Built from high speed steel with a bright, uncoated finish, this bit delivers reliable cutting performance in demanding shop and field environments. The 0.098-inch diameter corresponds to a No. 40 wire gauge size. It features a 118-degree standard point angle, a right-hand spiral flute, and a straight cylindrical shank. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation, making it well suited for precision drilling in production and trade applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC drilling setups, and benchtop drill press applications where shorter overall length provides added rigidity and accuracy. The screw machine length format — shorter than jobber length — reduces deflection in close-tolerance work. With a flute-to-diameter ratio of 2.5xD and a flute length of 13\/16 inches, this bit handles materials such as titanium, steel, and aluminum in both production and maintenance repair environments. It is typically used by machinists, tool and die technicians, and industrial maintenance trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 40 wire gauge size at 0.098 inches diameter for close-tolerance drilling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for high-performance general-purpose drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tapered web for reduced thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine length format provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; Series R41 designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit drill bit for use in standard straight-shank drill chucks compatible with No. 40 wire gauge screw machine length tooling per ANSI specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and tooling technicians.
