It belongs to the Isoturn series and is designed for single-point turning operations on CNC lathes and turning centers. The insert features an 80-degree trigon (W) shape with a neutral (N) clearance angle and M tolerance class. The M3M chip breaker geometry supports stable chip control across a range of feed rates. With a submicron carbide grade and IC806 manufacturer grade, this insert is built for demanding cutting conditions, particularly in high-temperature alloy applications. Licensed machinists and CNC operators in production and job-shop environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for turning superalloys and titanium alloys, material codes classified as S-grade workpiece materials. These materials are common in aerospace, medical, and energy-sector component machining where tool life and edge integrity under heat and pressure are critical. The double-ended design provides two usable cutting edges per insert, extending value in high-volume production runs. It is held in the toolholder via clamp and pin mounting methods, compatible with standard WNMG-style toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating with SumoTec proprietary process for heat resistance and extended tool life in difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eM3M chip breaker optimized for controlled chip formation on superalloys and titanium\u003c\/li\u003e\n\u003cli\u003eDouble-ended insert delivers two cutting edges per piece\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide substrate grade IC806 for toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry reduces cutting forces on heat-sensitive workpiece materials\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 standards for tooling data representation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use insert for WNMG 331-style toolholders that accept clamp-and-pin insert holding.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or replacing inserts. Use the appropriate torque wrench per the toolholder manufacturer's specifications when securing the clamping screw — do not over-torque. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper seating and edge alignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG 331-M3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (80 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC806\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide (Submicron)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (SumoTec, PVD process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 6.53 mm (0.257 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.51 mm (0.138 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\u003eRake\u003c\/strong\u003e: Positive\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\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy, Titanium (Code: S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5566737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51734679683378,"sku":"5566737","price":189.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39230f0d7a15d15ca2548c2bb0c652d9.jpg?v=1788764773","url":"https:\/\/voomisupply.com\/products\/iscar-5566737-wnmg-331-m3m-ic806-turning-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
