It accepts ER16 collets with a clamping range of 0.5 mm to 10 mm (0.0197 to 0.3937 inches) and delivers a total indicator runout (TIR) of 0.0002 inches for tight tolerances on finish milling, drilling, and reaming operations. A 4-inch projection length provides clearance for deep-pocket and complex-geometry work. The chuck is balanced to 25,000 RPM, making it suitable for high-speed machining applications. Installation and setup are performed by CNC machinists and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is used in vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. The 4-inch projection suits setups where additional reach is needed to clear fixtures, vises, or part features without sacrificing rigidity. Through-spindle coolant delivery is supported, directing coolant directly through the toolholder to the cutting zone. This is particularly useful in deep-hole drilling, high-speed milling, and applications where chip evacuation and heat management are critical. The actuator type is wrench-driven, which is standard for ER collet nut tightening on the shop floor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet system with clamping range of 0.5 mm to 10 mm\u003c\/li\u003e\n  \u003cli\u003eCAT40 taper shank for direct spindle mounting on CAT40 machining centers\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches for precision runout control\u003c\/li\u003e\n  \u003cli\u003e4-inch projection for extended reach in deep-pocket applications\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant capable, directing coolant to the cutting tool\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for high-speed machining compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers with a CAT40 spindle interface.

Ensure the machine spindle is fully stopped and the tool changer is disengaged before mounting or removing the toolholder. Clean the CAT40 taper and spindle bore thoroughly before seating the chuck to prevent runout errors caused by chips or contamination. Torque the retention knob and collet nut according to the machine tool manufacturer and toolholder manufacturer specifications using the appropriate ER16 spanner wrench and torque wrench.\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: 0.50 mm (0.0197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 10.00 mm (0.3937 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: 1.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 1.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 25,000 RPM\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: C40-16ERF400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52011354063154,"sku":"C40-16ERF400","price":188.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e1114842f0f793ab5e29197fefb7bbd.jpg?v=1790004597","url":"https:\/\/voomisupply.com\/products\/parlec-c40-16erf400-er16-collet-chuck-cat40-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
