It carries a TM2501 manufacturer grade and uses a CVD-applied Duratomic coating of TiCN, Al2O3, and Cr for wear resistance and thermal stability. The trigon insert shape features an 80-degree included angle, a 0-degree relief angle (clearance code N), and an MF4 chip breaker geometry. The cutting edge is chamfered and honed with a negative rake angle of 30 degrees. With 6 cutting edges per insert, it delivers extended tool life per piece on demanding metal-removal operations.\u003c\/p\u003e\u003cp\u003eThis insert is designed for boring, facing, and turning applications. Its primary workpiece material is stainless steel (ISO material code M), with steel (code P) as a secondary application material. Material grades M25, M30, and M35 are supported. The neutral hand and WNMG series geometry make it appropriate for a range of medium to semi-finish cuts in production turning environments. It is suited for use in CNC lathes and turning centers where clamp, pin, or lever-lock insert holding is employed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD Duratomic TiCN plus Al2O3 plus Cr coating for heat and wear resistance on stainless steel and steel\u003c\/li\u003e\n\u003cli\u003eMF4 chip breaker geometry optimized for medium to semi-finish turning on difficult materials\u003c\/li\u003e\n\u003cli\u003e6 usable cutting edges per insert for lower cost per edge\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style for edge stability and reduced built-up edge\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever-lock toolholders in the WNMG series\u003c\/li\u003e\n\u003cli\u003eMulti-use capability across boring, facing, and turning operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in WNMG-series toolholders that accept clamp, pin, or lever-lock holding methods.

Seat the insert fully against the pocket locating surfaces before tightening the clamping mechanism to the toolholder manufacturer's specified procedure. Inspect the insert pocket for wear, chips, or debris before seating a new edge or indexing to the next cutting edge. Proper insert seating directly affects surface finish, tool life, and dimensional accuracy.\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\u003eIndustry Standard Number\u003c\/strong\u003e: WNMG331-MF4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG060404-MF4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TM2501\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: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (80-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative, 30 degrees\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\u003eInsert Length\u003c\/strong\u003e: 0.5134 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (1\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2508 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (Code M)\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\u003eMaterial Grade\u003c\/strong\u003e: M25, M30, M35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03276699\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560783446322,"sku":"03276699","price":31.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2f3212a9244016cd38ee28d9ebf1277_e8533eeb-7521-4b41-a615-887d2de7fa55.jpg?v=1786457342","url":"https:\/\/voomisupply.com\/products\/seco-03276699-wnmg331-mf4-tm2501-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
