The bit features a standard 118-degree point angle, a regular spiral flute with web thinning, and a straight-cylindrical shank for use in standard drill chucks. At 4.25 inches overall length with a 2.9375-inch flute length, this is a general-purpose two-flute drill intended for right-hand cutting. It conforms to ANSI standards and is suited for machinists, maintenance technicians, and fabricators performing everyday drilling operations in a wide range of materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in general-purpose shop and field applications. The tapered web configuration and web-thinned point reduce thrust requirements and improve chip evacuation. It fits any drill press, mill, or handheld drill with a straight-shank chuck. It belongs to the R10P-R15P-R18P series and carries a flute-to-diameter ratio of 10xD, making it well suited for through-hole drilling at moderate depths.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter L size — 0.290 inches diameter, straight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web construction to reduce entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction, bright uncoated finish — suitable for re-sharpening\u003c\/li\u003e\n  \u003cli\u003eTwo regular spiral flutes for efficient chip removal during through-hole drilling\u003c\/li\u003e\n  \u003cli\u003eMaximum drilling depth of 2.9375 inches — supports full flute-length engagement\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant geometry; rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose jobber-length drill bit compatible with any standard straight-shank drill chuck accepting a 0.290-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit should be performed by a qualified machinist or trades professional familiar with drilling operations.
