The insert carries the SPPX style geometry with an MD chipbreaker and is manufactured to the KCU40 grade, a PVD-coated carbide grade finished with a TiN and TiAlN multilayer coating for improved wear resistance and thermal stability. The inscribed circle measures 0.619 inches, thickness is 0.234 inches, and the corner radius is 0.0469 inches. Insert size designation is 15T512. Machinists and tool-room technicians working in metalcutting operations will recognize this insert as a standard peripheral or center position replacement for compatible Kennametal indexable drill bodies.\u003c\/p\u003e\u003cp\u003eThis insert is suited for indexable drill applications in metal-cutting environments including production machining, job shops, and general manufacturing. The PVD TiN and TiAlN coating combination performs well in ferrous and non-ferrous workpiece materials where controlled chip formation and edge durability are priorities. The MD chipbreaker geometry supports chip evacuation in through-hole and blind-hole drilling operations. This insert is sold individually, with a minimum order quantity of 10 units per transaction.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSPPX insert style with MD chipbreaker geometry for controlled chip formation during drilling\u003c\/li\u003e\n\u003cli\u003eKCU40 carbide grade with PVD-applied TiN and TiAlN multilayer coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 0.619 inches and insert size 15T512 for precise tool body fit\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0469 inches for edge strength at the cutting corner\u003c\/li\u003e\n\u003cli\u003eThickness of 0.234 inches with a hole diameter of 0.217 inches for secure clamping in the drill body pocket\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate provides rigidity and dimensional stability under cutting loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style indexable insert replacement for SPPX-style insert drill bodies accepting a 15T512 insert size with a 0.217-inch hole diameter.

De-energize and lock out the machine spindle before changing inserts. Use the correct torx or hex key to the drill body manufacturer's specified seating procedure — do not over-torque the clamping screw, as carbide inserts are brittle and can fracture under clamp stress. Inspect the insert pocket seat and clamping screw for wear or damage before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPPX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 15T512\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: MD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU40\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: TiN and 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: 0.619 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\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4042943\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51752325644594,"sku":"4042943","price":445.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/271561c45a0e41579072961f845ec4de.jpg?v=1788927467","url":"https:\/\/voomisupply.com\/products\/kennametal-4042943-indexable-drill-insert-sppxmd-kcu40","provider":"Voomi Supply","version":"1.0","type":"link"}
