It provides a 2.3622-inch projection and an overall length of 3.8583 inches, making it well suited for applications where precise tool reach and rigidity are required. The chuck is balanced to 20,000 RPM, supporting high-speed machining operations without introducing vibration that could compromise surface finish or tool life. Through-coolant capability allows cutting fluid to be delivered directly to the cutting zone, improving chip evacuation and extending insert life. A licensed machinist or toolroom technician installs this chuck as part of a modular toolholder assembly on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is intended for use in CNC milling and machining center applications where a C6 modular connection interface is present. The ER20 collet system accommodates a standard range of ER20 collets, making it a practical choice for shops running small-diameter end mills, drills, or reamers at elevated spindle speeds. It is suited for both roughing and finishing operations in light to medium-duty cutting conditions where coolant delivery and rotational balance are critical process requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet system accepts standard ER20 collets for versatile tooling options\u003c\/li\u003e\n  \u003cli\u003eC6 modular connection shank integrates directly into compatible modular toolholder systems\u003c\/li\u003e\n  \u003cli\u003eBalanced to 20,000 RPM for stable high-speed spindle performance\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design channels fluid to the cutting edge for improved chip evacuation and tool life\u003c\/li\u003e\n  \u003cli\u003e2.3622-inch projection offers adequate reach for most milling and drilling setups\u003c\/li\u003e\n  \u003cli\u003eWrench-actuated collet nut provides consistent clamping force during tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with C6 modular connection toolholder systems accepting ER20 collet chucks. Compatible with standard ER20 series collets. Confirm C6 interface compatibility with your specific machine spindle or modular block before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with modular toolholding systems. Power down and lock out the machine spindle before mounting or removing the chuck from the modular connection. Use the appropriate ER20 collet nut wrench to achieve proper clamping torque; do not over-tighten by impact methods. Verify runout with a dial indicator after assembly to confirm the chuck is seated correctly before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: ER20\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: 2.3622 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.8583 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.3268 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To\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: 2.21 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 5730112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51743312183602,"sku":"5730112","price":705.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/960b46039a70c2a50ad06761dddd6701_3a717217-937e-46e3-b810-ba587ea1fc64.jpg?v=1788845482","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730112-er20-collet-chuck-c6-modular-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
