Built from high-speed steel with a bright, uncoated finish, it features a parabolic flute geometry and a web-thinned, tapered web configuration that promotes efficient chip evacuation and reduced thrust force. The 130-degree split-point tip provides accurate positioning without a center punch on most materials. Overall length is 2.75 inches with a flute length of 1.53 inches, and the straight-cylindrical shank measures 0.1339 inches in diameter. This bit is sized to 3.4 mm, equivalent to 0.1339 inches decimal, and conforms to DIN 338 standards. It is suited for use in CNC machining centers, drill presses, and hand-held power drills.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated primarily for aluminum and non-ferrous materials, as indicated by the K, N, and P workpiece material codes, though its high-speed steel construction also handles a range of general-purpose drilling tasks. The Series 549 designation places it in GUHRING's high-performance jobber drill family, conforming to DIN 338 geometry specifications. It ships as a single unit and is appropriate for machine shops, maintenance technicians, and tool cribs requiring small-diameter precision drilling in production or repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.4 mm diameter (0.1339 inches decimal) with a diameter tolerance of -0.018 to 0.000 mm for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design with web thinning for improved chip flow and reduced cutting resistance\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle for self-centering entry on aluminum and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated high-speed steel construction suitable for general-purpose and light-production drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 specification for jobber length geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or direct-use jobber drill conforming to DIN 338 standards, compatible with any drill press, CNC machining center, or hand-held power tool equipped with a standard chuck accepting a 0.1339-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a machinist or qualified technician familiar with rotating cutting tool safety.
