It features a C8 modular connection size and a projection of 2.7559 inches, providing the reach needed for a wide range of milling and drilling operations. Through-coolant capability directs cutting fluid to the tool tip, supporting chip evacuation and thermal control at higher speeds. The chuck is balanced to 14,000 RPM, making it suitable for high-speed machining applications where runout and vibration must be minimized. Licensed machinists and CNC setup technicians install this chuck as part of a modular tooling system.\u003c\/p\u003e\u003cp\u003eThis collet chuck is intended for use in shop environments running modular tooling systems with C8-size connections. It accepts ER32 collets, which cover a broad range of tool shank diameters commonly used in production milling, drilling, reaming, and tapping. The overall length of 4.6457 inches and a nose diameter of 1.9685 inches suit medium-duty machining setups where clearance and reach are key considerations. Typical installation scenarios include horizontal and vertical machining centers in both job-shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 collet system accepts a wide range of tool shank diameters for versatile toolholding\u003c\/li\u003e\n\u003cli\u003eC8 modular connection shank integrates directly into modular tooling interfaces without a separate adapter\u003c\/li\u003e\n\u003cli\u003e2.7559 inches projection provides extended reach for deep-cavity or obstructed-access machining\u003c\/li\u003e\n\u003cli\u003eBalanced to 14,000 RPM for stable high-speed operation with reduced vibration\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design channels cutting fluid directly to the cutting zone\u003c\/li\u003e\n\u003cli\u003eWrench actuator type for straightforward collet tightening and release\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER32 collets and modular tooling systems utilizing a C8 modular connection interface.

Ensure the machine spindle and modular interface are fully de-energized and at rest before mounting or removing the chuck. Clean mating surfaces on both the chuck and the modular connection before assembly to ensure proper seating and runout performance. Follow the machine tool manufacturer torque guidelines for the specific modular connection interface when securing the chuck.\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: 2.7559 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.6457 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.9685 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced Speed\u003c\/strong\u003e: 14,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.2 inches L x 4.13 inches W x 3.74 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.7 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: 5729381\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51754044784946,"sku":"5729381","price":775.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23f808e13f048981c57dbbcf52ea7125_dd71ea45-c7b4-48b8-aa48-b7a2c74f892d.jpg?v=1788943151","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5729381-er32-collet-chuck-c8-modular-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
