Made from high speed steel with a steam oxide coating, it is built for general-purpose drilling in metal fabrication, maintenance, and light industrial applications. The bit features a 118-degree standard point angle, a right-hand spiral flute, and a straight cylindrical shank. Overall length is 2.375 inches, with a 1.375-inch flute length. Licensed HVAC technicians, plumbers, electricians, and general tradespeople commonly reach for jobber-length bits like this one when drilling pilot holes or clearance holes in steel and other metal workpieces.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard drill chucks that accept a 0.0995-inch straight cylindrical shank. With a 14xD flute-to-diameter ratio and a maximum drilling depth of 1.375 inches, it handles typical through-hole and blind-hole tasks in sheet metal, structural steel, and mechanical assemblies. The R18 series designation indicates it meets ANSI standards for jobber-length geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 39 size — 0.0995 inches decimal diameter\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and provides mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral, 2-flute design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces entry force in harder materials\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI specifications — Series R10-R15-R18\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 any standard drill chuck or drill press accepting a 0.0995-inch straight cylindrical shank.
