It features a standard 118-degree split point, a regular spiral flute, and a straight-cylindrical shank. Overall length is 4.125 inches with a flute length of 2.875 inches. The bit is web-thinned with a tapered web configuration for improved chip evacuation and reduced thrust. It is suited for general-purpose drilling applications performed by machinists, maintenance technicians, and trade professionals working in production or field environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling into a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It carries ANSI standards compliance and falls within the R10P-R15P-R18P series. Typical applications include through-hole and blind-hole drilling in metal fabrication, mechanical assembly, and general maintenance work. The 11xD flute-to-diameter ratio provides good chip clearance across material types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter H size: 17\/64 inch (0.2660 inch decimal) diameter\u003c\/li\u003e\n  \u003cli\u003e118-degree standard drill point angle for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across metal workpieces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design reduces cutting thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute with 2-flute configuration\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish; ANSI-compliant; Series R10P-R15P-R18P\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber length drill bit compatible with standard drill chucks accepting a 17\/64 inch straight-cylindrical shank.
