It features a 135-degree split point and a parabolic spiral flute design with web thinning, which reduces walking on entry and lowers the thrust force needed to start a hole. Overall length is 3.625 inches with a flute length of 2.4375 inches. The straight cylindrical shank measures 0.1990 inches in diameter. This bit is a general-purpose, heavy-duty grade tool suited for production drilling and maintenance work performed by machinists and skilled tradespeople.\u003c\/p\u003e\n\u003cp\u003eThe 5997035 is designed for drilling into a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its 12xD flute-to-diameter ratio and tapered web configuration make it effective in both handheld drill and drill press applications. The Series QC21P designation places it in a line built to ANSI standards for consistent geometry across the production run. It is equally at home on a shop floor, a fabrication bench, or a field service application where a reliable wire-gauge bit is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 8 wire size — 0.1990 inches decimal equivalent for precise gauge-matched hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces walking and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eParabolic spiral flute with tapered web improves chip evacuation in deeper holes\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard drill chucks — no flat or drive notch\u003c\/li\u003e\n  \u003cli\u003eBuilt to ANSI standards under Series QC21P for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit for use in any standard drill chuck accepting a 0.1990-inch straight cylindrical shank, including benchtop drill presses, CNC drilling stations, and handheld power drills used in metal fabrication and maintenance trades.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized drill chuck and tighten with a chuck key before operation. Ensure the workpiece is securely clamped before drilling to prevent rotation or movement. For steel and stainless steel applications, use an appropriate cutting fluid to extend tool life and improve hole finish.
