Built from high speed steel with an oxide coating, the bit runs a standard 118-degree point angle and a 2-flute spiral configuration with a web-thinned, tapered web for reduced entry force. The straight-cylindrical shank seats directly into standard drill chucks without adapters. Overall length is 4-19\/32 inches, with a flute length of 2-15\/16 inches and a maximum drilling depth of 2.441 inches. This is a general-purpose, high-performance tool rated under ANSI and ISO standards and designated to BS and DIN specifications. Machinists, maintenance technicians, and fabrication shops are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe 5058278 is suited for blind-hole drilling and stack drilling applications in cast iron and steel workpieces. The regular spiral and 8xD flute-to-diameter ratio help clear chips efficiently in these materials. The oxide finish provides light lubricity and corrosion resistance during dry or lightly lubricated cutting operations. This bit fits standard production and maintenance drilling tasks in metal fabrication, manufacturing facilities, and industrial maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter O size, 0.3160 inches diameter with h8 diameter tolerance for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust requirements\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for light lubricity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral design rated for blind-hole and stack drilling in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank, 0.3160 inches diameter, compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; designated per BS and DIN specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel workpieces.
