Identified by ISO code TNMG 22 04 08-PM 4425, this insert features a 60-degree triangular shape with a neutral hand orientation and delivers six usable cutting edges per insert. The CVD-applied multilayer coating stack of Al2O3, TiN, and TiCN provides thermal resistance and wear protection during continuous and interrupted cuts. Machining professionals install this insert into compatible toolholders for steel and cast iron turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for medium to semi-finish turning of steel as its primary workpiece material, with secondary suitability for cast iron. The PM chip breaker geometry is engineered to control chip formation across a range of depths of cut and feed rates typical in production turning environments. The T-Max P series is a common platform in industrial turning setups where consistent insert indexing and repeatability are required. CNC machinists and tool-and-die tradespeople are the primary installers of this insert type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD-coated with Al2O3, TiN, and TiCN for extended tool life in steel and cast iron machining\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape (TNMG) with six cutting edges for cost-efficient indexing\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry for controlled chip evacuation in medium turning applications\u003c\/li\u003e\n\u003cli\u003e0.5 inches inscribed circle diameter with a 0.0313 inches (1\/32 inches) corner radius\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for use in both left- and right-hand toolholder configurations\u003c\/li\u003e\n\u003cli\u003eRelief angle of 0 degrees (clearance code N) with tolerance code M for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for TNMG-style toolholders in the T-Max P series.

Use the appropriate torque wrench and manufacturer-specified clamping hardware when securing the insert via clamp or screw method. Inspect the insert seat and toolholder pocket for chips or debris before seating a new insert. Do not exceed the recommended depth of cut or feed rate parameters established in your toolholder and machine documentation.\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\u003eISO Code\u003c\/strong\u003e: TNMG 22 04 08-PM 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3, TiN, TiCN\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.52 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: 7861230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51729861804338,"sku":"7861230","price":40.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/204843ac804f13c04178ce9e794403eb.jpg?v=1788709608","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861230-turning-insert-tnmg432-pm-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
