It carries the ANSI designation RNMG32RN and the ISO code RNMG090300RN. The insert is manufactured from solid carbide with a multilayer CVD coating sequence of TiCN, Al2O3, and TiOCN applied via MTCVD process, resulting in the KCP25B grade. This grade delivers moderate wear resistance combined with toughness, making it well-suited for interrupted and continuous cuts in steel and cast iron. Eight usable cutting edges per insert are available through a neutral-hand, full-radius round shape with a 0.1875-inch corner radius.\u003c\/p\u003e\n\u003cp\u003eThe 5425596 targets production and job-shop environments where a single insert geometry must handle roughing and medium machining passes without a toolholder changeover. Primary workpiece materials are steel (ISO P) and cast iron, with the grade also rated for aluminum and non-ferrous materials (ISO N) at moderate to high toughness demands. The RN chip breaker geometry controls chip flow during both heavier roughing passes and mid-range material-removal rates. The insert is held by clamp or pin in any KENLOC-compatible round-insert toolholder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRNMG32RN geometry: full-radius round shape with 0.1875-inch corner radius and 0.375-inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eKCP25B grade with multilayer MTCVD coating (TiCN, Al2O3, TiOCN) for wear resistance and toughness balance\u003c\/li\u003e\n  \u003cli\u003e8 usable cutting edges per insert; neutral hand suits both right- and left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eRN chip breaker rated for roughing and medium machining applications\u003c\/li\u003e\n  \u003cli\u003eMulti-use geometry supports turning, facing, and boring without insert change\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge preparation reduces chipping on entry and exit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series round-insert toolholders accepting RNMG32 (ANSI) or RNMG090300 (ISO) inserts with clamp or pin holding.

Seat the insert fully into the pocket before torquing the clamping screw or engaging the pin to avoid micro-fracture at the cutting edge. Inspect the toolholder pocket for wear, chips, or debris before seating a new insert. Do not use damaged or chipped inserts, as edge failure under cut can create unsafe projectile conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: RNMG32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: RNMG090300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: RNMG32RN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: R - Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.250 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: RN (Roughing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiOCN (Multilayer MTCVD CVD)\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: MTCVD\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Cast Iron\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 5425596\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731900563762,"sku":"5425596","price":142.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17304dbb02fc7b1f10a5c5c00dbc14b9_2612ecd5-9c19-4c77-9e24-c2a9324bb9c7.jpg?v=1788736301","url":"https:\/\/voomisupply.com\/products\/kennametal-5425596-round-turning-insert-3-8-inch-ic-kcp25b","provider":"Voomi Supply","version":"1.0","type":"link"}
