It carries an 80-degree diamond (rhombic) insert shape with a 5\/8-inch inscribed circle and a 1\/32-inch corner radius. The WSM20 grade features a multilayer PVD coating combining TiAlN, Al2O3, and ZrCN for heat resistance and wear performance in the M20, S20, and P20 material grade range. With four cutting edges and a negative rake geometry, this insert delivers consistent performance across roughing and medium machining operations. Licensed HVAC techs, machinists, and tooling specialists in metalworking and precision manufacturing are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on CNC lathes and turning centers handling stainless steel and superalloy workpieces, with secondary application in general steel machining. The NM4 chip breaker geometry is optimized for roughing and medium machining, managing chip flow effectively at moderate-to-heavy depths of cut. The insert seats in CNMG-compatible toolholders using clamp or pin holding methods. The neutral hand orientation allows use in a variety of standard toolholder setups commonly found in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG542 ANSI insert code (ISO: CNMG160608) for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eWSM20 carbide grade with multilayer PVD TiAlN, Al2O3, ZrCN coating for high-temp resistance\u003c\/li\u003e\n  \u003cli\u003eNM4 chip breaker designed for roughing and medium machining of stainless steel and superalloys\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges with honed cutting edge style for improved edge stability\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with negative rake and 0-degree relief angle (clearance code N)\u003c\/li\u003e\n  \u003cli\u003eSupports turning, facing, and boring in a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style toolholders accepting a 542 ANSI size code insert with clamp or pin holding.

Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before seating or replacing inserts. Use the correct clamping screw torque specified by the toolholder manufacturer for CNMG clamp-style or pin-style seats. Inspect the toolholder pocket and seating surfaces for debris or wear before installing a fresh insert edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG542\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG160608\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2113 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WSM20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M20, P20, S20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN, Al2O3, ZrCN (Multilayer PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: NM4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.051 pounds\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: 23242105\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: WALTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5584718\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":51996015984946,"sku":"5584718","price":457.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96ffa823a781e8286c9d4dceb02b5a46_e8cb4e9d-4c0e-4ec7-932f-8f3bc07e4993.jpg?v=1789993080","url":"https:\/\/voomisupply.com\/products\/walter-5584718-turning-insert-cnmg542-nm4wsm20-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
