It carries the manufacturer grade 4335 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted cuts. The insert has a 3\/4 inch inscribed circle (IC), a 1\/4 inch thickness, and a 3\/64 inch corner radius (0.0469 inches). With four cutting edges and a neutral hand orientation, it delivers consistent tool life in production turning environments. Licensed machinists and CNC lathe operators are the primary installers of this insert type.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external and internal turning of steel components in both light finishing and medium roughing passes. The PR chip breaker geometry is optimized for steel cutting, promoting reliable chip control across a range of feed rates. It fits into CNMG-compatible toolholders with clamp and pin holding methods. Typical applications include shaft turning, facing, and profiling on CNC lathes in job shop and production floor environments. The ISO code for this insert is CNMG 19 06 12-PR 4335.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended wear resistance on steel\u003c\/li\u003e\n\u003cli\u003ePR chip breaker geometry optimized for steel turning applications\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG) with neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for reduced tooling cost per edge\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003ePart of the SANDVIK COROMANT T-Max P series for steel turning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG-style indexable toolholders that accept clamp and pin insert retention with a clearance code of N and tolerance code of M.

Power down and lock out the machine spindle before changing or indexing inserts. Inspect the toolholder pocket for debris or damage before seating a new insert. Do not force the insert into the pocket; improper seating can cause insert fracture or workpiece damage.\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\u003eISO Code\u003c\/strong\u003e: CNMG 19 06 12-PR 4335\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 80-Degree Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4335\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 Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inches \/ 19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 inches \/ 1.19 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches \/ 6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3120 inches (7.93 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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PR\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: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 7080866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731292062002,"sku":"7080866","price":541.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d386ff38f3537a84c6288e988a2a90d.jpg?v=1788729338","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7080866-turning-insert-cnmg643-pr-4335","provider":"Voomi Supply","version":"1.0","type":"link"}
