It accepts the ER32 collet series and mounts via a C6 modular connection shank, making it compatible with machine tool interfaces that use the C6 modular standard. The chuck features a 3.937-inch projection and an overall length of 5.433 inches. Through-coolant capability delivers cutting fluid directly to the tool tip, supporting higher cutting speeds and longer tool life. Actuation is by wrench. This chuck is balanced to 20,000 RPM, making it suitable for high-speed machining applications where runout and dynamic balance are critical.\u003c\/p\u003e\u003cp\u003eThis collet chuck is used in CNC machining centers and turning centers equipped with C6 modular connection interfaces. It is suited for milling, drilling, reaming, and tapping operations where ER32 collets are the preferred workholding method. The through-coolant design makes it a practical choice for deep-hole drilling and high-speed finishing passes where chip evacuation and heat management matter. Machinists and toolroom technicians working in aerospace, automotive, and general metalworking environments will find this chuck appropriate for both roughing and finishing tool configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 collet system accepts a wide range of ER32 collet bore sizes\u003c\/li\u003e\n\u003cli\u003eC6 modular connection shank for compatibility with C6 modular tooling interfaces\u003c\/li\u003e\n\u003cli\u003e3.937-inch projection provides clearance for workpiece features and fixturing\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design directs fluid to the cutting zone for chip control and heat reduction\u003c\/li\u003e\n\u003cli\u003eBalanced to 20,000 RPM for high-speed spindle applications\u003c\/li\u003e\n\u003cli\u003eWrench actuation for secure collet clamping and repeatable tool setting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with machine tool spindles and turrets equipped with a C6 modular connection interface.

Power down and lock out the machine spindle before mounting or removing the chuck. Ensure the C6 modular connection and mating interface are clean and free of chips or burrs before assembly. Torque the collet nut using the appropriate ER32 wrench to the tool manufacturer's specifications, and verify runout with a dial indicator before running at elevated spindle speeds.\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: C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3.937 inches (100.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.433 inches (138.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.969 inches (50.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Balanced Speed\u003c\/strong\u003e: 20,000 RPM\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: 3.53 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: 5730129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749851693362,"sku":"5730129","price":711.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23f808e13f048981c57dbbcf52ea7125_80003a55-4c80-4456-904a-39bb1c53f588.jpg?v=1788911265","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730129-er32-collet-chuck-c6-modular","provider":"Voomi Supply","version":"1.0","type":"link"}
