It carries a multi-layer CVD coating of TiCN, Al2O3, and TiN, engineered to handle the heat and abrasion generated during steel turning operations. The triangular insert shape (code T) with an 11-degree relief angle and a 0.0313-inch corner radius makes it well suited for profiling and finishing passes where controlled chip geometry and edge stability matter. This insert is installed by machinists and CNC lathe operators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed primarily for steel workpieces (primary material: Steel) and is also rated for use with secondary workpiece material category K. It is used in external turning applications on CNC lathes and turning centers where a clamp-held, neutral-hand insert is required. The TPMR geometry suits light to medium-depth finishing and semi-finishing cuts where close tolerances and surface finish quality are priorities. Clearance code P and tolerance code M define the seating and dimensional precision class of this insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMulti-layer CVD coating: TiCN, Al2O3, and TiN for thermal resistance and wear life on steel\u003c\/li\u003e\n  \u003cli\u003e0.0313-inch corner radius for controlled edge geometry on finishing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003e0.5-inch inscribed circle (IC) with triangular insert shape code T\u003c\/li\u003e\n  \u003cli\u003e11-degree relief angle (clearance code P) for positive-clearance cutting action\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard TPMR-style toolholders using clamp-style holding\u003c\/li\u003e\n  \u003cli\u003eChip breaker designation 53 for chip control in steel turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-replacement turning insert for TPMR-series toolholders that accept a triangular solid carbide insert with a 0.5-inch inscribed circle, tolerance code M, and clamp-style holding.

Use the correct torque driver for the clamping screw to avoid cracking the carbide body — do not overtighten by hand. Inspect the toolholder pocket and clamping components for debris or wear before seating a new insert. Follow the machine manufacturer and insert supplier guidelines for feed rate and depth-of-cut parameters appropriate to the grade and coating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPMR 22 04 08 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: TPMR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangular (Code T)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: 53\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.08 inches L x 2.13 inches W x 0.54 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23171618\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: 8019558\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731698221362,"sku":"8019558","price":373.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a610c2dfc15af2a28375b3a72846f88.jpg?v=1788733996","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-8019558-turning-insert-tpmr-22-04-08-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
