Precision Twist Drill 5999298 Jobber Drill Bit Wire 16

Product Description

The PRECISION TWIST DRILL 5999298 is a jobber length drill bit in wire gauge size 16, measuring 0.1770 inches in diameter. It is manufactured from high speed steel with a steam oxide coating that reduces friction and helps resist corrosion during use. The bit features a 118-degree standard point angle, a regular spiral flute, and a straight-cylindrical shank. With an overall length of 3.375 inches and a flute length of 2.1875 inches, this bit is suited for general-purpose drilling in metal fabrication and maintenance applications. It is installed by machinists, maintenance technicians, and trade professionals working with ferrous and non-ferrous materials.

This bit is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It follows the NAS 907 specification and meets ANSI standards, making it appropriate for both shop and field use. The right-hand cutting direction and two-flute spiral configuration provide efficient chip evacuation during through-hole and blind-hole drilling operations. A web-thinned, tapered web design reduces thrust requirements at the point. This bit is part of the R10A, R15A, and R18A series.

Compatibility

Designed as a general-purpose jobber length drill bit for use with standard drill chucks and drilling equipment in applications requiring a wire gauge size 16 diameter. Part of the R10A, R15A, and R18A series. Suitable for workpiece materials coded P, M, K, N, and S per standard material classification.

Installation Notes

Installation and use is performed by machinists, maintenance technicians, and qualified trade professionals. Secure the straight-cylindrical shank firmly in the drill chuck before use and verify chuck tightness before operation. Do not exceed the recommended maximum drilling depth of 2.1875 inches for this bit length. Follow applicable shop safety procedures, including proper workpiece clamping and use of appropriate cutting fluid when drilling hard materials.
