It carries the ANSI and ISO designation PNCU0805GNR JIN70N and uses a silicon nitride (Si3N4) ceramic substrate in an uncoated finish. The insert features a pentagon shape with a negative rake angle, a GNR chip breaker, and 10 cutting edges, making it a productive choice for indexable milling operations where tool life and thermal resistance matter. The inscribed circle measures 0.4500 inches and thickness is 0.1900 inches. Installation is by screw-hold clamping, which is standard for this insert style.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling cast iron in industrial and production machining environments. The silicon nitride ceramic grade IN70N is engineered to withstand the elevated cutting temperatures associated with dry or semi-dry cast iron milling. Typical applications include face milling and shoulder milling on gray cast iron and nodular cast iron components. Compatible cutter series include 4W2A and DM5G, as specified by the manufacturer. Right-hand cutting orientation applies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon nitride (Si3N4) ceramic substrate, uncoated, optimized for cast iron milling\u003c\/li\u003e\n  \u003cli\u003ePentagon insert shape with 108-degree included angle and 10 usable cutting edges\u003c\/li\u003e\n  \u003cli\u003eGNR chip breaker geometry with corner-rounded cutting edge style\u003c\/li\u003e\n  \u003cli\u003eNegative rake, right-hand orientation with 0.0310-inch (1\/32 inch) corner radius\u003c\/li\u003e\n  \u003cli\u003eDouble-sided insert for extended indexing value per insert\u003c\/li\u003e\n  \u003cli\u003eScrew-clamping hold method compatible with 4W2A and DM5G cutter series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConfirmed compatible cutter series: 4W2A and DM5G.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key driver as specified by the cutter body manufacturer for the screw-clamp seat. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert, and ensure the pocket is clean and free of chips to achieve proper seating and insert stability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: PNCU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Pentagon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Silicon Nitride (Si3N4) Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IN70N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: PNCU0805GNR J IN70N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: PNCU0805GNR JIN70N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 0805\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.4500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Range\u003c\/strong\u003e: 0.4000 to 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.4500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Range\u003c\/strong\u003e: 0.4500 to 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.4500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1900 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Range\u003c\/strong\u003e: 0.1850 to 0.2000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0310 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 108 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0.00 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GNR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Cutter Series\u003c\/strong\u003e: 4W2A, DM5G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5811959\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52042865934642,"sku":"5811959","price":75.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c96802049b308cc25f6bdb4dd7e6484.jpg?v=1790028689","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-5811959-milling-insert-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
