Coated with TiAlN and AlCrN via a PVD process under the proprietary Super ZX designation, this insert delivers thermal and wear resistance suited to demanding cutting conditions. The 80-degree diamond shape with a neutral hand orientation provides versatility across a range of turning operations. A 0.0156-inch corner radius and positive rake angle of 7 degrees help reduce cutting forces. Qualified CNMG machinists and CNC lathe operators install this insert as a direct drop-in for compatible toolholders.\u003c\/p\u003e\n\u003cp\u003eThe 19HM334 is engineered for turning applications where stainless steel is a primary or secondary workpiece material, making it well suited to job shops, aerospace component machining, and precision manufacturing environments. The EGU chip breaker geometry promotes controlled chip formation during light-to-medium roughing and finishing passes. It conforms to ANSI and ISO 13399 standards, with an ISO code of CNMG120404N-GU, ensuring broad toolholder compatibility across ISO-compliant setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN and AlCrN PVD coating (Super ZX designation) for enhanced thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with neutral hand for versatile turning setups\u003c\/li\u003e\n  \u003cli\u003eEGU chip breaker geometry for controlled chip formation in stainless steel and similar materials\u003c\/li\u003e\n  \u003cli\u003e0.0156-inch corner radius for balance between edge strength and surface finish\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 7 degrees reduces cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards; ISO code CNMG120404N-GU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement turning insert for CNMG-style toolholders accepting a 1\/2-inch inscribed circle insert with clamp or pin holding methods.

Power down and lock out the machine spindle before changing inserts. Inspect the toolholder pocket and seating surface for chips or debris before seating the insert, as foreign material will affect insert alignment and can cause premature edge failure. Follow the toolholder manufacturer torque specifications for the clamping screw; do not exceed the recommended clamp force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 degree included angle)\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: AC530U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and AlCrN (Super ZX PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EGU\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: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\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 (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 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\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\u003eInsert Material\u003c\/strong\u003e: Carbide\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\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120404N-GU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI and ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19HM334\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51731195298098,"sku":"19HM334","price":25.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/943eda00cc83a2c1e26ad5d5df26bba0.jpg?v=1788728160","url":"https:\/\/voomisupply.com\/products\/sumitomo-19hm334-turning-insert-cnmg431egu-ac530u-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
