It carries the DFR insert style with an MD chipbreaker geometry and is manufactured to grade KC7140, a PVD-applied TiN and TiCN multilayer coating optimized for cutting performance and tool life. The insert measures 0.4236 inches in length, 0.2906 inches in width, and 0.1492 inches in thickness, with a corner radius of 0.0157 inches (0.40 mm). It fits a 0.1122-inch hole diameter and carries an insert size designation of 040304. Installation is performed by machinists and tooling specialists working with indexable drill bodies on CNC and manual machining equipment.\u003c\/p\u003e\u003cp\u003eThis insert is suited for drilling operations in ferrous and non-ferrous materials where wear resistance and edge stability are priorities. The KC7140 grade with PVD TiN and TiCN coating is rated for material grades C5 and C6, making it applicable to a range of steel and cast-iron cutting scenarios. The MD chipbreaker geometry supports chip control in through-hole and blind-hole drilling. This part is sold individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDFR insert style with MD chipbreaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eKC7140 PVD-applied TiN and TiCN multilayer coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate rated for material grades C5 and C6\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0157 inches (0.40 mm) for edge strength and finish quality\u003c\/li\u003e\n\u003cli\u003eInsert size 040304 with 0.1122-inch mounting hole diameter for precise indexable body fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for indexable drill bodies accepting DFR-style inserts with insert size 040304 and a 0.1122-inch hole diameter.

Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and clamping screw for wear or damage prior to seating a new insert. Do not mix insert grades or styles within a multi-insert drill body unless the body manufacturer explicitly permits it.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DFR\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: KC7140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eInsert Size\u003c\/strong\u003e: 040304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.4236 inches (10.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.2906 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1492 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1122 inches (2.85 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 3015440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51745789247794,"sku":"3015440","price":290.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ab76d8b915902fe5378f13eff7697b8.jpg?v=1788865178","url":"https:\/\/voomisupply.com\/products\/kennametal-3015440-indexable-drill-insert-kc7140-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
