm\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: 169.85 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 38.25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.06 inches x 4.33 inches x 4.33 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.69 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: 6693875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732482425138,"sku":"6693875","price":275.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90a17f55f8ff53bc8455328a0672c947.jpg?v=1788743444","url":"https:\/\/voomisupply.com\/products\/kennametal-6693875-er16-collet-chuck-cv40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
