It features a three-layer PVD coating stack of TiN, TiCN, and TiN applied over a solid carbide substrate, delivering wear resistance and thermal stability across demanding cutting applications. The insert measures 3\/8 inches in inscribed circle diameter and 5\/32 inches thick, with an 11-degree relief angle and a neutral hand orientation. A center-screw holding method locks the insert securely in the toolholder. This insert is used by machinists and tooling specialists in CNC milling operations targeting steel, stainless steel, superalloys, and titanium workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling operations in both production shop and job-shop environments where steel (ISO P), stainless steel (ISO M), and superalloys or titanium (ISO S) are the primary workpiece materials. The RPGB series round insert geometry provides a continuous cutting edge that distributes cutting forces evenly, making it well-suited for profiling, copy milling, and light-to-medium stock removal passes. It fits toolholders designed for the RPGB09T300 insert pocket geometry. Typical applications include aerospace component work involving titanium and nickel-based superalloys as well as general-purpose stainless and alloy steel milling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiN \/ TiCN \/ TiN multilayer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRound RPGB insert shape with continuous cutting edge for profile and copy milling\u003c\/li\u003e\n  \u003cli\u003e11-degree relief angle reduces cutting forces and minimizes workpiece heat buildup\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits both right-hand and left-hand toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp holding method provides positive insert location and repeatable indexing\u003c\/li\u003e\n  \u003cli\u003eRated for ISO P, M, and S material grades covering steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders with RPGB09T300-style insert pockets.

Use the correct torque driver for the screw-clamp fastener as specified by the toolholder manufacturer — do not over-torque or use makeshift tools. Inspect the insert pocket seat and clamping screw for debris or damage before seating a new insert. Follow the toolholder manufacturer's setup sheet for proper insert orientation and projection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: RPGB09T300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style \/ Series\u003c\/strong\u003e: RPGB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN \/ TiCN \/ TiN (multilayer PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches (5\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Range\u003c\/strong\u003e: 0.3500 to 0.4000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Range\u003c\/strong\u003e: 0.1500 to 0.1750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0051 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 5)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: 1157494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732050739506,"sku":"1157494","price":237.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61a751b1395c5de4e7fdec80cb925d1d.jpg?v=1788738674","url":"https:\/\/voomisupply.com\/products\/kennametal-1157494-rpgb09t300-round-milling-insert-kc725m","provider":"Voomi Supply","version":"1.0","type":"link"}
