It accepts ER16 collets with a capacity range of 0.50 mm to 10.00 mm (0.0197 to 0.3937 inches), covering a wide range of small-diameter cutting tools. The chuck features a 2.5 inch projection from gauge line to nose, an overall length of 5.19 inches, and a total indicated runout (TIR) of 0.0002 inches for tight tolerancing on finish and drilling operations. Through-spindle coolant delivery is supported, directing coolant directly to the cutting zone. This toolholder is installed and set up by machinists and CNC setup technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis chuck is suited for vertical and horizontal machining centers equipped with CAT40 spindles. It is commonly used in applications requiring small-diameter end mills, drills, reamers, or taps held in ER16 collets. The through coolant feature makes it a strong choice for deep-hole drilling, high-speed finishing, and operations on materials that generate significant heat at the cutting edge. The chuck is balanced to 25,000 RPM, supporting high-speed machining strategies on modern CNC equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet system accepts tools from 0.50 mm to 10.00 mm in diameter\u003c\/li\u003e\n  \u003cli\u003eCAT40 taper shank for direct spindle mounting on standard machining centers\u003c\/li\u003e\n  \u003cli\u003e2.5 inch projection provides clearance for workpiece fixturing in typical setups\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches supports precision boring, reaming, and finishing passes\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant delivery directs fluid to the cutting zone via compatible ER coolant collets\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003eWrench-actuated collet nut for secure, repeatable tool clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT40 spindle machines and ER16 coolant collets.

Power down and lock out the machining center before changing toolholders. Use the correct ER16 collet wrench and spanner to seat and torque the collet nut; do not use substitute tools that may damage the nut or collet taper. Verify TIR at setup with a dial indicator to confirm the collet is fully seated before running at speed.\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\u003eProjection\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.19 inches\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\u003eTIR\u003c\/strong\u003e: 0.0002 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\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 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: C40-16ERF250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52039913832754,"sku":"C40-16ERF250","price":186.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b16296a8f5097d0468ce454509328db.jpg?v=1790026586","url":"https:\/\/voomisupply.com\/products\/parlec-c40-16erf250-er16-collet-chuck-cat40-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
