It carries the DFR insert style with an MD chipbreaker geometry and is manufactured in grade KCU25, a PVD-applied AlTiN-coated carbide grade suited for a wide range of steel and cast iron drilling applications. The insert has an 8 mm (0.3150 inch) inscribed circle, a thickness of 0.1492 inches, and a corner radius of 1\/64 inch (0.0156 inches). The neutral hand orientation makes it compatible with both right- and left-hand toolholders of the appropriate insert pocket style. Machinists and toolroom technicians are the primary installers of this consumable cutting insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in indexable drill bodies that accept DFR-style pockets sized for the 040304 insert size designation. Typical applications include through-hole and blind-hole drilling in ferrous materials such as low-alloy steel, carbon steel, and gray cast iron in both roughing and semi-finish operations. The MD chipbreaker geometry is suited for moderate chip loads and helps control chip formation in interrupted or continuous cuts. This insert is sold individually, with a minimum order quantity of 10 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 PVD AlTiN coating provides thermal resistance and wear protection in steel and cast iron drilling\u003c\/li\u003e\n  \u003cli\u003eMD chipbreaker geometry promotes controlled chip formation during moderate feed-rate drilling\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert accommodates both right- and left-hand DFR-style drill body pockets\u003c\/li\u003e\n  \u003cli\u003e8-degree relief angle reduces flank wear in continuous drilling operations\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate with 0.40 mm corner radius minimizes edge chipping at drill entry and exit\u003c\/li\u003e\n  \u003cli\u003eInsert size 040304 for precise pocket fit and repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement indexable drill insert for indexable drill bodies that accept DFR-style insert pockets in the 040304 insert size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician with the machine in a full lockout\/tagout state before insert indexing or replacement. Use the correct insert screw torque driver specified by the drill body manufacturer to avoid cracking the carbide substrate. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Never use damaged or deformed insert screws, as improper clamping can cause insert movement under cutting loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DFR\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: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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: MD\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: 040304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 8.00 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1492 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.2906 inches\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\u003eHole Diameter\u003c\/strong\u003e: 0.1122 inches (2.85 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.006 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 5067316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732476592434,"sku":"5067316","price":313.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/430799b8830b5298396792b33f80cb8c.jpg?v=1788743324","url":"https:\/\/voomisupply.com\/products\/kennametal-5067316-indexable-drill-insert-kcu25-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
