It carries a CVD-applied TiCN and TiN coating over a carbide substrate, delivering wear resistance and thermal stability during continuous and light interrupted cuts. The insert features an 80-degree diamond shape, a 1\/4-inch inscribed circle, a 1\/64-inch corner radius, and a UR chip breaker geometry. With two cutting edges per insert and a screw-type holding method, it provides consistent edge repeatability for production turning environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel and stainless steel workpieces in both roughing and finishing passes where controlled chip evacuation is critical. The UR chip breaker geometry is optimized for medium to light depths of cut on steels and austenitic stainless grades. Typical install scenarios include OD turning and facing operations on conventional and live-tooling setups. It is applied by machinists and CNC programmers in job shops, production facilities, and maintenance machine shops working with P-class and M-class ISO workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-coated TiCN and TiN layers for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CCMT) for versatile turning and facing applications\u003c\/li\u003e\n  \u003cli\u003eUR chip breaker geometry optimized for medium to light cuts on P-class and M-class materials\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius for a balance of edge strength and surface finish capability\u003c\/li\u003e\n  \u003cli\u003eScrew-type insert holding for secure, repeatable seating in CoroTurn 107 compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert maximizing cost-per-edge value\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroTurn 107 series toolholders that accept CCMT 06 02 04 inserts.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specified seating torque. Inspect the insert pocket and seating surfaces for chips or debris before installing a new edge to ensure proper contact and prevent insert rocking.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 80-degree Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 235\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and TiN (CVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches \/ 0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2381 inches (6.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0938 inches \/ 2.38 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 06 02 04-UR 235\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 5723684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731829358898,"sku":"5723684","price":222.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d855925875ec908c869e2381c8213f07_321a96f2-dcd4-41b3-a12f-5236fd9ad7a2.jpg?v=1788735400","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5723684-turning-insert-ccmt21-51-ur-235","provider":"Voomi Supply","version":"1.0","type":"link"}
