Built from solid carbide and finished with a multilayer TiAlN coating at the tip, this bit handles hard and abrasive workpiece materials where high-speed steel tooling falls short. The 140-degree split-point geometry reduces thrust force and improves centering without a pilot hole. At 58.00 mm overall length with a 17.00 mm flute length and a 4.00 mm straight cylindrical shank, the compact stub profile delivers added rigidity for tight-tolerance drilling applications. Coolant-through capability supports chip evacuation and tool life in deeper passes up to 12.00 mm.\u003c\/p\u003e\u003cp\u003eThis bit is sized at 2.80 mm (0.1102 inch) diameter and is designed for use in CNC machining centers, drill presses, and screw machine setups requiring consistent hole quality in metals and hard materials. The stub length format reduces deflection in short-reach drilling scenarios common in production machining, mold work, and precision component manufacturing. It follows DIN 6537K specification and belongs to KENNAMETAL Series B051A-CPG.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN (tip) coating reduces heat buildup and extends tool life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle improves self-centering and reduces entry burr\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip evacuation in deep drilling passes\u003c\/li\u003e\n\u003cli\u003eStub length profile increases rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute, tapered web configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-compatible replacement or standard production drill bit for CNC and screw machine setups requiring a 2.80 mm diameter, DIN 6537K stub-length drill in solid carbide.

Ensure the tool holder or collet is clean and free of debris before seating the shank to maintain runout tolerances. Confirm coolant-through lines are properly connected and pressurized before running the bit at speed. Do not exceed the recommended maximum drilling depth of 12.00 mm per pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.80 mm (0.1102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 58.00 mm (2.2835 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 17.00 mm (0.6693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 12.00 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.45 mm (0.0177 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer (TiN Tip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.014 to 0.000 mm (-0.0006 to 0.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 4148854\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731583172914,"sku":"4148854","price":125.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fe272e6cf40e9027bbea2760627a540_af91bace-1e5a-4b8d-8c26-03c95127af53.jpg?v=1788732815","url":"https:\/\/voomisupply.com\/products\/kennametal-4148854-drill-bit-2-80mm-solid-carbide-140deg","provider":"Voomi Supply","version":"1.0","type":"link"}
