Manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, this insert is engineered for productive cutting in steel workpiece materials. It features a 5\/8 inch (0.625 inch) inscribed circle, a 1\/32 inch (0.0313 inch) corner radius, and an 80-degree diamond shape (C-shape), providing a strong cutting edge geometry suited for medium to finish turning passes. The PR chip breaker geometry promotes controlled chip flow during steel turning at varying depths and feed rates.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in steel turning applications in both production and job-shop environments. The T-Max P series positions it for general-purpose steel turning, including low-alloy and medium-carbon steels, where consistent tool life and surface finish are priorities. The neutral hand orientation makes it compatible with both right-hand and left-hand toolholders. With four usable cutting edges per insert, it delivers practical economy in high-cycle turning programs on manual or CNC turning equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance in steel cutting\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (CNMG) insert shape with 4 cutting edges per insert\u003c\/li\u003e\n\u003cli\u003ePR chip breaker geometry optimized for steel turning applications\u003c\/li\u003e\n\u003cli\u003e5\/8 inch inscribed circle with 1\/4 inch insert thickness for rigid clamping\u003c\/li\u003e\n\u003cli\u003e1\/32 inch corner radius for medium to finish turning passes\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit indexable insert for CNMG 16 06 08 toolholder seats (ISO code CNMG 16 06 08-PR 4335).

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and seating screw specified by the toolholder manufacturer when securing the insert clamp — do not over-tighten by hand. Inspect the toolholder seat and chip pocket for debris or damage before seating a new insert edge.\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\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\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, C-shape)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inch \/ 15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inch \/ 0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inch (6.35 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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 16 06 08-PR 4335\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 7080861\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748686758194,"sku":"7080861","price":392.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d386ff38f3537a84c6288e988a2a90d_75c85d81-bf1d-4735-bbbf-23087f3511f3.jpg?v=1788896726","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7080861-turning-insert-cnmg542-pr-4335","provider":"Voomi Supply","version":"1.0","type":"link"}
