It accepts ER40 collets with a capacity range of 3 mm (0.1181 inches) to 30 mm (1.1811 inches), covering a wide range of cutting tool shank diameters. The chuck features a 4-inch projection and delivers a TIR (total indicator runout) of 0.0002 inches, making it suitable for applications where concentricity and repeatability are critical. Through-spindle coolant capability is built in, directing coolant directly to the cutting edge for improved tool life and chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is intended for use in CAT40-spindle machining centers in production and job-shop environments. It is suited for milling, drilling, reaming, and tapping operations where through-coolant delivery and tight runout tolerances are required. The ER40 collet system is a widely adopted standard, and this chuck works with any compliant ER40 collet purchased separately. Licensed machinists, CNC operators, and tooling setup technicians are the typical end users for this type of toolholder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet system accepts tool shanks from 3 mm to 30 mm (0.1181 to 1.1811 inches)\u003c\/li\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting in CAT40 machining center spindles\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches for high concentricity and repeatability\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant delivery routes coolant to the cutting zone\u003c\/li\u003e\n  \u003cli\u003e4-inch projection provides clearance for a range of workpiece and fixture configurations\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for high-speed machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CAT40-spindle CNC machining centers.

Ensure the machine spindle is fully stopped and the tool change cycle is complete before handling the toolholder. Use the correct CAT40 retention knob torque specification supplied by the machine manufacturer. Confirm coolant port alignment with the spindle coolant supply before engaging through-coolant operation.\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: ER40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: CAT40 Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 30 mm (1.1811 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: 20.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 2.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\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\u003c\/strong\u003e: 25,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 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: C40-40ERF400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51971247669554,"sku":"C40-40ERF400","price":176.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d8e9f4a5f4bd9584b51391829791251.jpg?v=1789955076","url":"https:\/\/voomisupply.com\/products\/parlec-c40-40erf400-er40-collet-chuck-cat40-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
