The insert features a multilayer MTCVD TiCN and Al2O3 coating applied over a solid carbide substrate, delivering thermal resistance and wear protection across demanding applications. It carries a negative rake angle of 15 degrees, a honed cutting edge, and an FP chip breaker geometry. With 4 usable cutting edges and compatibility with both clamp and pin holding methods, this insert is suited for production turning environments where consistent tool life and predictable performance are required.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium. It fits the KENLOC toolholding system and is appropriate for use in both roughing and semi-finishing passes where moderate depth of cut and controlled chip formation are priorities. The maximum depth of cut is 1.25 mm (0.0492 inches), making it well suited for medium-material-removal scenarios. Licensed machinists, CNC operators, and tool crib technicians working in job shop or production environments will recognize this as a standard CNMG format insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCM15 grade with multilayer CVD coating: TiCN plus Al2O3 for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eFP chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert with neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method for secure seating in KENLOC toolholders\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge for consistent entry and reduced built-up edge\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO industry standards for CNMG insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification replacement and production insert for KENLOC-series toolholders accepting CNMG-style inserts with a 0.5-inch inscribed circle.

Ensure the toolholder pocket and clamp surfaces are clean and free of chips before seating the insert. Use the appropriate torx or clamp screw torque as specified by the toolholder manufacturer  -  do not use the insert manufacturer torque values from memory, as they vary by holder. Verify insert seating and edge orientation before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG431FP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD (CVD Classification)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.5077 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches (5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative, 15 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 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\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\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI and ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3758783\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742240899378,"sku":"3758783","price":183.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9905fd6ab077cbb22e924a01388b9df4.jpg?v=1788836129","url":"https:\/\/voomisupply.com\/products\/kennametal-3758783-cnmg431fp-kcm15-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
