It features an 80-degree diamond (rhombic) insert shape, a 1\/2-inch inscribed circle, and a 1\/64-inch (0.0157 inch) corner radius. The WSM10 grade is paired with a multilayer PVD coating  -  TiAlN, Al2O3, and ZrCN  -  engineered for cutting stainless steel, superalloys, and titanium as primary workpiece materials. With four usable cutting edges and an NF4 chip breaker geometry, this insert suits production turning operations where edge security and chip control on difficult materials are priorities. Licensed machinists and CNC operators install this insert in compatible toolholders for turning, facing, and boring applications.\u003c\/p\u003e\u003cp\u003eThis insert targets finish-to-medium turning of stainless steel (ISO material group M), superalloys, and titanium (ISO material group S) as its primary application, with steel (ISO material group P) as a secondary workpiece material. The NF4 chip breaker geometry and honed cutting edge style are optimized for these demanding materials in both roughing and finishing passes. Maximum depth of cut reaches 0.1692 inch, making it suitable for moderate stock removal as well as finishing work. Typical installation platforms include negative-rake CNMG-compatible toolholders used on CNC lathes and machining centers in job shop, aerospace, and medical manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond insert shape with four cutting edges for maximum indexing economy\u003c\/li\u003e\n\u003cli\u003eWSM10 grade with multilayer PVD coating (TiAlN, Al2O3, ZrCN) for wear resistance on stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eNF4 chip breaker geometry with honed cutting edge for controlled chip evacuation on tough materials\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation with clamp and pin holding method for secure seating in the toolholder\u003c\/li\u003e\n\u003cli\u003eCompatible with turning, facing, and boring operations on the same insert\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO dimensional standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to seat in negative-rake CNMG-style toolholders accepting a 1\/2-inch inscribed circle insert with clamp and pin holding.

Use the correct torque wrench and manufacturer-specified clamping hardware for the toolholder; do not over-tighten the clamp screw or lock pin. Inspect the insert seat and clamping surfaces for chips or debris before seating a new edge. Disposal of worn carbide inserts should follow applicable shop waste and recycling procedures for tungsten carbide.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120404\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: 1\/2 inch (0.5000 inch \/ 12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5080 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1692 inch\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 Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WSM10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M10, P10, S10\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: NF4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 18 degrees (Negative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02205 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: WALTER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5847591\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":52102690799922,"sku":"5847591","price":293.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a95d301e482485a1c19d5143f8d5628d.jpg?v=1790070656","url":"https:\/\/voomisupply.com\/products\/walter-5847591-turning-insert-cnmg431-nf4wsm10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
