It carries a multilayer PVD TiAlN and TiN coating and features the MR4 chip breaker geometry with a T-Land cutting edge style. The insert has an inscribed circle of 0.5000 inches, a corner radius of 0.2500 inches, and a maximum depth of cut of 0.2500 inches. With 8 usable cutting edges and a neutral hand orientation, it delivers consistent performance across facing, profiling, and turning operations. Licensed machinists and toolroom technicians are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated primarily for superalloys and titanium workpiece materials, making it well suited for aerospace, power generation, and high-temperature alloy machining applications. Secondary workpiece materials include steel, stainless steel, and cast iron. The MR4 chip breaker geometry supports reliable chip control across these material groups. It is appropriate for use in both roughing and finishing passes where T-Land edge preparation provides edge stability under interrupted or continuous cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound insert shape (RNMG) with 360-degree included angle and 8 cutting edges for maximum tool utilization\u003c\/li\u003e\n  \u003cli\u003eMultilayer PVD TiAlN and TiN coating in manufacturer grade TS2500 for heat and wear resistance in superalloy cutting\u003c\/li\u003e\n  \u003cli\u003eMR4 chip breaker with T-Land cutting edge style for controlled chip formation and edge stability\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry with 0-degree relief angle; insert style code N, tolerance code M\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock holding methods for toolholder flexibility\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: facing, profiling, and turning in a single insert grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in RNMG-style toolholders that accept a 0.5000-inch inscribed circle round insert with a 0.2028-inch hole diameter.

Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the appropriate torque wrench or insert screw driver specified by the toolholder manufacturer when securing clamp, pin, or lever lock components — do not overtighten by hand. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RNMG-MR4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TS2500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MR4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and TiN (Multilayer PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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 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: Superalloys and Titanium (Code: S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron (Codes: P, M, K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: S10, S20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Facing, Profiling, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: RNMG120400-MR4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: RNMG43-MR4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 02615967\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557987680562,"sku":"02615967","price":268.17,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/seco-02615967-turning-insert-rnmg-43-mr4-ts2500-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
