It features a 2.20 mm (0.0866 inch) diameter, a 140-degree split-point geometry, and a multilayer TiAlN coating for extended tool life under elevated cutting temperatures. The overall length is 58.00 mm (2.2835 inches), with a 4 mm straight-cylindrical shank. Two right-hand spiral flutes provide efficient chip evacuation. This drill is intended for use by machinists and tool-and-die professionals running CNC machining centers or manual drill presses where tight-tolerance hole making is required.\u003c\/p\u003e\u003cp\u003eThe 4149151 is suited for drilling steel, stainless steel, cast iron, and aluminum and non-ferrous materials. The 5xD flute-to-diameter ratio and 14.00 mm (0.5512 inch) maximum drilling depth make it a practical choice for through-hole and blind-hole applications in short-run and high-volume production settings. The coolant-through design supports internal coolant delivery, which is especially beneficial when drilling stainless steel or other work-hardening alloys where heat buildup shortens tool life. Conforms to DIN 6537K specification.\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\u003e140-degree point angle reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating extends tool life at elevated cutting temperatures\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 flutes promote consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds strength at the drill tip\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production tooling option for CNC machining centers and drill presses accepting a 4 mm straight-cylindrical shank, within the 2.00 mm to 3.00 mm drill bit size range per DIN specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following applicable shop safety procedures. Confirm the spindle or chuck is fully stopped and de-energized before inserting or removing the bit. Use a properly sized collet or drill chuck rated for the 4 mm shank diameter to ensure concentricity and prevent runout. When using the coolant-through feature, verify that coolant pressure and flow rate are compatible with the machine spindle before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.20 mm (0.0866 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\u003eMaterial\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\u003eOverall Length\u003c\/strong\u003e: 58.00 mm (2.2835 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 18.00 mm (0.7087 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 14.00 mm (0.5512 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 (1.1024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.35 mm (0.0137 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.5 x 0.8 x 0.8 inches\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: 4149151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743235965234,"sku":"4149151","price":157.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fe272e6cf40e9027bbea2760627a540_1b73fd14-1cc1-4179-8f68-d5241a6d7d59.jpg?v=1788844334","url":"https:\/\/voomisupply.com\/products\/kennametal-4149151-solid-carbide-jobber-drill-2-20-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
