It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which builds heat and wear resistance for sustained cutting performance. The insert features a 55-degree diamond shape, a 0 degree relief angle (clearance code N), and a tolerance code M for consistent seating. With an inscribed circle of 0.5 inches and a corner radius of 0.031 inches, it fits standard DNMG toolholders and is suited for medium to semi-finish turning operations. Licensed machinists and CNC operators install and index these inserts as part of production turning setups.\u003c\/p\u003e\u003cp\u003eThis insert is designed for turning and boring applications on cast iron and steel workpieces, corresponding to ISO material groups K and P. The GN chip breaker geometry is optimized for controlled chip formation in these materials. Maximum depth of cut is 4.00 mm (0.157 inches), making it well suited for medium-duty material removal passes in both manual and CNC turning environments, including internal boring applications where the multi-use designation applies. It conforms to ISO 13399 standards and carries the ISO code DNMG 432-GN.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with IC8150 grade for strength and thermal stability\u003c\/li\u003e\n\u003cli\u003eCVD multilayer coating: TiCN base, Al2O3 mid-layer, TiN top coat for extended tool life on ferrous materials\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with 0-degree relief angle for rigid, stable clamping\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.031 inches (1\/32 inch) for semi-finish surface quality\u003c\/li\u003e\n\u003cli\u003eCompatible with both clamp and pin insert holding methods\u003c\/li\u003e\n\u003cli\u003eMulti-use designation supports both external turning and boring operations\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-compatible replacement or direct-fit indexable insert for DNMG-style toolholders accepting a 55-degree diamond insert with a 1\/2 inch inscribed circle, tolerance code M, and clearance code N.

Ensure the machine spindle is fully stopped and the toolholder is secure before seating or indexing the insert. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not over-torque the clamping screw. Inspect the insert seat and chip pocket for debris before installation to ensure full contact and accurate seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 432-GN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC8150\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: 0.031 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.49 mm (0.610 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.187 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.00 mm (0.157 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\u003eChip Breaker\u003c\/strong\u003e: GN\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: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5508220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51733617279282,"sku":"5508220","price":324.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc9d02eed238543360d23655542d6700.jpg?v=1788756969","url":"https:\/\/voomisupply.com\/products\/iscar-5508220-dnmg432gn-ic8150-turning-insert-55-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
