Built from high speed steel (HSS) with a bright, uncoated finish, it features a 118-degree standard drill point and a right-hand spiral flute for efficient chip evacuation. The flute length measures 4 inches, and the overall length is 6-3\/8 inches, giving it additional reach compared to a jobber-length bit. It carries a straight shank with a 0.3125 inch diameter, fits standard drill chucks, and belongs to Precision Twist Drill Series R51. Licensed HVAC techs, plumbers, electricians, and mechanical contractors use this bit for structural and equipment-installation drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling in both shop and field environments where extended reach into workpieces is needed. It is commonly used in light fabrication, equipment mounting, and trade installation work. The 6xD flute-to-diameter ratio and tapered web configuration make it effective in materials including alloy steel, aluminum, brass, bronze, carbon steel, cast iron, copper, stainless steel, nickel alloys, magnesium alloys, malleable iron, graphite, reinforced plastics, and high-strength bronze. It conforms to ANSI standards and is classified as a general-purpose grade tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch (0.3125 inches) diameter with straight shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose material entry\u003c\/li\u003e\n  \u003cli\u003e4 inch spiral flute length provides extended reach versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with bright, uncoated finish\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web configuration reduces thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, ANSI-compliant, Series R51 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose taper length drill bit compatible with any standard drill chuck accepting a 0.3125 inch straight shank.
