Built from high speed steel, this bit features a 55\/64 inch (0.8594 inch decimal) cutting diameter paired with a 1\/2 inch Weldon shank for secure chuck engagement. The 118-degree split point promotes fast, accurate starts with minimal walking on entry. With a 6 inch overall length and 3-1\/8 inch flute length, this bit is suited to general-purpose production and service drilling where a reduced shank design is required to fit standard 1\/2 inch chucks.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in portable drilling setups on job sites and in shop environments. It performs across a broad range of workpiece materials including wood, alloy steel, carbon steel, and cast iron. The 190F Series designation places it in a line of general-purpose high speed steel tooling. It is a practical fit for electricians, plumbers, HVAC technicians, ironworkers, and maintenance professionals who regularly drill through structural and finish materials with a standard 1\/2 inch portable drill.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e55\/64 inch cutting diameter (0.8594 inch decimal) with a diameter tolerance of +0.0000 to -0.0012 inches for consistent hole size\u003c\/li\u003e\n  \u003cli\u003e118-degree split point for fast starts and reduced thrust on entry\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch Weldon shank with 3 flats for positive drive and no-slip chuck engagement\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across wood, carbon steel, alloy steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral fluting for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCoated finish to support extended service life in general-purpose applications\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 portable or bench-mounted drill equipped with a standard 1\/2 inch chuck or 1\/2 inch Weldon-style toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by trade professionals using a standard 1\/2 inch drill or drill press with a Weldon-compatible chuck or toolholder.
