It features a 3.80 mm diameter, a 140-degree point angle for aggressive penetration and self-centering on hard materials, and a multilayer TiAlN coating that extends tool life under heat and friction. The straight-cylindrical shank measures 6 mm in diameter and seats directly in standard drill chucks or collet holders. Overall length is 74 mm (2.9134 inches) with a 36 mm flute length. This drill is built to DIN 6537K specification and includes through-coolant capability, making it suited for CNC machining centers and automated drilling operations where heat management is critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 5xD flute-to-diameter ratio and two-flute regular spiral design promote efficient chip evacuation in deep-hole applications up to 29 mm drilling depth. Machinists, tool-and-die professionals, and CNC operators working in job shops, fabrication facilities, and production lines will find this bit well suited to demanding short-run and high-volume drilling programs where dimensional accuracy and hole quality are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.80 mm diameter with tolerance of -0.0005 to 0.0000 inches for tight, consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle for fast penetration and reduced thrust on hard metals\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating resists heat buildup and extends cutting life on ferrous and stainless materials\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design compatible with CNC machining centers equipped with internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves rigidity and reduces walking at drill entry\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional conformance for repeatable tool changes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for standard CNC and manual drill press use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement and production-use jobber drill for CNC machining centers, drill presses, and multi-spindle setups using standard straight-shank collet chucks or drill chucks accepting a 6 mm shank diameter.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the drill from the chuck or collet holder. Confirm collet or chuck bore matches the 6 mm straight shank for secure, concentric seating. When using through-coolant, verify coolant pressure and flow rate are within the machine and tooling system specifications before beginning the drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.80 mm (0.1496 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: 74 mm (2.9134 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.4531 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 29 mm (1.1417 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.62 mm (0.0245 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\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 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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.05 pounds\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: 4149190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741350363442,"sku":"4149190","price":156.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ae6ee7358dc8cbd058ea40dc743415e.jpg?v=1788830950","url":"https:\/\/voomisupply.com\/products\/kennametal-4149190-solid-carbide-jobber-drill-3-80mm-140","provider":"Voomi Supply","version":"1.0","type":"link"}
