This neutral-hand insert features a triangular shape with a 60-degree included angle, an inscribed circle of 0.75 inches (19.05 mm), and a corner radius of 0.0938 inches (3\/32 inch, 2.38 mm). The KCU10B grade substrate is coated with AlTiN (aluminum titanium nitride) for improved heat resistance and wear life at elevated cutting speeds. Six cutting edges per insert help reduce per-edge tooling cost in production environments. Machinists and toolroom operators use this insert in standard TNMG toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations on steel, stainless steel, and similar workpiece materials in both roughing and finishing passes where the RP chip breaker geometry is appropriate. The AlTiN coating supports dry or semi-dry cutting conditions at higher surface speeds. With an insert thickness of 0.375 inches (9.53 mm) and an inscribed circle of 0.75 inches, this is a larger-format insert appropriate for medium to heavy material removal applications on industrial turning centers and engine lathes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTNMG insert style with triangular shape and 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eKCU10B carbide grade with AlTiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eSix usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eRP chip breaker geometry for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard TNMG toolholders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0938 inches (3\/32 inch) for general turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for standard TNMG toolholders accepting a 0.75-inch inscribed circle triangular carbide insert with a 3\/8-inch insert thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Ensure the lathe or turning center is powered down and the spindle is fully stopped before indexing or replacing inserts. Use the correct torque wrench and insert-clamping hardware specified by the toolholder manufacturer — do not overtighten or undertighten the clamping screw. Inspect the toolholder pocket and shim seat for wear 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: TNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0938 inches (3\/32 inch, 2.38 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.375 inches (9.53 mm)\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\u003eChip Breaker\u003c\/strong\u003e: RP\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\u003eInsert Size Code\u003c\/strong\u003e: 666\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7090631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730122670386,"sku":"7090631","price":461.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/417bf587a42a1a2db1a6fdb6901dfe31.jpg?v=1788712099","url":"https:\/\/voomisupply.com\/products\/kennametal-7090631-tnmg-carbide-turning-insert-0-75-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
