Precision Twist Drill 5999106 Jobber Drill Bit No. 54

Product Description

The PRECISION TWIST DRILL 5999106 is a jobber-length twist drill bit sized at No. 54 wire gauge, equivalent to 0.0550 inches in diameter. Manufactured from high speed steel with a bright uncoated finish, this bit features a standard 118-degree split point and a regular spiral flute with web thinning for improved chip evacuation and reduced thrust. The straight-cylindrical shank measures 0.0550 inches in diameter and 1.000 inch in length. Overall length is 1.875 inches with a flute length of 0.875 inches. It is right-hand cut and designed for general-purpose drilling in a production or maintenance environment.

This drill bit is suited for drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The R18P series geometry and ANSI-standard tolerances make it appropriate for use in machining shops, maintenance and repair operations, and light manufacturing settings where small-diameter precision drilling is required. It is sold individually but requires a minimum order quantity of 12 units.

Installation Notes

Installation is performed by machinists, tool and die technicians, or maintenance professionals using a standard keyed or keyless drill chuck. Ensure the chuck is fully tightened and the workpiece is securely fixtured before drilling. For small-diameter bits such as this, use appropriate feed rates and speeds for the workpiece material to avoid bit deflection or breakage. Do not apply excessive lateral force during drilling.
