It features a 135-degree split point with web thinning, which reduces the force needed to start a cut and helps center the bit without a pilot hole. The straw oxide finish provides a degree of lubricity and corrosion resistance during drilling operations. At 3.1563 inches overall length with a 1.8438-inch flute, this bit fits standard drill chucks and is suited for use in hand drills, drill presses, and CNC drilling setups where a straight cylindrical shank is required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for cutting steel, cast iron, non-ferrous metals, and superalloys, making it a practical choice for HVAC fabrication, plumbing rough-in, electrical panel work, and general metalworking. The 2ACO series is manufactured to DIN 338 and ANSI standards, confirming dimensional consistency across the series. The 4.70 mm diameter corresponds to 0.1850 decimal inch, which falls in the 0.1500 to 0.2000 inch size range. Typical users include machinists, maintenance technicians, and trade professionals who need a reliable, heavy-duty general-purpose drill bit for metal drilling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction rated for heavy-duty drilling in steel and difficult alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering starts and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish for added lubricity and surface protection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute, 2-flute configuration for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard 3-jaw drill chucks without an adapter\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 and ANSI standards for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, cast iron, non-ferrous metals, and superalloys per workpiece material codes P, M, K, N, and S.
