It accepts ER32 series collets with a clamping range of 2 mm to 20 mm, covering a wide variety of end mills, drills, and other cutting tools. The chuck features a straight shank with a 25 mm shank diameter and delivers a total indicator runout (TIR) of 0.0002 inches (0.005 mm), making it suitable for applications where concentricity is critical. Through-coolant capability allows coolant delivery directly to the cutting zone, extending tool life and improving chip evacuation. This chuck is installed by machinists and toolroom technicians using a standard ER32 wrench actuator.\u003c\/p\u003e\u003cp\u003eThe ISCAR 4508004 is well suited for production and job-shop environments running general-purpose machining operations on ferrous and non-ferrous materials. The straight shank design is compatible with machine spindles and toolholding blocks configured for straight-shank chucks at 25 mm diameter. The through-coolant feature makes it a practical choice for deep-hole drilling, high-speed milling, and operations where external coolant delivery is insufficient. Typical users include CNC machinists, setup technicians, and toolroom personnel in both job shops and production facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 collet system with a clamping range of 2 mm to 20 mm (0.0787 to 0.7874 inches)\u003c\/li\u003e\n\u003cli\u003eLow TIR of 0.0002 inches (0.005 mm) for high-concentricity tool holding\u003c\/li\u003e\n\u003cli\u003eThrough-coolant via through-spindle coolant delivery for direct cutting zone coverage\u003c\/li\u003e\n\u003cli\u003eStraight shank at 25 mm diameter and 50 mm shank length for broad machine compatibility\u003c\/li\u003e\n\u003cli\u003eOverall length of 4.0157 inches (102 mm) with a 2.0472-inch (52 mm) projection\u003c\/li\u003e\n\u003cli\u003eWrench-actuated clamping using standard ER32 locknut wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style ER32 collet chuck replacement for machine spindles and toolholding systems configured to accept a straight shank at 25 mm diameter.

Always power down and lock out the machine spindle before changing or seating a collet chuck. Use the correct ER32 torque wrench or spanner wrench to tighten the locknut to the collet manufacturer's recommended procedure — do not use improvised tools that could damage the locknut or collet taper. Verify runout with a dial indicator after installation before returning the machine to production cuts.\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: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.9843 inches (25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.0787 inches (2 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.7874 inches (20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0157 inches (102 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.0472 inches (52 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.9685 inches (50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches (0.005 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes — Through-Spindle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.117 pounds\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: 4508004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728590045490,"sku":"4508004","price":195.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/761955b7aa98c036a32e48a787c4f329.jpg?v=1788693714","url":"https:\/\/voomisupply.com\/products\/iscar-4508004-er32-collet-chuck-25mm-straight-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
