Built from high speed steel with a coated finish, it delivers reliable performance in general-purpose drilling tasks. The bit features a 1-21\/64 inch cutting diameter (1.3281 inches decimal) paired with a 1\/2 inch Weldon shank, making it compatible with standard 1\/2 inch chuck capacity portable drills. The 118-degree standard point angle provides a versatile entry geometry suited to a wide range of workpiece materials. A right-hand spiral flute configuration efficiently clears chips during operation.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in portable drilling setups across fabrication, maintenance, and mechanical trade applications. The Weldon shank with three flats resists slippage under torque, making it well suited for high-load drilling in alloy steel, carbon steel, cast iron, and wood. The reduced shank design allows a larger-diameter bit to be driven by a 1\/2 inch capacity drill chuck, extending the usable range of standard portable equipment without requiring a larger drive tool. It belongs to the Series 190F product family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-21\/64 inch cutting diameter (1.3281 inches decimal) with tight tolerance: +0.0000 to -0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch Weldon shank with three flats for positive anti-slip grip\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry on steel, cast iron, and wood\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, two-flute configuration for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eReduced shank design allows use with standard 1\/2 inch chuck portable drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with portable drills equipped with a 1\/2 inch chuck capacity.
