It accepts ER11 collets with a capacity range of 0.019 to 0.275 inches, making it suitable for small-diameter end mills, drills, and reamers. The chuck features a 6-inch projection and a total indicator runout (TIR) of 0.0002 inches, which supports tight-tolerance work. It is balanced to 30,000 RPM and includes through-coolant capability, allowing coolant to reach the cutting zone directly through the spindle and DIN flange. Licensed machinists and CNC setup technicians are the primary users of this toolholder.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is suited for use on CAT40-spindle vertical and horizontal machining centers in both production and job-shop environments. The ER11 collet series is commonly used when machining small-bore features in aluminum, steel, and other materials where secure clamping and minimal runout are critical. The through-coolant design is especially useful in deep-hole drilling and high-speed finishing operations where heat management and chip evacuation matter. The 6-inch projection accommodates reach requirements in fixture-heavy or deep-cavity setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER11 collet system with 0.019 to 0.275 inch capacity range for small-diameter tooling\u003c\/li\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting on standard CAT40 machining center spindles\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch TIR for high-precision, low-runout tool holding\u003c\/li\u003e\n  \u003cli\u003eBalanced to 30,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant compatible via through-spindle and DIN flange coolant delivery\u003c\/li\u003e\n  \u003cli\u003e6-inch projection provides extended reach for deep-cavity and fixtured workpiece setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT40-spindle CNC machining centers that support ER11 collet toolholders.

Power down and lock out the machining center spindle before mounting or removing the toolholder. Use a properly rated CAT40 pull stud and torque the collet nut with a calibrated ER collet wrench to manufacturer specifications. Inspect the taper shank and spindle bore for contamination or damage before seating the chuck.\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: 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\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.019 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 0.75 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\u003eBalanced To\u003c\/strong\u003e: 30,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 775634\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51972809228594,"sku":"775634","price":181.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c27d32054d9fd671d72702ce67133d9.jpg?v=1789970769","url":"https:\/\/voomisupply.com\/products\/accupro-775634-er11-cat40-collet-chuck-6-in-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
