The cutting diameter measures 1-5\/32 inches (1.1562 inches decimal) while the shank reduces to 1\/2 inch, allowing the bit to fit standard 1\/2-inch chucks despite its larger cutting diameter. Built from high speed steel with a coated finish, the 55474 carries a 118-degree standard point angle and a right-hand spiral flute geometry. Overall length is 6 inches with a 3-1\/8-inch flute length. Series 190 construction targets demanding production and field drilling environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for portable drilling operations across residential, commercial, and light industrial applications. It handles a broad range of workpiece materials including wood, alloy steel, carbon steel, and cast iron. The reduced shank design makes it practical for use with 1\/2-inch chuck drills and drill presses where a full 1-5\/32-inch shank would not fit. Two spiral flutes clear chips efficiently during through-hole and blind-hole drilling. No coolant system is required for typical use cases within this bit's intended application range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCutting diameter of 1-5\/32 inches (1.1562 inches) with a reduced 1\/2-inch straight-cylindrical shank\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry and centering\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles alloy steel, carbon steel, cast iron, and wood\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends cutting edge life under repeated use\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 3-1\/8-inch flute length suits most portable and bench drill setups\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 any 1\/2-inch chuck portable drill or drill press.
