The PRECISION TWIST DRILL 5998922 is a jobber-length drill bit sized to Letter V (0.3770 inches decimal equivalent), designed for general-purpose drilling in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree standard point angle and a two-flute regular spiral configuration. The straight-cylindrical shank measures 0.3770 inches in diameter, and the overall length is 5 inches. It is intended for use by machinists, maintenance technicians, and fabricators working with ferrous and non-ferrous metals.
This drill bit is suited for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The web-thinned, tapered-web design reduces thrust at the point and supports cleaner hole entry. With a flute length of 3.625 inches, the bit accommodates drilling depths up to 3.625 inches, making it practical for through-hole and deep-hole work in both production and maintenance environments. It falls within the R10P-R15P-R18P series from Precision Twist Drill.
Designed as a general-purpose jobber-length drill bit compatible with standard drill chucks and drilling equipment accepting a 0.3770-inch straight-cylindrical shank. Part of the PRECISION TWIST DRILL R10P-R15P-R18P series.
Installation and use should be performed by qualified machinists or technicians familiar with drill press, CNC, or hand-drill operation. Secure the workpiece before drilling and ensure the chuck is properly tightened on the straight shank before operation. Coolant-through is not supported on this bit; apply external cutting fluid as needed when drilling hard materials such as stainless steel or superalloys. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.
