It accepts ER32 series collets with a clamping capacity range of 0.08 to 0.789 inches, covering a broad range of round shanks. The chuck delivers a total indicator runout (TIR) of 0.0001 inches, making it suitable for finish milling, drilling, and reaming operations where concentricity matters. A 1.124-inch projection positions the collet nose close to the spindle face, reducing overhang. Through-coolant capability supports both through-spindle and DIN flange coolant delivery. Balanced to 20,000 RPM, this chuck is appropriate for high-speed machining environments.\u003c\/p\u003e\n\u003cp\u003eThe 4501600 is used in vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. It is a common choice for production shops and toolrooms running high-speed cutting operations where runout control and coolant delivery are required at the spindle. The ER32 collet system is a widely adopted standard, and this chuck is suited to facilities that have already standardized on ER32 tooling across their workholding inventory. Licensed machinists and CNC setup technicians are the primary installers and operators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER32 collet system with 0.08 to 0.789 inches clamping capacity range\u003c\/li\u003e\n  \u003cli\u003eCAT40 taper shank for compatibility with standard CNC machining center spindles\u003c\/li\u003e\n  \u003cli\u003e0.0001 inches TIR for high-precision concentricity in finishing operations\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design supporting through-spindle and DIN flange coolant delivery\u003c\/li\u003e\n  \u003cli\u003eBalanced to 20,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003e1.124-inch projection minimizes tool overhang from the spindle face\u003c\/li\u003e\n  \u003cli\u003e1.575-inch nose diameter for ER32 collet nut engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers with a CAT40 taper spindle interface.

Use a proper ER32 collet wrench and spanner to torque the collet nut to the collet manufacturer specifications — do not use substitutes that could damage the nut or collet taper. Inspect the CAT40 taper and spindle bore for chips or burrs before seating the chuck. Verify TIR with a dial indicator after installation before beginning any cutting 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: 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: 1.124 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4501600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737428263218,"sku":"4501600","price":310.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ed8c698c0c1e5fbd719e11ad3beee0d_f64aadd7-cc1b-43f1-9b13-e718c6d74e75.jpg?v=1788788428","url":"https:\/\/voomisupply.com\/products\/iscar-4501600-er32-collet-chuck-cat40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
