Cleveland C03019 Jobber Drill Bit No.19 Hss 0.1660 in

Product Description

The CLEVELAND C03019 is a jobber-length drill bit in wire gauge size No. 19 (0.1660 inches decimal), manufactured from high speed steel with a bright finish. It features a standard 118-degree split point with web thinning for improved penetration and reduced walking on entry. The fast spiral flute design promotes efficient chip evacuation during drilling operations. With an overall length of 3.25 inches and a flute length of 2.125 inches, this bit fits standard three-jaw drill chucks via its straight-cylindrical shank. It is suited for general-purpose drilling by machinists, pipefitters, electricians, and HVAC technicians working with ferrous and non-ferrous metals.

This drill bit is intended for general-purpose metalworking applications where precise wire gauge sizing is required. Wire size No. 19 at 0.1660 inches is commonly used for pilot holes, tapping preparation, and through-hole work in light-gauge steel, aluminum, copper tubing, and similar materials. It conforms to ANSI specifications, making it a reliable choice for shop, field, and service van use across the mechanical trades. The bright coating keeps manufacturing costs low while still delivering adequate performance in non-abrasive materials.

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard three-jaw drill chucks accepting a 0.1660-inch straight-cylindrical shank, compatible with benchtop drill presses, handheld power drills, and magnetic base drills used across the mechanical trades.

Installation Notes

Installation is performed by machinists, pipefitters, electricians, and HVAC service technicians using standard drill chucks. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid when drilling ferrous metals to extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
