This adapter features a 2.4803-inch (63 mm) bore diameter and a bore depth of 4.8425 inches (123 mm), providing rigid, accurate coupling between modular boring heads and compatible tool bodies. The C6 connection size enables repeatable positioning and secure assembly. Internal coolant delivery directs cutting fluid directly to the cutting zone, supporting longer tool life and improved chip evacuation during deep-bore operations. This part is installed by machinists and toolroom technicians working on CNC lathes and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis modular adapter suits precision boring applications in manufacturing environments where consistent bore geometry and surface finish are required. It is configured for internal coolant routing, making it appropriate for deep-bore and production-run scenarios where heat management is critical. The adapter accepts compatible lock screws and coolant screws as specified, allowing integration into standard modular tooling setups. Typical users include CNC machinists, tool-and-die professionals, and production tooling specialists working with modular boring systems in job shop or production floor settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC6 connection size for rigid, repeatable modular tooling assembly\u003c\/li\u003e\n  \u003cli\u003e2.4803-inch (63 mm) bore diameter with 4.8425-inch (123 mm) bore depth\u003c\/li\u003e\n  \u003cli\u003eInternal coolant delivery channel for heat control and chip evacuation at the cutting zone\u003c\/li\u003e\n  \u003cli\u003eLock screw compatibility with 3214 020-512 for secure clamping\u003c\/li\u003e\n  \u003cli\u003eCoolant screw compatibility with 5691 034-02\u003c\/li\u003e\n  \u003cli\u003eBody length of 4.8425 inches (123 mm) supports deep-bore reach\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with modular boring bar systems using C6 connection size.

Ensure the machine spindle is fully stopped and all stored energy is released before assembling or disassembling modular components. Use only the specified compatible lock screws and coolant screws; substituting fasteners can compromise clamping integrity and internal coolant sealing. Verify coolant line connections are properly seated and leak-free before returning the tool to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 2.4803 inches (63 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 4.8425 inches (123 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 2.4803 inches (63 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 4.8425 inches (123 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Size\u003c\/strong\u003e: 5.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: 3214 020-512\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Screw Compatibility\u003c\/strong\u003e: 5691 034-02\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.33 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.59 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5728789\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51746178728242,"sku":"5728789","price":2156.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a10f184012bed89a35e926a12caed7c.jpg?v=1788866797","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5728789-boring-bar-modular-adapter-c6","provider":"Voomi Supply","version":"1.0","type":"link"}
