It features an 80-degree trigon (W) insert shape with a neutral hand orientation and a positive rake angle of 16 degrees. The inscribed circle measures 0.5 inches, the corner radius is 0.0156 inches (1\/64 inch), and the insert thickness is 0.1875 inches (3\/16 inch). Designed for precision turning operations, this insert is held in place via clamp and pin and is manufactured uncoated for direct application. Machining professionals in aerospace and industrial shops will recognize the EH520 solid carbide grade as a purpose-built solution for superalloy materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed primarily for turning superalloy workpiece materials, making it a common selection in aerospace and energy sector machining environments. The EEX chip breaker geometry and positive rake promote clean chip evacuation and reduced cutting forces during tight-tolerance turning passes. It is packaged individually and suited for CNC turning centers where WNMG-style toolholders are employed. The ISO equivalent code is WNMG080404N-EX, and the insert meets ANSI and ISO 13399 standards, making it compatible with toolholder systems documented to those specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, EH520 manufacturer grade — optimized for superalloy turning\u003c\/li\u003e\n  \u003cli\u003eWNMG431EEX ANSI code with ISO equivalent WNMG080404N-EX for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eEEX chip breaker geometry with 16-degree positive rake angle for efficient chip control\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no coating process applied, suitable where coating-induced edge prep is undesirable\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert for use in both left- and right-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure seating under high-load superalloy cutting conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in WNMG-style toolholders meeting ANSI and ISO 13399 standards.

Seat the insert fully against the toolholder pocket before engaging the clamp and pin mechanism — partial seating can cause insert fracture under cutting loads. Inspect the pocket and locating pin for wear or debris before each insert change. Superalloy turning typically demands conservative feed and speed parameters; consult the toolholder manufacturer and cutting data documentation for starting recommendations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: WNMG431EEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG080404N-EX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (W) — 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: EH520\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\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\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3425 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 16 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003eChip Breaker\u003c\/strong\u003e: EEX\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\u003c\/strong\u003e: Superalloy (Code S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 inches L x 1.5 inches W x 0.44 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.026 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 19EA177\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51754311811378,"sku":"19EA177","price":22.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df8d20d48f0e95bf56489c22c33d3308.jpg?v=1788944364","url":"https:\/\/voomisupply.com\/products\/sumitomo-19ea177-wnmg431eex-eh520-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
