It accepts ER11 collets with a clamping range of 0.5 mm to 7 mm (0.0197 to 0.2756 inches), making it well suited for small-diameter end mills, drills, and reamers. The chuck delivers a TIR of 0.0002 inches and is balanced to 25,000 RPM, supporting high-speed machining applications where runout control is critical. Through-spindle coolant capability routes coolant directly through the tool for effective chip evacuation and extended tool life. Installation and setup are performed by machinists or tool crib technicians using a standard ER collet wrench.\u003c\/p\u003e\n\u003cp\u003eThis chuck is intended for use in CAT40-spindle vertical and horizontal machining centers running ER11 tooling. The 4-inch projection and 0.75-inch nose diameter make it practical for operations requiring reach into deep features or confined workpiece geometries. The through-coolant design is particularly useful in drilling and reaming cycles where directed coolant delivery improves hole quality and tool longevity. Wrench actuation provides consistent collet engagement with standard ER11 collet nuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER11 collet system accepts 0.5 mm to 7 mm diameter tooling\u003c\/li\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting in CAT40 spindles\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches for high-precision runout control\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for high-speed machining compatibility\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant delivery for directed coolant flow at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e4-inch projection with 0.75-inch nose diameter for reach in confined setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT40 spindle machining centers and standard ER11 collets.

Power down and lock out the spindle drive before handling the toolholder. Use a calibrated torque wrench and the appropriate ER collet nut spanner to seat the collet nut to the manufacturer-specified engagement  -  do not use impact tools on the collet nut. Verify TIR at the tool tip with a dial test indicator after every toolholder change to confirm seating integrity.\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: 0.50 mm (0.0197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 7.00 mm (0.2756 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: 6.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.75 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\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 25,000 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\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: 3 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: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C40-11ERF400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52056146542898,"sku":"C40-11ERF400","price":168.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20854529bd3a3b38e52eaca5e3759312.jpg?v=1790038065","url":"https:\/\/voomisupply.com\/products\/parlec-c40-11erf400-er11-collet-chuck-cat40-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
