It features a 0.9055-inch (23.00 mm) bore diameter and a C4 connection size, making it compatible with C4-standard modular tooling interfaces. The adapter has a body diameter of 0.7874 inches (20.00 mm) and an overall length of 4.1929 inches (106.50 mm). Internal coolant delivery is supported, directing cutting fluid directly to the cutting zone for improved chip evacuation and tool life. This adapter is installed by machinists and tooling specialists in CNC turning and boring operations requiring modular, quick-change tooling setups.\u003c\/p\u003e\u003cp\u003eThis adapter fits into modular boring and turning setups on CNC lathes and machining centers where C4-interface tooling is used. It is suited for both production and job-shop environments where repeatable tool change accuracy is required. The internal coolant path makes it well-suited for deep-bore operations and difficult-to-machine materials where heat management at the cutting edge is critical. The body length of 1.2008 inches (30.50 mm) provides a compact coupling profile that minimizes overhang while maintaining rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eC4 modular connection size for compatibility with C4-standard boring systems\u003c\/li\u003e\n\u003cli\u003eInternal coolant delivery supports chip evacuation and tool life in deep-bore applications\u003c\/li\u003e\n\u003cli\u003e0.9055-inch (23.00 mm) bore diameter for precise tool registration\u003c\/li\u003e\n\u003cli\u003eCompact body length of 1.2008 inches (30.50 mm) reduces overhang and improves rigidity\u003c\/li\u003e\n\u003cli\u003eOverall length of 4.1929 inches (106.50 mm) suits standard CNC tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with C4-interface modular boring and turning tooling systems.

Power down and lock out the machine spindle before mounting or removing any tooling adapter. Ensure all mating surfaces are clean and free of chips or burrs before assembly to maintain interface accuracy. Verify coolant port alignment when connecting internal coolant supply lines to avoid flow restriction.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.9055 inches (23.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.7874 inches (20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.1929 inches (106.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.2008 inches (30.50 mm)\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\u003eType\u003c\/strong\u003e: Boring Adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: 5728216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51782629556530,"sku":"5728216","price":1506.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fb9480e13ac3ec753b3fa6316155bff_df73583d-e941-4e27-a334-d5a73c60123d.jpg?v=1789180002","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5728216-boring-bar-modular-adapter-c4","provider":"Voomi Supply","version":"1.0","type":"link"}
