It accepts the ER40 collet series and features through-coolant capability to direct fluid directly to the cutting zone, improving chip evacuation and tool life. The chuck projects 2.5591 inches from the modular connection interface, with an overall length of 4.0551 inches and a nose diameter of 2.4803 inches. The C6 modular connection size ensures rigid, repeatable coupling to compatible tooling systems. Actuation is performed with a standard wrench. The assembly is balanced to 20,000 RPM, making it suitable for high-speed machining operations where vibration control is critical.\u003c\/p\u003e\u003cp\u003eThis collet chuck is used in CNC machining centers running high-speed milling, drilling, or reaming operations that require consistent tool runout and active coolant delivery. The ER40 collet range accommodates a wide span of tool shank diameters, making this chuck a versatile station in both production and job-shop environments. The C6 modular connection is a common interface on machines and toolholding systems that support Sandvik Coromant modular tooling platforms. Installation is typically performed by a machinist or toolroom technician setting up a live-tool or spindle station.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER40 collet system for broad tool shank diameter range\u003c\/li\u003e\n\u003cli\u003eC6 modular connection shank for rigid, repeatable coupling\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability for direct cutting-zone fluid delivery\u003c\/li\u003e\n\u003cli\u003eBalanced to 20,000 RPM for high-speed machining stability\u003c\/li\u003e\n\u003cli\u003e2.5591-inch projection with 4.0551-inch overall length\u003c\/li\u003e\n\u003cli\u003eWrench-actuated collet clamping for controlled torque application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER40 collets and compatible with tooling systems that accept a C6 modular connection interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist or toolroom technician with the spindle fully stopped and machine power isolated per shop lockout\/tagout procedures. Use the correct ER40 collet nut wrench and collet clamping torque procedures per the machine tool manufacturer guidelines. Verify through-coolant passage alignment and sealing before returning the assembly to service. Inspect the modular connection interface for debris or damage before mounting.\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: ER40\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: C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.5591 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0551 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2.4803 inches\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\u003eBalance Speed\u003c\/strong\u003e: 20,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.7 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: 5730055\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51730635358514,"sku":"5730055","price":705.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5618e44fa24c10ffb934ff81b5fe865a.jpg?v=1788720619","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730055-er40-collet-chuck-c6-modular","provider":"Voomi Supply","version":"1.0","type":"link"}
