It carries the KCU25 manufacturer grade, which is suited for demanding drilling applications where heat resistance and edge wear are primary concerns. The insert features a 0.494-inch inscribed circle, a 0.1875-inch thickness, and a 0.0469-inch corner radius. The HP chipbreaker geometry is engineered to promote controlled chip evacuation in deep-hole and through-coolant drilling operations. Licensed machinists, tool-and-die professionals, and CNC operators typically source and apply this insert class.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in indexable drill bodies designed to accept SPPX-style inserts. It is suited for both light and moderate material removal in metal-cutting operations on CNC machining centers and lathes equipped with driven tooling. The KCU25 grade with CVD TiCN and Al2O3 coating performs well in steel and cast-iron applications where elevated cutting temperatures and abrasive wear are common. The 0.1811-inch hole diameter allows secure mounting within the drill body pocket. Typical applications include production drilling in job shops, aerospace component work, and general metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSPPXHP insert style with HP chipbreaker for controlled chip flow in drilling operations\u003c\/li\u003e\n  \u003cli\u003eKCU25 solid carbide grade rated for C2 and C6 material categories\u003c\/li\u003e\n  \u003cli\u003eCVD-applied TiCN and Al2O3 multilayer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e0.494-inch inscribed circle and 0.0469-inch corner radius for precise fit and edge geometry\u003c\/li\u003e\n  \u003cli\u003e0.1811-inch mounting hole diameter for secure seating in compatible drill bodies\u003c\/li\u003e\n  \u003cli\u003eInsert size designation 120412 for cross-reference with tooling catalogs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in indexable drill bodies that accept SPPX-style inserts with a 120412 insert size designation.

Ensure the drill body pocket and seating surfaces are clean and free of chips or debris before seating the insert. Use the correct torque wrench and manufacturer-specified clamping screws — do not substitute fasteners. Always power down and lock out the machine spindle before indexing or replacing inserts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPPXHP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\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: TiCN and Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.494 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1811 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 120412\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.77 inches L x 2.06 inches W x 0.68 inches H\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: 23242105\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: 4040141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733701361970,"sku":"4040141","price":228.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23f0c1aa421bfc923c383a054ae0e55d.jpg?v=1788758482","url":"https:\/\/voomisupply.com\/products\/kennametal-4040141-sppxhp-kcu25-indexable-drill-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
