This insert carries the KC7140 manufacturer grade with a TiN and TiCN coating applied via PVD process, targeting improved wear resistance and tool life in steel and cast iron applications. It features an 84-degree trigon shape with an inscribed circle of 10 mm (0.3937 inches), a thickness of 0.1476 inches, and a corner radius of 0.80 mm (0.0315 inches). The HP chipbreaker geometry supports effective chip control at higher feed rates. Installed by machinists and tooling specialists in CNC and manual drilling applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production drilling environments where consistent hole quality and insert longevity are priorities. The DFT insert style with HP chipbreaker is engineered for high-performance drilling into steel and similar workpiece materials. The PVD-applied TiN and TiCN coating layers provide a hard, low-friction surface that resists built-up edge and thermal wear. It is sold individually per package, with a minimum order quantity of 5 units, making it appropriate for toolroom stocking and production replenishment. Insert size designation is 06T308 with a relief angle of 8 degrees.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-feed drilling\u003c\/li\u003e\n\u003cli\u003eKC7140 grade with PVD-applied TiN and TiCN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eHP chipbreaker promotes effective chip evacuation at elevated feed rates\u003c\/li\u003e\n\u003cli\u003e84-degree trigon shape with 0.80 mm corner radius for controlled cutting action\u003c\/li\u003e\n\u003cli\u003e10 mm inscribed circle and 8-degree relief angle optimized for insert drill bodies\u003c\/li\u003e\n\u003cli\u003eInsert size 06T308 with 4.4 mm mounting hole diameter for secure seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in indexable drill toolholders that accept DFT-style trigon inserts with a 06T308 insert size designation and a 4.4 mm hole diameter.

Use the correct torx or hex key driver specified by the toolholder manufacturer to seat the insert and secure the clamping screw to the recommended seating torque as noted in the toolholder documentation. Inspect the insert pocket for debris or damage before seating a new insert. Do not mix insert grades or styles within a multi-insert drill body unless confirmed compatible by the toolholder manufacturer.\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\u003eShape\u003c\/strong\u003e: Trigon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 84 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC7140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 06T308\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: 6.62 mm (0.2606 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.4 mm (0.1732 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0044 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: 1804830\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739539538226,"sku":"1804830","price":189.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3d152face3955a5e1b71b08407d0ac8.jpg?v=1788815954","url":"https:\/\/voomisupply.com\/products\/kennametal-1804830-indexable-drill-insert-kc7140-trigon","provider":"Voomi Supply","version":"1.0","type":"link"}
