It accepts ER32 collets with a clamping range of 0.08 to 0.789 inches, providing a broad range of tool holding capacity in a single chuck body. The chuck features a 1.754-inch projection and a nose diameter of 1.575 inches. Total indicator runout (TIR) is rated at 0.0001 inches, making it suitable for precision milling, drilling, and boring operations. Through-coolant capability is supported via both through-spindle and DIN flange coolant delivery.\u003c\/p\u003e\u003cp\u003eThis collet chuck is intended for use in production and job-shop CNC milling environments requiring reliable tool retention and coolant delivery at the cutting edge. It is balanced to 20,000 RPM, making it appropriate for high-speed machining applications. Installation and tool changes are performed by CNC machine operators and setup technicians. The ER32 collet system is widely used across light to medium-duty machining tasks including end milling, reaming, and tapping.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 collet system with 0.08 to 0.789 inch clamping range\u003c\/li\u003e\n\u003cli\u003eCAT40 taper shank for direct spindle mounting on compatible machining centers\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0001 inches for high-precision tool holding\u003c\/li\u003e\n\u003cli\u003eThrough-coolant support via through-spindle and DIN flange delivery\u003c\/li\u003e\n\u003cli\u003eBalanced to 20,000 RPM for high-speed machining compatibility\u003c\/li\u003e\n\u003cli\u003e1.754-inch projection with 1.575-inch nose diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER32 collets in CAT40 taper shank spindle machines.

Power down and lock out the machine spindle before mounting or removing the chuck. Use the appropriate spanner wrenches and torque procedures specified by the machine tool manufacturer when seating the CAT40 taper and tightening the collet nut. Verify TIR with a dial indicator after installation before beginning cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: ER32\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: 0.08 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.789 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1.754 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.575 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0001 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 and DIN Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 20,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4501656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737167659314,"sku":"4501656","price":301.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ed8c698c0c1e5fbd719e11ad3beee0d.jpg?v=1788785159","url":"https:\/\/voomisupply.com\/products\/iscar-4501656-er32-collet-chuck-cat40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
