Cleveland C03042 Jobber Drill Bit Wire 8 0.1990 in Hss

Product Description

The CLEVELAND C03042 is a jobber-length twist drill bit designed for general-purpose hole-making in metal, wood, and plastic. Built from high speed steel with a bright finish, it carries a 118-degree standard point angle and a fast spiral flute geometry that clears chips efficiently during drilling. The straight-cylindrical shank seats securely in standard drill chucks without slipping. With an overall length of 3.625 inches and a flute length of 2.4375 inches, this bit handles typical jobber-depth applications in production and maintenance work. The web-thinned, tapered web reduces entry force and improves centering on the workpiece.

This bit is sized to wire gauge number 8, with a decimal diameter of 0.1990 inches and a shank diameter of 0.1990 inches, placing it in the 0.1500 to 0.2000 inch drill size range. It is suited for use in drill presses, hand drills, and CNC drilling operations where a general-purpose HSS bit is appropriate. Common applications include pilot hole drilling, through-hole work in light steel and aluminum, and fixture fabrication in machine shops, fabrication facilities, and maintenance environments. Right-hand cutting direction is standard for use with conventional drill equipment.

Key Features

• High speed steel construction provides durability across a wide range of workpiece materials
• 118-degree standard point angle suits general-purpose drilling in metal and non-ferrous materials
• Bright finish with no coating for straightforward resharpening and inspection
• Fast spiral flute promotes efficient chip evacuation during drilling
• Web-thinned tapered web reduces thrust force and improves hole entry
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks and collet systems accepting a 0.1990-inch straight shank. Conforms to ANSI specification designation for jobber-length drill bits.

Installation Notes

Installation and use should follow standard machine shop safety practices. Secure the shank fully in the chuck before operation and verify chuck key removal before powering the drill. Use appropriate cutting fluid or lubrication when drilling ferrous metals to extend cutting edge life. Inspect the cutting edges before each use and resharpen or replace the bit when point geometry shows wear.
