It features a square insert shape with a 90-degree included angle, a 0.0469-inch (1.20 mm) corner radius, and a 0.5-inch inscribed circle. The insert is CVD-coated with a three-layer TiN, TiCN, and Al2O3 stack, providing thermal resistance and wear protection during interrupted and continuous milling cuts. At 0.1875 inches thick and weighing approximately 0.02 pounds, it is designed for screw-held toolholders. Licensed machinists and CNC mill operators install this insert in compatible SDET-series milling bodies.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling applications across a broad range of workpiece materials, including steel, stainless steel, cast iron, superalloys, and titanium, corresponding to ISO material groups P, M, K, and S. The GB2 chip breaker geometry is designed to control chip formation across these varying material hardnesses and feed conditions. Typical applications include face milling, shoulder milling, and general-purpose milling operations where a right-hand, positive-relief insert geometry is required. The 15-degree relief angle supports reduced cutting forces and improved surface finish on difficult-to-machine materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate in KCPK30 grade for toughness and wear resistance in steel and superalloy milling\u003c\/li\u003e\n  \u003cli\u003eCVD three-layer coating: TiN, TiCN, and Al2O3 for thermal barrier and crater wear resistance\u003c\/li\u003e\n  \u003cli\u003eSquare SDET insert shape with 90-degree included angle and GB2 chip breaker geometry\u003c\/li\u003e\n  \u003cli\u003e0.0469-inch corner radius for controlled edge engagement and surface finish\u003c\/li\u003e\n  \u003cli\u003e15-degree relief angle reduces cutting forces on stainless steel, cast iron, and titanium\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation; screw-held insert mounting for positive location in the pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SDET-series milling cutter bodies that accept square screw-held inserts with a 0.5-inch inscribed circle, 0.1875-inch thickness, and a 0.1732-inch hole diameter.

Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly in the pocket and torque the clamping screw to the toolholder manufacturer's specification using a calibrated torque wrench. Inspect the pocket seat and screw threads for wear or debris before reinstalling to maintain proper insert location and cutting geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SDET120412PDERGB2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCPK30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SDET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 433\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (range: 0.5000 to 0.5100 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (range: 0.1850 to 0.2000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0469 inches (1.20 mm)\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: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GB2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, TiCN, Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1, C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Groups\u003c\/strong\u003e: P, M, K, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 0.02 pounds\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: 2390299\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750658310450,"sku":"2390299","price":193.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b0586e9475da0787b6472e09cf8fddb.jpg?v=1788917966","url":"https:\/\/voomisupply.com\/products\/kennametal-2390299-milling-insert-kcpk30-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
