The diamond-shaped (80-degree included angle) insert carries a negative rake geometry and a chamfered and honed cutting edge. It measures 12.9 mm (0.5077 inches) in length with a 0.5-inch inscribed circle and a 1\/32-inch (0.0313-inch) corner radius. With four available cutting edges and a 3\/16-inch thickness, it delivers efficient material removal in both roughing and finishing passes. Licensed machinists, CNC operators, and tool-and-die professionals install this insert as part of the KENLOC series tooling system.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for turning, facing, and boring operations on steel and cast iron workpieces, corresponding to ISO material codes P and K. It is suited for both general-purpose production turning and applications requiring consistent surface finish across multiple cutting edges. The MN chip breaker geometry is designed to manage chip flow during medium-duty cuts on ferrous materials. A maximum depth of cut of 0.1691 inches supports a range of material removal strategies common in job shop and production floor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCP25C grade with multilayer CVD coating: TiN outer layer, Al2O3 mid-layer, TiCN base layer for wear and thermal resistance\u003c\/li\u003e\n  \u003cli\u003eDiamond insert shape with 80-degree included angle for versatile toolpath options\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges for extended tool life per insert\u003c\/li\u003e\n  \u003cli\u003eMN chip breaker geometry optimized for steel and cast iron at medium depths of cut\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods for secure seating in KENLOC toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO designation CNMG120408MN\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC series toolholders that accept CNMG-style inserts with clamp or pin retention.

The machine spindle must be fully stopped and the toolholder secured in the turret before seating or indexing the insert. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not overtighten the clamp screw, as this can chip the insert or damage the seat. Inspect the insert pocket and locating pin for chips or debris before seating a new cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: CNMG432MN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120408MN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Layers\u003c\/strong\u003e: TiN, Al2O3, TiCN (multilayer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80-degree included angle)\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\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MN\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: 12.9 mm (0.5077 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1691 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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\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, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7026401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730693980466,"sku":"7026401","price":37.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8daa6f0bec346ae6c087773aea4c063a.jpg?v=1788721466","url":"https:\/\/voomisupply.com\/products\/kennametal-7026401-cnmg432mn-kcp25c-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
