The insert features an 80-degree diamond shape (ANSI code CNMM432EHG, ISO code CNMM120408N-HG) with a neutral rake angle and a 0-degree relief angle (clearance code N, tolerance code M). It measures 0.5079 inches in length with a 0.5000-inch inscribed circle and a 0.0313-inch (1\/32-inch) corner radius. Insert thickness is 0.1875 inches (3\/16 inch). The EHG chip breaker geometry is suited to controlled-chip applications in turning operations. Licensed machinists and CNC turning-center operators are the primary installers of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning operations on steel workpieces (secondary workpiece material code P), making it appropriate for general-purpose external and internal turning on CNC lathes and manual turning centers. The CNMM insert style is held by clamp and pin method, which is standard on a wide range of tool holders designed for the CN series. The AC820P grade with CVD Al2O3 coating provides wear resistance suited to continuous and light-interrupted cuts on steel. This insert is sold individually but carries a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with CVD-applied Al2O3 coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eAC820P manufacturer grade optimized for steel turning applications\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (shape code C) for versatile approach angles\u003c\/li\u003e\n  \u003cli\u003eEHG chip breaker geometry for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eNeutral rake and 0-degree relief angle (clearance code N) for stable cutting edge\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method compatible with standard CN-series tool holders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CN-series tool holders that accept CNMM-style inserts held by clamp and pin method.

Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and seating surface for chips or debris before seating a new insert, as contamination can cause improper seating and premature edge failure. Verify clamp and pin engagement before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMM432EHG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMM120408N-HG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMM\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\u003eManufacturer Grade\u003c\/strong\u003e: AC820P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Al2O3\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: EHG\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: 0.0313 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (clearance code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (neutral)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 19RJ495\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51740659777842,"sku":"19RJ495","price":188.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87d279b8502e6a8c253235de0bc35ced.jpg?v=1788826541","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rj495-turning-insert-cnmm432ehg-ac820p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
