The insert is square in shape with a 90-degree included angle and a right-hand cutting orientation. It measures 0.5 inches inscribed circle diameter and 0.1875 inches thick, with a corner radius of 0.0315 inches (0.80 mm) and a through-hole diameter of 0.1732 inches. The GB2 chip breaker geometry is suited for controlled chip evacuation across a wide range of workpiece materials. Screw-type holding secures the insert in compatible milling toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for milling applications on steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material groups P, M, K, and S. The KCPK30 grade combined with the CVD multilayer coating targets moderate to demanding cutting conditions where wear resistance and thermal stability are priorities. It is appropriate for face milling, shoulder milling, and similar operations in manufacturing environments where consistent tool life across varied workpiece materials is required. Installation is performed by qualified machinists or tooling technicians in CNC and manual milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD multilayer TiN, TiCN, and Al2O3 coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eKCPK30 manufacturer grade suited for steel, stainless steel, cast iron, superalloys, and titanium (ISO P, M, K, S)\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and GB2 chip breaker geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation with screw-type insert holding method\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0315 inches (0.80 mm) for controlled edge engagement\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 0.5 inches and thickness of 0.1875 inches (Insert Size Code 43)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SDPT-series milling toolholders that accept a square insert with a 0.5-inch inscribed circle, 0.1875-inch thickness, and 0.1732-inch screw hole diameter.

Use the correct torx or hex key specified by the toolholder manufacturer to reach the recommended clamp torque for screw-type insert retention. Inspect the toolholder seat for debris or damage before seating the insert. Follow shop safety protocols and machine tool manufacturer guidelines during any tooling changeover.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SDPT1204PDSRGB2\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 Series\u003c\/strong\u003e: SDPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 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 Material\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\u003eWeight\u003c\/strong\u003e: 0.0163 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: 2405389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732940390706,"sku":"2405389","price":189.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f14fd254a6211e7ab5bad9beac30812a_fc07295c-49f0-43bc-b8dd-fb335ca8f4a3.jpg?v=1788749201","url":"https:\/\/voomisupply.com\/products\/kennametal-2405389-milling-insert-kcpk30-solid-carbide-square","provider":"Voomi Supply","version":"1.0","type":"link"}
