Built on a C8 modular interface, it delivers a 6.2992-inch projection and an overall length of 8.189 inches, making it well-suited for applications requiring extended reach while maintaining rigidity. The chuck is balanced to 14,000 RPM, supporting high-speed machining operations without excessive vibration. Through-coolant capability directs cutting fluid to the tool tip for effective heat management and chip evacuation. Actuation is accomplished with a standard wrench. This toolholder is installed by CNC machinists and toolroom technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis chuck is intended for use in machining centers and CNC turning or milling platforms equipped with a C8 modular connection interface. The ER32 collet system accepts a wide range of collet sizes within the ER32 series, providing flexibility across multiple tooling diameters. It is suited for both roughing and finishing operations where coolant delivery to the cutting zone is a process requirement. The 14,000 RPM balance rating makes it appropriate for high-speed spindle applications in both ferrous and non-ferrous material removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 collet system with C8 modular connection shank interface\u003c\/li\u003e\n\u003cli\u003e6.2992-inch projection for extended reach in deep-cavity or obstructed-access setups\u003c\/li\u003e\n\u003cli\u003eBalanced to 14,000 RPM for high-speed machining compatibility\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design for direct coolant delivery to the cutting edge\u003c\/li\u003e\n\u003cli\u003eWrench-actuated collet clamping for secure and repeatable tool holding\u003c\/li\u003e\n\u003cli\u003eNose diameter of 1.9685 inches for clearance in confined workpiece geometries\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with C8 modular connection tooling systems and ER32 series collets. Specific machine and collet compatibility should be verified against the C8 interface standard and the ER32 collet size range for the intended tooling diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC toolroom technicians or machinists. The spindle must be fully stopped and the machine placed in a safe, locked-out state before mounting or removing the toolholder. Use the appropriate ER32 collet nut wrench and spanner to achieve proper collet seating and clamping force; do not use impact tools on the collet nut. Verify coolant port alignment with the machine spindle coolant supply before operation.\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: Modular Connection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModular Connection Size\u003c\/strong\u003e: C8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 6.2992 inches (160.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.189 inches (208.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalance Rating\u003c\/strong\u003e: 14,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\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: 8.7 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5729382\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727628697906,"sku":"5729382","price":798.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/960b46039a70c2a50ad06761dddd6701.jpg?v=1788680272","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5729382-er32-collet-chuck-c8-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
