Product Description

The PRECISION TWIST DRILL 5998340 is a jobber-length drill bit designed for general-purpose drilling in a wide range of materials. It measures 7/64 inch (0.1094 inch decimal) in diameter with an overall length of 2.625 inches and a flute length of 1.5 inches. Manufactured from high speed steel with a bright uncoated finish, it features a 118-degree standard point angle and a tapered web configuration with web thinning for improved chip clearance. The straight-cylindrical shank seats securely in standard drill chucks. This bit is suited for use by machinists, maintenance technicians, HVAC installers, plumbers, and electricians who need a reliable general-purpose bit for everyday drilling tasks.

The 5998340 is rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. Its 2-flute right-hand spiral design with regular spiral type handles chip evacuation efficiently across these workpiece categories. Maximum drilling depth reaches 1.5 inches, making it appropriate for through-hole and moderate-depth drilling applications in both shop and field settings. The shank diameter matches the drill diameter at 0.1094 inch, fitting standard 3-jaw chucks without adapters.
