It measures 1\/8 inch (0.1250 inch decimal) in diameter with a 135-degree split point that reduces walking on entry and lowers the thrust needed to start a hole. The parabolic flute geometry — at a 6xD flute-to-diameter ratio and 2-3\/4 inches of flute length — promotes efficient chip evacuation during deep drilling operations. The bit is manufactured from high-speed steel with a bright\/uncoated finish and is used by machinists, maintenance technicians, and metalworking professionals.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling into a broad range of workpiece materials in both production and repair environments. The straight shank fits standard drill chucks without adapters. The taper length body gives more reach than a jobber bit while keeping rigidity. It is well matched to drill press, hand drill, and CNC drilling applications where a 1\/8-inch diameter hole is required in metal, alloy, or composite stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust requirement\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design at 6xD ratio promotes fast chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles heat generated in heavy-duty drilling cycles\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup to affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eStraight, non-threaded shank fits standard drill chucks directly\u003c\/li\u003e\n  \u003cli\u003eANSI standard compliance for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, magnesium, magnesium alloy, malleable iron, nickel, stainless steel, steel, tempered steel, titanium, and titanium alloy workpieces.
