It features a standard 118-degree split point with web thinning for easier starting and reduced walking on entry. The 2-flute spiral design with a regular helix and tapered web configuration provides efficient chip evacuation in general-purpose drilling applications. With an overall length of 3.625 inches and a straight-cylindrical shank, this bit is sized for use in standard drill chucks. It is suited for machinists, maintenance technicians, and trade professionals who require reliable, repeatable hole sizing in non-ferrous and general-purpose materials.\u003c\/p\u003e\n\u003cp\u003eThe 44278 is designed for general-purpose drilling in non-ferrous metals and similar materials. The 3.625-inch overall length and 2.4375-inch flute length make it practical for bench drill presses, hand drills, and drill-press setups in shop and field environments. The straight-cylindrical shank seats securely in standard three-jaw and keyless chucks. It conforms to DIN 338 standards, making it a recognized specification for jobber-length tooling across a wide range of trade and industrial drilling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size No. 8 with 0.1990-inch decimal diameter and tight diameter tolerance of -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for clean entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for non-ferrous metals and general shop use\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute design with tapered web for efficient chip clearing\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 jobber-length standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.1990-inch straight-cylindrical shank.
