It carries the ANSI designation CCMT433 and ISO designation CCMT 12 04 12-PM 4425, with an 80-degree diamond (rhombic) insert shape. The substrate is coated via CVD with a TiCN, Al2O3, and TiN multilayer stack, delivering high wear resistance with moderate toughness. The PM chip breaker geometry supports roughing and medium machining applications. Inscribed circle diameter is 0.5000 inches (12.70 mm) and corner radius is 1.19 mm (0.0469 inches). Installed by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for steel (ISO material group P) with secondary suitability for cast iron (ISO material group K). Grade 4425 sits in the high-to-moderate wear-resistance range, making it well suited for continuous and lightly interrupted cuts at moderate-to-high cutting speeds. The PM chip breaker handles chip control during roughing passes and medium material removal rates. The neutral hand orientation and positive side clearance (7-degree relief angle) allow flexible toolholder pairing. Typical applications include shaft turning, facing, and profiling on low-to-medium alloy steels and gray cast iron components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for extended tool life on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CCMT) provides two cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry optimized for roughing and medium machining passes\u003c\/li\u003e\n  \u003cli\u003e1.19 mm corner radius balances surface finish quality with edge strength\u003c\/li\u003e\n  \u003cli\u003ePositive side clearance (7-degree relief angle) reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eAccepts clamp or screw insert holding methods for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders that accept CCMT433 (ISO CCMT 12 04 12) inserts with a 5.50 mm hole diameter. Compatible toolholders use either clamp or screw clamping methods. Verify toolholder bore and seating geometry before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine spindle stopped and all axis motion locked out per the machine tool builder lockout procedure. Use the correct Torx or hex key to the toolholder manufacturer specified torque when securing a screw-lock style pocket; do not overtighten, as carbide inserts are brittle and will crack under excessive clamping load. Inspect the insert seat and clamping surfaces for chips or debris before seating the insert. Handle carbide inserts with care to avoid chipping cutting edges prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT433\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT 12 04 12-PM 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80-Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Layers\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM (Roughing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 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: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches (5.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp or Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.43 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7860815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51730453201202,"sku":"7860815","price":331.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61f0724fbbc708d7aef204a7487267de_afef82eb-6169-4d7e-9d88-c9782ff08e52.jpg?v=1788717702","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860815-turning-insert-ccmt433-pm-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
