Carrying grade designation TP2501, this insert is engineered for moderate to heavy-duty turning operations on steel and stainless steel. The negative rake geometry, 0-degree relief angle (Clearance Code N), and chamfered-and-honed cutting edge work together to manage heat and mechanical load during interrupted or continuous cuts. Six usable cutting edges per insert keep tooling cost per edge competitive in production environments. Installed by machinists and CNC tooling technicians, this insert fits standard TNMG-compatible toolholders using clamp, pin, or lever-lock holding methods.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external turning, facing, boring, and back turning operations on CNC lathes and turning centers. Primary workpiece material is steel (ISO P), with rated secondary applications in stainless steel (ISO M) and cast iron (ISO K). Material grade classifications P10, P20, P30, and P35 cover a broad range of steel types from finishing to roughing cuts. The M3 chip breaker geometry supports medium-depth cuts and helps maintain chip control across varying feed rates. Maximum depth of cut reaches 0.5354 inches, giving the insert flexibility across roughing and semi-finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for heat resistance and wear life in steel cutting\u003c\/li\u003e\n\u003cli\u003e6 cutting edges per insert — multi-tipped geometry reduces cost per edge\u003c\/li\u003e\n\u003cli\u003eM3 chip breaker for reliable chip control in medium-depth turning applications\u003c\/li\u003e\n\u003cli\u003eNegative rake, chamfered-and-honed edge for strength on interrupted and continuous cuts\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever-lock toolholder holding methods\u003c\/li\u003e\n\u003cli\u003eRated for back turning, boring, facing, and turning — broad multi-use application range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMG-style toolholders accepting a 3\/8-inch inscribed circle, 3\/16-inch thick triangular insert with a 0-degree clearance angle (N).

Seat the insert fully against the toolholder pocket and apply clamping force according to the toolholder manufacturer specifications — do not overtighten clamp screws by feel alone, as this can chip the cutting edge. Inspect the seating pocket for chips or debris before installing a new edge or indexing to the next edge. Follow shop-standard lockout and tagout procedures before performing any insert change at the machine.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TNMG-M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TNMG333-M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG160412-M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP2501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code)\u003c\/strong\u003e: 0 degrees (N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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\u003eChip Breaker\u003c\/strong\u003e: M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN, Al2O3, Cr (Duratomic CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6496 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0472 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5354 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\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), Cast Iron (ISO K)\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\u003eMulti-Use Application\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 02959984\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561951166770,"sku":"02959984","price":224.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28092ef9c959ada99008eaefd8b0a8e2_6fa234e1-3af5-4c13-99f9-d7cf27f9ac88.jpg?v=1786470226","url":"https:\/\/voomisupply.com\/products\/seco-02959984-turning-insert-tnmg333-m3-tp2501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
