Built from carbide with a TiN (titanium nitride) coating applied via PVD process, this insert delivers wear resistance and edge retention across a range of ferrous and non-ferrous workpiece materials. The insert carries a KC7140 manufacturer grade designation, features a GD chipbreaker, and has a neutral hand orientation. With a 1\/32 inch corner radius and an 84-degree included angle, it is suited for through-hole and blind-hole drilling operations where controlled chip formation is required. Installation and replacement are handled by machining professionals and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis insert is applied in CNC turning centers and machining centers running indexable insert drill bodies that accept the DFT insert style with an insert size designation of 070408. It is appropriate for production drilling in job shop and manufacturing environments where repeatability and insert indexability reduce downtime. The 12.00 mm inscribed circle and 4.4 mm hole diameter correspond to standard DFT-body seating geometry. The neutral hand designation makes it usable in standard right-hand drill body configurations without mirrored or handed positioning requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with PVD-applied TiN coating for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003eKC7140 grade optimized for consistent performance in indexable drill applications\u003c\/li\u003e\n\u003cli\u003eGD chipbreaker geometry promotes controlled chip evacuation in drilling operations\u003c\/li\u003e\n\u003cli\u003e84-degree included angle with 1\/32 inch corner radius for defined cutting geometry\u003c\/li\u003e\n\u003cli\u003eNeutral hand insert fits standard right-hand DFT drill body configurations\u003c\/li\u003e\n\u003cli\u003eInsert size 070408 with 12.00 mm inscribed circle for precise body seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENNAMETAL DFT-style indexable drill bodies that accept insert size 070408 with a 4.4 mm mounting hole diameter and a 12.00 mm inscribed circle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert replacement is performed by machining technicians with the machine powered down and the spindle locked. Use the appropriate Torx or hex key driver as specified by the drill body manufacturer to seat and torque the clamping screw. Inspect the insert pocket and clamping screw threads for damage or debris before installing a new insert. Do not run a visibly chipped or worn insert, as insert failure under load can damage the drill body seat.\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: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC7140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 84 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: GD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 070408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.313 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 0.96 inches W x 0.51 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 6178235\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736005443890,"sku":"6178235","price":214.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f94cb0e6474de00f44f3662e06416494_ca285bba-0941-4477-b811-2bfc4a114593.jpg?v=1788775371","url":"https:\/\/voomisupply.com\/products\/kennametal-6178235-indexable-drill-insert-dftgd-kc7140","provider":"Voomi Supply","version":"1.0","type":"link"}
