It carries a multilayer CVD coating of TiC, TiCN, and TiN, which improves wear resistance and extends cutting life on demanding materials. The insert features an 80-degree diamond shape with a 0.25-inch inscribed circle and a 1\/32-inch corner radius. Grade TP40 targets steel and stainless steel applications. With two cutting edges and an F2 chip breaker geometry, it suits moderate to heavier roughing and semi-finishing passes on CNC lathes and turning centers. Installation and tool changes are handled by CNC machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production turning of steel and stainless steel workpieces in both roughing and semi-finishing applications. The F2 chip breaker geometry promotes controlled chip formation across a range of depths of cut up to 0.2244 inches. Its positive rake geometry reduces cutting forces, making it a practical choice for medium-duty operations on general-purpose lathes and CNC turning centers. Multi-use capability spans turning, facing, and boring, allowing a single insert to handle several operations within the same setup. The neutral hand orientation accommodates standard right-hand toolholders common in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating (TiC, TiCN, TiN) for improved wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003eF2 chip breaker geometry for controlled chip evacuation in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eGrade TP40 rated for P40 steel and M35\/M40 stainless steel material groups\u003c\/li\u003e\n\u003cli\u003ePositive rake, honed cutting edge reduces cutting forces and minimizes workpiece deflection\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eScrew-lock insert holding compatible with standard CCMT toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for standard CCMT toolholders accepting an 80-degree diamond insert with a 0.25-inch inscribed circle and screw-lock clamping.

Use the appropriate Torx or hex key as specified by the toolholder manufacturer to seat and torque the clamping screw — do not overtighten, as this can crack the insert or damage the toolholder pocket. Inspect the pocket and screw for debris or wear before seating a new insert. This insert is intended for installation by qualified CNC machinists or toolroom personnel familiar with indexable tooling systems.\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\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT21.52-F2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT060208-F2\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\u003eManufacturer Grade\u003c\/strong\u003e: TP40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P40, M35, M40\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: TiC, TiCN, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD Multilayer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: F2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0937 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: 0.2244 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 74018654\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557864210738,"sku":"74018654","price":170.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2711eeb96b575057436972afa66c8a9.jpg?v=1786396757","url":"https:\/\/voomisupply.com\/products\/seco-74018654-turning-insert-ccmt21-52-f2-tp40-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
