Precision Twist Drill 5999045 Jobber Drill Bit 38 Hss

Product Description

The PRECISION TWIST DRILL 5999045 is a jobber-length drill bit sized to wire gauge 38, with a decimal diameter of 0.1015 inches. Manufactured from high speed steel with a bright uncoated finish, it features a standard 118-degree split point and a regular spiral flute with web thinning for reduced thrust on entry. The straight-cylindrical shank measures 0.1015 inches in diameter and 1.0625 inches in length. Overall length is 2.5 inches, with a flute length of 1.4375 inches and a maximum drilling depth of 1.4375 inches. This bit is part of the R10P-R15P-R18P series and is built for general-purpose drilling in production and maintenance environments. Licensed HVAC technicians, machinists, and trade professionals install this bit using standard drill presses or hand-held drills.

This drill bit is suited for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The 14xD flute-to-diameter ratio supports efficient chip evacuation in deep-hole drilling applications. It is a practical choice for sheet metal work, mechanical assembly, and field service drilling where a small-diameter precision hole is required. The bit conforms to ANSI standards and carries no coolant-through capability, making it appropriate for dry or externally lubricated drilling setups. Each unit is packaged individually.

Installation Notes

This bit is installed and removed by a qualified tradesperson using a standard keyed or keyless chuck. Secure the workpiece before drilling to prevent movement and ensure hole accuracy. Apply cutting fluid or lubricant when drilling stainless steel, superalloys, or titanium to extend bit life and reduce heat buildup. Do not exceed the recommended drilling depth of 1.4375 inches for this bit diameter.
