It measures 2.40 mm in diameter with a 140-degree point angle and a multilayer TiAlN coating that extends tool life in abrasive and heat-intensive applications. The overall length is 58.00 mm (2.28 inches), with a straight cylindrical shank diameter of 4 mm (0.375 inches). Featuring two right-hand spiral flutes and a tapered web configuration, it is built for consistent chip evacuation and accurate hole entry. This drill is sold as a single unit and targets machinists and tool-and-die professionals working in production environments.\u003c\/p\u003e\u003cp\u003eThe 4149154 is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. Its 5xD flute-to-diameter ratio makes it appropriate for moderate-depth holes in both manual and CNC machine tool setups. The coolant-through design supports internal coolant delivery, which is especially effective in high-speed CNC applications where heat buildup and chip clearing are concerns. The DIN 6537K specification designation confirms conformance to a recognized European standard, making this bit a common choice in precision machining shops working to tight tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating reduces heat buildup and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle provides aggressive, self-centering entry on hard metals\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole and high-speed applications\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute geometry promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for dimensional accuracy and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement jobber drill compatible with standard straight-shank drill chucks and collets accepting a 4 mm (0.375 inch) shank diameter, suitable for CNC machining centers and conventional drill presses used on steel, stainless steel, cast iron, and non-ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists familiar with proper toolholder torque and runout specifications for their machine tool. Power down and lock out the spindle before inserting or removing the bit from the chuck or collet. Verify shank seating and chuck concentricity before beginning a cut, as runout directly affects hole diameter tolerance and tool life. Internal coolant lines should be inspected and confirmed clear before engaging the coolant-through feature.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.40 mm (0.0945 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 58.00 mm (2.28 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22.00 mm (0.866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 28 mm (1.10 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 17.00 mm (0.669 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.38 mm (0.015 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 4149154\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741798400306,"sku":"4149154","price":156.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fe272e6cf40e9027bbea2760627a540_55717959-439f-4499-8ed1-af7205bb7ebb.jpg?v=1788833534","url":"https:\/\/voomisupply.com\/products\/kennametal-4149154-solid-carbide-jobber-drill-2-40-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
