This triangular insert features a CVD-applied multilayer coating of Al2O3 and TiCN for wear resistance and thermal stability at the cutting edge. It carries a 60-degree included angle, a 0.0160-inch corner radius, and a 0.3790-inch insert length, making it suited for light-to-moderate depth-of-cut finishing and semi-finishing passes. The neutral hand orientation and positive rake geometry support consistent chip flow. Licensed machinists and CNC turning technicians are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use on steel workpieces, classified under ISO material group P. It fits standard TCMT-style toolholders using a screw-clamp holding method. The MT chip breaker geometry is designed to manage chip control during moderate feed rates on low-to-medium carbon steels, alloy steels, and similar ferrous materials. Typical applications include OD turning, facing, and light profiling operations where consistent surface finish and dimensional accuracy are required. The three available cutting edges extend tooling economy per insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD-applied Al2O3 and TiCN multilayer coating for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eTT8125B manufacturer grade optimized for steel (ISO P) turning\u003c\/li\u003e\n\u003cli\u003e60-degree triangle shape with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eMT chip breaker geometry for controlled chip formation during steel turning\u003c\/li\u003e\n\u003cli\u003eThree cutting edges per insert for extended tooling value\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method for secure, repeatable seating in TCMT toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for TCMT-style screw-clamp turning toolholders accepting a 731 insert size, ISO code TCMT090204MT TT8125B, within the TCMT series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed by a qualified machinist or CNC tooling technician. Before indexing or replacing inserts, power down and lock out the machine spindle per facility lockout\/tagout procedures. Use the appropriate Torx or hex key at the manufacturer-specified torque range for TCMT screw-clamp seats  -  consult the toolholder documentation for seating torque, as no torque value is provided in this product data. Inspect the insert pocket and clamp screw for debris or damage before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT090204MT TT8125B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 731\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TT8125B\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 (60 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: MT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Al2O3, TiCN, Titanium Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3790 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2190 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0940 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0790 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 Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\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\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6212640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51971388244274,"sku":"6212640","price":23.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85e987feef71002d7123d92f3a3617e4.jpg?v=1789956564","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-6212640-turning-insert-tcmt731mt","provider":"Voomi Supply","version":"1.0","type":"link"}
