The insert carries the DFTHP designation, combining the DFT insert style with an HP chipbreaker geometry optimized for high-performance drilling applications. It is manufactured in grade KCU40 with a PVD-applied TiN and TiAlN dual-layer coating that improves wear resistance and thermal stability. With an 84-degree trigon shape, a 0.3150-inch (8 mm) inscribed circle, and a 1\/32-inch corner radius, this insert suits precision drilling operations in ferrous and non-ferrous materials. Installation is performed by qualified machinists and tooling specialists in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is intended for indexable drill bodies that accept DFT-style trigon inserts in size 05T308. It is applicable in CNC machining centers, drill presses, and turning centers equipped with appropriate toolholders. The HP chipbreaker geometry is suited to through-hole and blind-hole drilling where controlled chip evacuation is critical. The neutral hand designation makes it compatible with standard right-hand drill body setups. This insert is sold individually with a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU40 solid carbide grade with PVD-applied TiN and TiAlN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eHP chipbreaker geometry engineered for controlled chip formation in drilling operations\u003c\/li\u003e\n\u003cli\u003e84-degree trigon (triangular) insert shape, size 05T308\u003c\/li\u003e\n\u003cli\u003e0.3150-inch (8 mm) inscribed circle with 1\/32-inch (0.79 mm) corner radius\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for standard right-hand drill body compatibility\u003c\/li\u003e\n\u003cli\u003eRelief angle of 9 degrees for positive cutting action and reduced thrust force\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for indexable drill bodies that accept DFT-style trigon inserts in size 05T308 with a 3.4 mm mounting hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the drill body and spindle are fully de-energized and stationary before seating or removing the insert. Use the correct torque wrench and insert screw specified by the drill body manufacturer — do not over-torque the clamping screw, as this can fracture the carbide substrate. Inspect the insert pocket for wear or debris before installation to ensure proper seating and repeatability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DFT\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 and TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Trigon (84 degrees included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 05T308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3150 inches (8 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1476 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.2083 inches (5.29 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 9 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1340 inches (3.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.004 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5066193\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728440492338,"sku":"5066193","price":151.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7872c95c5caff94397032ccdde695b1_c519639b-e033-44e7-ab25-86a9cdf787cb.jpg?v=1788691212","url":"https:\/\/voomisupply.com\/products\/kennametal-5066193-indexable-drill-insert-kcu40-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
