It carries the manufacturer grade 4335 with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, providing wear resistance and thermal protection under continuous and interrupted cutting conditions. The insert features an 80-degree diamond shape, a neutral hand orientation, a 1\/2-inch inscribed circle (0.5000 inches), and a 1\/32-inch corner radius (0.0313 inches). It is suited for production turning operations where consistent tool life and surface finish on steel are priorities.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in CNC turning centers and manual lathes equipped with compatible CNMG toolholders. It is primarily applied to steel turning applications and is appropriate for both roughing and finishing passes depending on depth of cut and feed rate selection. The PM chip breaker geometry is optimized for medium-duty steel turning. Installation and tool management are typically handled by machinists, CNC operators, and toolroom technicians in metalworking and manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended wear life on steel\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG style) with neutral hand for versatile turning orientations\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry suited for medium-duty steel turning applications\u003c\/li\u003e\n\u003cli\u003e4 usable cutting edges per insert, reducing per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eISO designation CNMG 12 04 08-PM 4335 for cross-reference with international toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG-style toolholders compatible with the T-Max P series.

Use the appropriate torque wrench and manufacturer-recommended seating procedure to secure the clamp without cracking the insert. Inspect the insert pocket and shim for wear or debris before seating a new insert. Insert indexing and toolholder setup should be performed by qualified machinists or CNC toolroom personnel following applicable shop safety procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4335\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 degrees)\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: PM\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: 1\/2 inch (0.5000 inches \/ 12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches \/ 0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches \/ 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches (5.16 mm)\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\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 12 04 08-PM 4335\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7080821\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737104220466,"sku":"7080821","price":250.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4da318b99ec3f782aaa10663c19d362c_5bfb9f29-32f9-44bf-9049-e5dcf44b1463.jpg?v=1788784282","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7080821-cnmg432-pm-4335-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
