It accepts a 0.75-inch bore diameter and features an internal coolant delivery channel that directs fluid directly to the cutting zone, reducing heat buildup and extending insert life. The adapter uses a C4 connection size and a lock screw with a 1.02-inch seating diameter for secure, repeatable tool engagement. The body diameter measures 1.5748 inches with a body length of 0.9843 inches. This component is installed by machinists and tooling specialists setting up modular boring systems for high-tolerance internal machining work.\u003c\/p\u003e\n\u003cp\u003eThis adapter fits into modular quick-change tooling systems that use a C4 interface, common in production turning cells and machining centers requiring frequent tool changes without sacrificing rigidity or runout accuracy. The internal coolant port supports high-pressure coolant delivery, making it suitable for deep-bore finishing operations, difficult-to-machine alloys, and applications where chip evacuation is critical. Bore depth capacity is 0.9843 inches. It is well-suited for both horizontal and vertical machining center setups where modular tooling reduces changeover time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.75-inch bore diameter for precise tool coupling in modular boring systems\u003c\/li\u003e\n  \u003cli\u003eInternal coolant channel for directed cutting zone cooling and chip control\u003c\/li\u003e\n  \u003cli\u003eC4 connection size for compatibility with standard modular quick-change tooling interfaces\u003c\/li\u003e\n  \u003cli\u003e1.02-inch lock screw seating diameter for rigid, repeatable tool clamping\u003c\/li\u003e\n  \u003cli\u003eBody diameter of 1.5748 inches and body length of 0.9843 inches for compact installation clearance\u003c\/li\u003e\n  \u003cli\u003eCompatible lock screw: 3212 010-207\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with modular tooling systems using a C4 connection interface.

Power down and lock out the machine spindle before mounting or removing any modular tooling adapter. Verify that the lock screw is seated properly and that the C4 connection interface is free of chips or debris before torquing. Confirm internal coolant passages are clear and aligned with the machine coolant supply port prior to operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1.5748 inches (40.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Size\u003c\/strong\u003e: 1.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Lock Screw\u003c\/strong\u003e: 3212 010-207\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.87 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: 6228916\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731818053938,"sku":"6228916","price":645.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb016fa24f7ba286d056286d3b8bd0af_a9e9a7c6-a798-4c8f-8c0c-629b9140a14a.jpg?v=1788735265","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6228916-boring-bar-modular-adapter-0-75-in","provider":"Voomi Supply","version":"1.0","type":"link"}
