Precision Twist Drill 5999181 Jobber Drill Bit Wire 50

Product Description

The PRECISION TWIST DRILL 5999181 is a jobber-length twist drill bit designed for general-purpose drilling in metal and hard materials. It carries a wire gauge size of 50, which corresponds to a decimal diameter of 0.0700 inches. The bit is machined from high speed steel and finished with a steam oxide coating that reduces friction and helps resist corrosion during use. Overall length is 2 inches, with a 1-inch spiral flute and a standard 118-degree split point. The straight-cylindrical shank and right-hand cut make it compatible with standard drill chucks found on most bench and handheld drilling equipment. Installed by machinists, maintenance technicians, and trade professionals who need repeatable, accurate small-diameter holes.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It falls within the R10A-R15A-R18A series and conforms to ANSI and NAS 907 specifications, making it appropriate for applications where dimensional and performance standards are required. The regular spiral type and tapered web configuration are well-matched to production drilling and maintenance drilling tasks at this diameter range. It is sold individually and is a direct replacement or supplemental bit for shop and field inventory.

Installation Notes

This drill bit is installed and used by machinists, maintenance technicians, and trade professionals working with standard drilling equipment. Always power down and secure the workpiece before changing or seating the bit in the chuck. Verify chuck capacity accommodates the 0.0700-inch shank diameter before use. Do not exceed the rated maximum drilling depth of 1 inch in a single pass without clearing chips from the flute.
