This CNMG432EUP insert features the AC520U grade with a PVD-applied ZX proprietary coating, delivering a controlled balance of wear resistance and toughness suited to stainless steel and superalloy workpieces. The 80-degree diamond (rhombic) insert shape, neutral hand orientation, and EUP chip breaker geometry support stable chip control during roughing and medium machining passes. A 0.0313-inch corner radius and 0.5079-inch insert length define the cutting envelope. The insert uses a negative side clearance (N clearance code) with a positive rake angle of 10 degrees, optimizing cutting forces on difficult-to-machine materials.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use on CNC turning centers and conventional lathes processing stainless steel (ISO material group M) and special or super alloys (ISO material group S). The EUP chip breaker is specifically designed for roughing to medium machining operations where consistent chip evacuation and edge stability are critical. Typical applications include shaft turning, facing, and profiling on aerospace, medical, and industrial components made from austenitic stainless steels and nickel-based superalloys. The insert seats in CNMG-style toolholders using clamp or pin holding methods.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAC520U grade with PVD ZX coating for wear resistance on stainless steel and superalloys\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG) with neutral hand for versatile tool path options\u003c\/li\u003e\n\u003cli\u003eEUP chip breaker geometry optimized for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003ePositive 10-degree rake angle reduces cutting forces on work-hardening materials\u003c\/li\u003e\n\u003cli\u003eNegative side clearance with M tolerance for consistent seating and repeatability\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards; ISO code CNMG120408N-UP\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG432-style toolholders accepting clamp or pin insert holding.

Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer  -  do not overtighten clamp screws as this can fracture the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before seating the insert. Follow the toolholder manufacturer's recommended clamping torque and verify tool runout before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code (Full)\u003c\/strong\u003e: CNMG120408N-UP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC520U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary Coating Designation\u003c\/strong\u003e: ZX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EUP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing and Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\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 Code\u003c\/strong\u003e: M (Stainless Steel) and S (Superalloy)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2 and C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI and ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.5 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: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19HW360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51743248515378,"sku":"19HW360","price":172.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab16ea2107c2d422326120bf9f0ec491.jpg?v=1788844492","url":"https:\/\/voomisupply.com\/products\/sumitomo-19hw360-turning-insert-cnmg432eup-ac520u-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
