It features a 23\/32 inch cutting diameter with a 1\/2 inch Weldon flat shank, allowing it to seat securely in milling-style chucks and reducing slippage under load. The 118-degree standard point angle is a general-purpose geometry suited for a wide range of metalworking and fabrication tasks. Overall length is 6 inches with a 3-inch flute length, and the bit is finished with a black oxide coating that provides mild corrosion resistance and reduces friction during cutting. This bit is installed by machinists, maintenance techs, and fabricators working in shop or field environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in drill presses, milling machines, and magnetic drills equipped with Weldon-style tool holders. The 1\/2 inch reduced shank allows a larger cutting diameter to be run in a standard 1\/2 inch chuck without requiring a larger spindle bore. Typical applications include structural steel fabrication, general metalworking, and maintenance drilling in industrial settings. The right-hand spiral flute configuration handles standard CW-rotation spindles found on most production equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e23\/32 inch cutting diameter with 0.7188 inch decimal equivalent for precise job planning\u003c\/li\u003e\n\u003cli\u003e1\/2 inch Weldon flat shank with 3 flats for positive chuck engagement and reduced bit walk\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle suitable for low and medium tensile strength metals\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild lubricity and corrosion resistance during service\u003c\/li\u003e\n\u003cli\u003e3-inch flute length supports drilling up to 3 inches deep in a single pass\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for use with standard CW-rotation spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Weldon-style tool holders and drill chucks accepting a 1\/2 inch shank diameter.
