It accepts ER16 collets with a capacity range of 0.50 mm to 10.00 mm (0.0197 to 0.3937 inches), making it suitable for a wide range of end mills, drills, and reamers within that range. The chuck features a 5.12-inch projection and holds a maximum total indicator runout (TIR) of 0.0002 inches, supporting tight-tolerance work. Through-spindle coolant delivery is built in, directing coolant directly to the cutting zone. The unit is balanced to 25,000 RPM and weighs 3.65 pounds.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is intended for use in CAT40-spindle machining centers in both production and job-shop environments. It is well suited for high-speed milling, drilling, and reaming operations where runout control and coolant-at-the-tip capability are required. The ER16 collet system is a widely adopted standard, and this chuck is actuated with a standard ER wrench. The extended 5.12-inch projection provides clearance for deep-cavity or fixturing-constrained workpieces. Installation and tool changes are performed by licensed machinists or CNC machine operators following the machine tool builder's spindle interface procedures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting in CAT40 machining center spindles\u003c\/li\u003e\n  \u003cli\u003eER16 collet system with capacity range of 0.50 mm to 10.00 mm\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch TIR for high-precision, low-runout tool holding\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant delivery routes coolant directly to the cutting tool\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003e5.12-inch projection accommodates deep-cavity and clearance-critical setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ER16 collet chuck for CAT40-spindle CNC machining centers.

The machine spindle must be fully powered down and the tool changer disabled before mounting or removing the chuck. Use the appropriate CAT40 retention knob and torque the drawbar or toolholder per the machine tool builder's specification. Always use a calibrated runout gauge to verify TIR after seating the chuck before beginning production cuts.\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: 5.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.81 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\u003c\/strong\u003e: 25,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.65 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: C40-16ERP512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51987706937650,"sku":"C40-16ERP512","price":297.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97ff79acf3183426e335135e9176cf60.jpg?v=1789987048","url":"https:\/\/voomisupply.com\/products\/parlec-c40-16erp512-er16-collet-chuck-cat40-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
