It features a diamond 80-degree insert shape with a 7-degree relief angle and an M3 chip breaker geometry that controls chips effectively across a range of feed rates and depths of cut. The insert carries a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — that enhances wear resistance and thermal stability. With a 0.25-inch inscribed circle and a 0.0315-inch corner radius, it suits moderate to light finishing and medium roughing passes. Two cutting edges per insert are available, and the screw-lock holding method provides rigid clamping in compatible toolholders. Licensed machinists and CNC operators install this insert in production turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is rated primarily for steel (ISO material code P) and is also suitable for stainless steel (M) and cast iron (K). It is applicable to boring, facing, and turning operations. The positive rake geometry reduces cutting forces, making it well-suited for workpieces in the P10 through P35 material grade range. The chamfered and honed cutting edge style supports a stable edge line and consistent surface finish. Maximum depth of cut is 0.2205 inches, and insert length is 0.2559 inches, placing it in a compact size class for lighter tooling setups on both manual and CNC lathes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended tool life in steel and stainless applications\u003c\/li\u003e\n\u003cli\u003eM3 chip breaker geometry supports boring, facing, and turning across medium feed ranges\u003c\/li\u003e\n\u003cli\u003ePositive rake, chamfered and honed cutting edge reduces cutting forces and improves edge stability\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert for cost-efficient use\u003c\/li\u003e\n\u003cli\u003eScrew-lock holding method for secure, repeatable seating in CCMT-compatible toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards with ISO code CCMT060208-M3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production insert for CCMT-style screw-lock toolholders conforming to ANSI and ISO CCMT060208-M3 specifications.

Use the appropriate Torx or hex key specified by the toolholder manufacturer to secure the clamping screw — do not over-tighten, as carbide inserts are brittle and can crack under excessive clamp load. Inspect the insert pocket seat and shim for debris or damage before seating a new insert. Follow shop safety protocols and applicable OSHA machine guarding requirements when servicing CNC turning centers or manual lathes.\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\u003eSeries\u003c\/strong\u003e: CCMT-M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT21.52-M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT060208-M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP2501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P10, P20, P30, P35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2559 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1142 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2205 inches\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\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02960846\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558045942066,"sku":"02960846","price":176.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f63bd68f3603f70f891c36fbeefdbfa4.jpg?v=1786401812","url":"https:\/\/voomisupply.com\/products\/seco-02960846-turning-insert-ccmt21-52-m3-tp2501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
