It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN over a solid carbide substrate, grade 4415, providing wear resistance and thermal stability during continuous and semi-interrupted cuts. The insert has an 80-degree diamond shape with a neutral hand orientation, a 0.75-inch inscribed circle, and a 1.19 mm corner radius. It is intended for use by machinists and turning specialists working in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for turning steel (ISO P workpiece material code) and secondarily for cast iron (ISO K workpiece material code). The T-Max P series is suited for medium to finishing turning passes where consistent surface finish and predictable tool life are required. The PM chip breaker geometry supports chip control across a range of depths of cut and feed rates common in steel turning. Each package contains one insert; the minimum order quantity is 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear and crater resistance\u003c\/li\u003e\n\u003cli\u003eGrade 4415 solid carbide substrate optimized for steel and cast iron turning\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Shape Code C) with neutral hand\u003c\/li\u003e\n\u003cli\u003e4 usable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n\u003cli\u003ePM chip breaker for reliable chip control in medium turning applications\u003c\/li\u003e\n\u003cli\u003eISO code CNMG 19 06 12-PM 4415 for cross-reference ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG-style turning toolholders that accept a 0.75-inch (19.05 mm) inscribed circle insert with a 0.312-inch hole diameter and clamp or screw holding method.

Ensure the machine spindle is stopped and the turret is locked before indexing or replacing inserts. Seat the insert fully against the pocket locating surfaces and torque the clamp or screw per the toolholder manufacturer's specification. Inspect the insert pocket for chips or debris before seating a new edge to prevent premature fracture or dimensional error.\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\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, Shape Code C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\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\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.19 mm (0.0469 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.312 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N, Tolerance Code M)\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\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 19 06 12-PM 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.08 inches (L) x 2.13 inches (W) x 0.53 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 7859229\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51750511411506,"sku":"7859229","price":602.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68eaf8b9a0fd5b3eca0143e7e97e83de_b6d73cc3-7178-4450-8ebc-4666682709f9.jpg?v=1788916013","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859229-cnmg643-pm-4415-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
