Cleveland C02890 Jobber Length Drill Bit Wire 77 Hss

Product Description

The CLEVELAND C02890 is a wire gauge size 77 jobber length drill bit engineered for precision drilling in small-diameter applications. Manufactured from high speed steel with a bright uncoated finish, this bit measures 0.0180 inches in diameter and carries an overall length of 0.875 inches with a flute length of 0.1875 inches. The 118-degree standard point angle and fast spiral flute design promote efficient chip evacuation and accurate entry. A web-thinned, tapered web construction reduces thrust during penetration. Licensed HVAC technicians, plumbers, electricians, and sheet metal tradespeople reach for this bit when precise small-hole work is required on the job.

This bit is rated for general-purpose use with aluminum as the primary workpiece material, making it well suited for light-gauge sheet metal, aluminum extrusions, and similar non-ferrous stock encountered in residential and light commercial trade applications. The straight-cylindrical shank at 0.0180 inches diameter fits standard drill chucks and compatible collet holders without modification. It conforms to ASME B94.11M and ANSI specification designation standards, ensuring dimensional consistency across the Series 2012 product line.

Key Features

Compatibility

Designed as a general-purpose jobber length drill bit suitable for use with standard drill chucks and collet holders accepting a 0.0180-inch straight-cylindrical shank, intended primarily for aluminum and comparable non-ferrous workpiece materials.

Installation Notes

This bit is installed and operated by any trade professional using a handheld drill, drill press, or compatible rotary tool. Secure the straight-cylindrical shank firmly in the chuck before operation and confirm the workpiece is clamped or restrained. Use appropriate cutting fluid or lubrication when drilling non-ferrous metals to extend bit life and maintain hole quality. Follow applicable workplace safety standards and manufacturer equipment guidelines when operating rotary cutting tools.
