This trigon-shaped insert carries a KCU40 manufacturer grade and features a PVD-applied dual-layer TiN and TiAlN coating for thermal protection and extended tool life in demanding metal-cutting operations. The inscribed circle measures 12 millimeters (0.4724 inches), the insert thickness is 0.1875 inches, and the corner radius is 0.0313 inches (0.79 mm). It is a neutral-hand insert with an 84-degree included angle and a 9-degree relief angle. Cutting tool specialists and machining technicians install this insert in toolholders sized for the DFTHP seat geometry.\u003c\/p\u003e\u003cp\u003eThis insert is suited for drilling operations in ferrous and similar materials where a trigon geometry paired with an HP chipbreaker delivers predictable chip evacuation. It fits applications in production machining environments, both manual and CNC, where repeatable insert indexing is required. The insert size designation is 070408, and the through-hole diameter is 0.1732 inches (4.4 mm), used for the clamping screw. This insert is sold individually but carries a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDFTHP insert style with 84-degree trigon shape and HP chipbreaker for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eKCU40 grade solid carbide substrate with PVD-applied TiN and TiAlN dual-layer coating\u003c\/li\u003e\n\u003cli\u003e12 mm inscribed circle (0.4724 inches) with insert size designation 070408\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0313 inches (0.79 mm) for edge strength in drilling applications\u003c\/li\u003e\n\u003cli\u003e9-degree relief angle with neutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eMounting hole diameter of 0.1732 inches (4.4 mm) for secure screw-clamp retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for indexable drill toolholders requiring the DFTHP seat geometry with a 12 mm inscribed circle and 070408 insert size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machining technician or cutting tool specialist. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to the toolholder manufacturer's seating procedure — do not overtighten the clamping screw, as this can fracture the carbide insert. Inspect the insert pocket seat and clamping screw for wear or debris 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: DFTHP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Trigon (84-degree included angle)\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\u003c\/strong\u003e: TiN and TiAlN (PVD process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 070408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\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\u003eRelief Angle\u003c\/strong\u003e: 9 degrees\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\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.3126 inches (7.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.016 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 (minimum order quantity: 5)\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: 5066199\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728768270642,"sku":"5066199","price":212.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7872c95c5caff94397032ccdde695b1_b173ba58-755c-4716-8209-818ebf6c529f.jpg?v=1788696027","url":"https:\/\/voomisupply.com\/products\/kennametal-5066199-indexable-drill-insert-dfthp-kcu40","provider":"Voomi Supply","version":"1.0","type":"link"}
