The bit measures 27\/32 inches (0.8438 inches decimal) in cutting diameter and runs a 1\/2-inch straight-cylindrical shank, allowing it to seat in standard 1\/2-inch chucks even though the cutting diameter is larger. Constructed from high speed steel with a coated finish, this Series 190 bit handles general-purpose drilling across a range of workpiece materials. It is a two-flute, right-hand cut design with a 118-degree standard point angle and a regular spiral flute configuration. Machinists, maintenance technicians, and general tradespeople reach for this bit when a full-shank bit of this diameter would not fit the available tooling.\u003c\/p\u003e\n\u003cp\u003eThe 55454 is suited for portable drilling applications where a reduced shank is necessary to bridge the gap between a large cutting diameter and a standard 1\/2-inch chuck. Primary workpiece material is wood, with secondary capability in alloy steel, carbon steel, cast iron, and wood composites. The 6-inch overall length and 3-1\/8-inch flute length give it enough reach for most through-hole and deep-hole tasks in fabrication, maintenance, and field service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced shank design: 27\/32-inch cutting diameter steps down to a 1\/2-inch shank for use in standard chucks\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling in wood, steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute regular spiral for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eShank length of 2.25 inches provides stable chuck engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with portable drills and drill presses fitted with 1\/2-inch chucks.
