With a 0.625-inch inscribed circle, 0.234-inch thickness, and a 0.0469-inch corner radius, this insert is engineered for precision indexable drilling applications where controlled chip evacuation and edge stability are critical. The HP chipbreaker geometry promotes efficient chip flow in moderate-to-high feed drilling operations. The KCU40 grade provides a balance of wear resistance and toughness suited to demanding hole-making conditions in steel and similar workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in indexable drill bodies that accept SPPX-geometry inserts. Typical applications include through-hole and blind-hole drilling on CNC machining centers and turning centers in production shop environments. The insert size designation is 15T512. It is installed and replaced by machinists and toolroom technicians maintaining indexable drill tooling assemblies. The PVD TiN\/TiAlN coating extends tool life in interrupted cuts and at elevated cutting speeds compared to uncoated carbide.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSPPX insert style with HP chipbreaker geometry for controlled chip formation during drilling\u003c\/li\u003e\n  \u003cli\u003eKCU40 solid carbide grade offering a balance of edge toughness and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiN\/TiAlN multilayer coating for extended tool life at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e0.625-inch inscribed circle and 0.234-inch thickness for precise fit in compatible drill bodies\u003c\/li\u003e\n  \u003cli\u003e0.0469-inch corner radius reduces stress concentration at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eInsert size 15T512 for straightforward replacement and inventory identification\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 15T512 insert size designation and a 0.217-inch hole diameter seating requirement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Disengage machine power and lock out the spindle before removing or seating inserts. Use the manufacturer-specified torx or hex key to seat the insert clamp screw — do not overtighten, as carbide inserts are brittle and susceptible to fracture under excessive clamping force. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert to ensure proper contact and indexing accuracy.\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\u003eChipbreaker\u003c\/strong\u003e: HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\/TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.234 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: 0.217 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 15T512\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: 0.04 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: 4042944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749775540530,"sku":"4042944","price":227.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58974eae34fc7c6c6d30dcac3dd523ed.jpg?v=1788910342","url":"https:\/\/voomisupply.com\/products\/kennametal-4042944-sppxhp-kcu40-indexable-drill-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
