Carrying the TS2500 manufacturer grade, this insert is engineered primarily for machining superalloys and titanium, with secondary suitability for steel, stainless steel, and cast iron. It features an 80-degree diamond insert shape, a negative rake geometry, and a T-Land cutting edge style paired with the MR4 chip breaker. With four usable cutting edges and a 0.5-inch inscribed circle, this insert is suited for high-productivity turning, facing, and boring operations on CNC lathes and turning centers. Licensed machinists and toolroom professionals select this grade for demanding aerospace and energy-sector workpieces.\u003c\/p\u003e\n\u003cp\u003eThe 02615956 fits standard CNMG-style toolholders and is applicable across a range of turning center setups in both job shop and production environments. Compatible holding methods include clamp, pin, and lever lock styles. The MR4 chip breaker geometry is optimized for moderate to heavy material removal on difficult-to-machine superalloys and titanium alloys. It also performs reliably in steel and stainless steel finishing and semi-finishing passes. This insert follows both ANSI and ISO standards, with an ISO designation of CNMG120408-MR4 and an industry standard number of CNMG432-MR4, making cross-referencing to toolholder catalogs straightforward.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with multilayer PVD TiAlN and TiN coating for extended tool life on superalloys and titanium\u003c\/li\u003e\n  \u003cli\u003eMR4 chip breaker with T-Land cutting edge style for controlled chip formation in difficult materials\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum indexing value\u003c\/li\u003e\n  \u003cli\u003eNegative rake, neutral hand geometry compatible with clamp, pin, and lever lock toolholders\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: boring, facing, and turning from a single insert style\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ISO code CNMG120408-MR4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style toolholders accepting a 432 insert size with clamp, pin, or lever lock holding methods.

Always power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket and tighten the clamping screw or lever to the toolholder manufacturer specifications. Inspect the insert pocket for chips or debris before seating a new cutting edge to ensure proper support and 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: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNMG-MR4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TS2500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: S10, S20\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: Diamond 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MR4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD Multilayer\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\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\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: 0.4764 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120408-MR4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG432-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  \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\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: 02615956\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560255684914,"sku":"02615956","price":314.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/516b8d677632fb50cc5817edcfac94e2.jpg?v=1786449719","url":"https:\/\/voomisupply.com\/products\/seco-02615956-cnmg-432-mr4-ts2500-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
