Cleveland C01808 Jobber Drill Bit Wire 77 0.0180 in Hss

Product Description

The CLEVELAND C01808 is a jobber-length drill bit in wire gauge size 77, with a decimal diameter of 0.0180 inches. It is manufactured from high speed steel with an oxide coating for wear resistance. The bit features a 118-degree standard point angle, a two-flute regular spiral configuration, and a straight-cylindrical shank of equal diameter to the cutting edge at 0.0180 inches. The web is thinned with a tapered web configuration to reduce thrust during entry. This is a general-purpose drill bit suited for light-duty precision hole-making operations and is typically handled by machinists, maintenance technicians, and production drilling professionals.

This bit is intended for use on aluminum as its primary workpiece material, though its general-purpose grade makes it applicable across a range of soft to medium materials in production and maintenance environments. With an overall length of 0.8750 inches and a flute length of 0.1880 inches, the C01808 is sized for tight-clearance work, small-diameter pilot holes, and applications where control and accuracy in small-gauge drilling are critical. It conforms to ASME B94.11M and DIN 338 standards. Sold individually; minimum order quantity is 10 units.

Key Features

• Wire gauge size 77 with a decimal diameter of 0.0180 inches for precision small-bore work
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction with oxide coating for surface hardness and lubricity
• Regular spiral, two-flute design promotes chip evacuation during drilling
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets ASME B94.11M and DIN 338 dimensional and performance standards

Compatibility

Designed as a general-purpose jobber-length drill bit for use with standard drill chucks accepting straight-cylindrical shanks. Rated for aluminum as the primary workpiece material; suitable for general-purpose applications in soft to medium materials per Series 2001 specifications.

Installation Notes

Install in a standard drill chuck and tighten securely before operation. Power down or de-energize the drilling machine completely before changing bits. At this diameter, use appropriate low-speed, high-feed settings and cutting fluid to prevent bit deflection or breakage. Dispose of worn bits per shop safety protocols and inspect the cutting edges before each use.
