Manufactured in the SPPX insert style with an MD chipbreaker, this insert carries the KCPK10 grade and a CVD-applied TiCN plus Al2O3 coating for high wear resistance and thermal stability. The inscribed circle measures 0.494 inches with a thickness of 0.1875 inches and a corner radius of 0.0469 inches. It is intended for installation in compatible indexable drill bodies and is typically fitted by machinists and CNC operators in production or job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling applications in ferrous and alloy workpiece materials where coating durability and edge retention are critical. The MD chipbreaker geometry promotes effective chip control across a range of feed rates and cutting depths. Applications span general-purpose drilling on CNC machining centers and lathes with live tooling in both high-volume production and precision component work. The KCPK10 grade with CVD TiCN and Al2O3 multilayer coating is well matched to steel and cast iron drilling at moderate to high cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSPPX insert style with MD chipbreaker for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCVD-applied TiCN plus Al2O3 multilayer coating for wear and thermal resistance\u003c\/li\u003e\n  \u003cli\u003e0.494 inch inscribed circle with 0.0469 inch corner radius for defined edge geometry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate in manufacturer grade KCPK10\u003c\/li\u003e\n  \u003cli\u003eInsert size designation 120412 for toolholder compatibility reference\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.1811 inches for mounting in the drill body pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit indexable insert for drill bodies accepting SPPX-style inserts with an insert size designation of 120412.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician with the spindle fully powered down and the machine in a locked-out state per applicable machine safety procedures. Seating surfaces on the drill body pocket should be cleaned of chips and debris before installing the insert. Use the appropriate torx or hex wrench to torque the clamping screw to the drill body manufacturer specification — do not over-torque or substitute fasteners. Inspect the insert and pocket for seating contact before returning the tool to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPPX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCPK10\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 plus Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: MD\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: 0.012 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: 4042904\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730228183346,"sku":"4042904","price":221.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3064768f5290b14fd13c2d882ae1503.jpg?v=1788713688","url":"https:\/\/voomisupply.com\/products\/kennametal-4042904-indexable-drill-insert-sppxmd-kcpk10","provider":"Voomi Supply","version":"1.0","type":"link"}
