Precision Twist Drill 5998202 Jobber Drill Bit Wire 10

Product Description

The PRECISION TWIST DRILL 5998202 is a jobber-length drill bit designed for general-purpose drilling in steel, cast iron, non-ferrous metals, and superalloys including titanium. It is manufactured from high-speed steel with a bright uncoated finish and features a standard 118-degree point angle with a web-thinned, tapered web for improved chip clearance. The straight-cylindrical shank measures 0.1935 inches in diameter, matching the drill diameter for use in standard chucks. With an overall length of 3.625 inches and a 2-flute spiral flute configuration, this bit delivers efficient material removal in production and maintenance drilling applications.

This drill bit is suited for use in machine shop environments, maintenance facilities, and fabrication settings where wire-size drilling is required. Wire size 10 corresponds to 0.1935 inches decimal equivalent. The right-hand cut and regular spiral flute design make it compatible with standard drill presses, CNC machining centers, and hand-held power drills. It is appropriate for residential, commercial, and industrial applications where close-tolerance hole sizing is needed. The R10H-R18H series designation covers a range of wire-size drill bits built to ANSI standards.

Key Features

Compatibility

Designed as an OEM-style jobber-length drill bit built to ANSI standards, suitable for use in standard drill chucks and collet systems accepting a 0.1935-inch straight shank. Compatible with steel, cast iron, non-ferrous metals, and superalloys including titanium as primary workpiece materials.

Installation Notes

Installation is performed by machinists, maintenance technicians, and metalworking tradespeople using standard drill presses or power drill equipment. Always secure the workpiece and ensure the chuck is properly tightened before drilling. Power down equipment and remove the bit from the chuck before inspecting or replacing. Follow applicable workplace safety standards when drilling into superalloys or cast iron, as these materials generate fine chips and elevated heat.
