It carries manufacturer grade 4415, a designation engineered for general steel turning with strong resistance to flank wear and built-up edge. The insert features an 80-degree diamond shape, a 0.79 mm corner radius, and a 9.53 mm inscribed circle. The PM chip breaker geometry is designed to manage chip flow reliably across a range of depths of cut and feed rates. Installation is neutral-hand, making it interchangeable across left- and right-hand toolholders designed for the CCMT insert style.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external and internal turning operations on steel and cast iron workpieces in production and job-shop environments. The grade 4415 CVD coating performs well in continuous-cut and light-interrupted-cut conditions on low-alloy and medium-alloy steels, as well as gray and nodular cast iron. It fits toolholders that accept CCMT 09T3 inserts with clamp or screw holding, making it applicable to a wide range of CNC lathes and manual turning centers in both light and medium-duty material removal applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN plus Al2O3 plus TiN for wear resistance and thermal barrier performance\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry for controlled chip evacuation in steel and cast iron turning\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape provides a strong cutting edge angle for general-purpose turning\u003c\/li\u003e\n\u003cli\u003e0.79 mm corner radius balances surface finish quality with edge strength\u003c\/li\u003e\n\u003cli\u003eNeutral-hand orientation fits both left- and right-hand CCMT-compatible toolholders\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; indexed by clamp or screw holding method\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for toolholders that accept CCMT 09T3 inserts using clamp or screw holding.

Use the correct torque wrench and manufacturer-specified seating hardware for the toolholder to avoid insert rocking or premature edge failure. Inspect the insert pocket and shim for wear or debris before seating a new insert. Follow the toolholder manufacturer guidelines for clamping force when using the screw-hold method.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Diamond (80-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\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, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.79 mm (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (0.1732 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3.97 mm (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 09 T3 08-PM 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches (L) x 1.54 inches (W) x 0.43 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 7858989\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749163598130,"sku":"7858989","price":221.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28c9430d43e17b61805bf294c76b621f_4065b65e-19bc-4f3f-aae4-794cdfa9584a.jpg?v=1788902826","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7858989-turning-insert-ccmt32-52-pm","provider":"Voomi Supply","version":"1.0","type":"link"}
