Cleveland C03016 Jobber Length Drill Bit Wire Size 20

Product Description

The CLEVELAND C03016 is a jobber-length twist drill bit designed for general-purpose drilling in metal, aluminum, and similar materials. It is manufactured from high speed steel with a bright uncoated finish and features a standard 118-degree split point with web thinning for improved centering and reduced thrust on entry. The bit measures 3.25 inches overall length with a 2.125-inch flute length and runs a straight cylindrical shank at 0.1610 inches in diameter. The fast spiral flute geometry promotes efficient chip evacuation during through-hole drilling. This is a single-piece item sold individually.

This drill bit is intended for use in hand-held drills, drill presses, and milling machine setups where wire size No. 20 holes are required. At 0.1610 inches in decimal equivalence, it covers common fastener clearance and tapping pilot applications in aluminum, soft steel, plastics, and similar workpiece materials. The right-hand cut and two-flute configuration make it compatible with standard right-hand drill chucks across industrial and trade applications. It conforms to ASME B94.11M dimensional standards and carries an ANSI specification designation under Series 2012.

Installation Notes

This bit is installed by machinists, maintenance technicians, and trade professionals using standard drill chuck tooling. Secure the shank fully in the chuck jaws and verify runout before drilling. Use appropriate cutting fluid or lubrication when drilling steel to extend tool life. Follow shop safety protocols including eye protection and workpiece clamping before operation.
