It accepts ER11 series collets and features a 2.7559-inch projection with an overall length of 5.4488 inches. The chuck is balanced to 18,000 RPM, making it suitable for high-speed spindle applications where runout and vibration control are critical. Through-coolant capability, including through-spindle and DIN flange coolant delivery, allows directed coolant flow directly to the cutting zone. Machinists and CNC setup technicians are the primary installers for this toolholder.\u003c\/p\u003e\u003cp\u003eThis collet chuck is suited for production machining environments using CAT40-spindle CNC mills and machining centers. The ER11 collet series accommodates small-diameter tooling, making this chuck well-matched for drilling, reaming, and light milling operations where compact nose diameter and high rotational accuracy are required. The 0.7480-inch nose diameter supports use in tight-clearance setups. The through-coolant design is especially relevant in applications involving deep holes or materials that generate significant heat at the cutting edge.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER11 collet system for precise small-diameter tool clamping\u003c\/li\u003e\n\u003cli\u003eCAT40 taper shank for direct mounting to standard CAT40 spindles\u003c\/li\u003e\n\u003cli\u003eBalanced to 18,000 RPM for high-speed machining compatibility\u003c\/li\u003e\n\u003cli\u003eThrough-coolant support via through-spindle and DIN flange coolant paths\u003c\/li\u003e\n\u003cli\u003e2.7559-inch projection for controlled tool reach\u003c\/li\u003e\n\u003cli\u003eNose diameter of 0.7480 inches for clearance in confined workpiece geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT40-spindle CNC machining centers that support ER11 collet toolholders with through-spindle or DIN flange coolant delivery.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before installing or removing the toolholder. Use a calibrated torque wrench with the appropriate ER11 collet nut spanner to secure the collet nut — do not overtighten by hand. Verify spindle taper cleanliness and inspect the CAT40 interface for debris or damage before seating the chuck.\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: ER11\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\u003eProjection\u003c\/strong\u003e: 2.7559 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.4488 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.7480 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 18,000 RPM\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\u003ePackage Dimensions\u003c\/strong\u003e: 6.69 inches L x 2.88 inches W x 2.88 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112808\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6074003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727338766642,"sku":"6074003","price":245.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acf85d4bd0806504cadbe9212561a0a5.jpg?v=1788676497","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6074003-er-collet-chuck-cat40-er11","provider":"Voomi Supply","version":"1.0","type":"link"}
