It features a 41\/64 inch (0.6406 inch) cutting diameter paired with a 1\/2 inch Weldon shank, allowing it to fit standard 1\/2 inch chucks even at a larger cutting diameter. The bit is manufactured from high speed steel with a coated finish for added wear resistance. The 118-degree split point promotes accurate starting and reduces walking on entry. With a 6 inch overall length and a 3-1\/8 inch flute length, it provides adequate depth capacity for most production and field drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for portable drilling operations across residential, commercial, and light industrial settings. It is commonly used by tradespeople drilling through carbon steel, alloy steel, cast iron, and wood. The three-flat Weldon shank prevents slipping under torque loads, making it a reliable choice in hand drills and drill presses where positive shank engagement is required. It is sold individually and is part of the CHICAGO-LATROBE 190F series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e41\/64 inch cutting diameter with a diameter tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch Weldon shank with three flats resists rotation under heavy torque loads\u003c\/li\u003e\n  \u003cli\u003e118-degree split point for accurate positioning and reduced thrust on entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life in general-purpose drilling applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral fluting for standard clockwise drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in portable drills and drill presses accepting a 1\/2 inch Weldon shank.
