Built from carbide substrate and coated via CVD with a TiCN, Al2O3, and TiN multilayer system, this insert delivers wear resistance and thermal protection during aggressive cuts. It carries an 8 cutting edges on a square insert body with a 90-degree included angle and a 3\/64 inch corner radius. The MR chip breaker geometry is engineered to manage chip control in medium-roughing to finishing passes. This insert is installed by CNC machinists and toolroom technicians working on production turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily suited for turning stainless steel workpieces, corresponding to ISO workpiece material code M. It belongs to SANDVIK COROMANT's T-Max P series, which targets external and internal turning operations where consistent chip breaking and edge life are critical. The neutral hand orientation makes it compatible with standard right-hand and left-hand toolholders configured for SNMG insert pockets. Typical applications include shaft turning, facing, and contour passes on stainless and similar difficult-to-machine alloys in both job-shop and production environments. ISO designation for this insert is SNMG 19 06 12-MR 2025.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-applied TiCN, Al2O3, and TiN multilayer coating for thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e8 usable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003eMR chip breaker geometry optimized for stainless steel medium-roughing operations\u003c\/li\u003e\n  \u003cli\u003e3\/64 inch corner radius provides a balance of edge strength and surface finish capability\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard SNMG-style toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method for secure seating under interrupted and continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders with SNMG insert pockets (insert style SNMG, clearance code N, tolerance code M).

Always power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key torque wrench as specified by the toolholder manufacturer for the clamping screw — do not over-tighten or under-tighten the clamp. Inspect the insert pocket seat and clamp pin for wear or debris before seating a new insert edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMG 19 06 12-MR 2025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (90-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.7028 inches (3\/4 inch nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3120 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 and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.65 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5750391\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51734853255474,"sku":"5750391","price":647.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05531d5e07e18e949bd2101e0e9b8792_8989bc96-11fa-4ebd-930a-0c2bb823bf1d.jpg?v=1788767355","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5750391-turning-insert-snmg643-mr-2025","provider":"Voomi Supply","version":"1.0","type":"link"}
