Cleveland C02918 Jobber Drill Bit Wire 61 Hss

Product Description

The CLEVELAND C02918 is a jobber-length drill bit in wire gauge size 61, with a decimal diameter of 0.0390 inches. Made from high speed steel with a bright uncoated finish, it features a standard 118-degree split-point tip and a fast spiral flute design with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank measures 0.0390 inches in diameter. With an overall length of 1.625 inches and a flute length of 0.6875 inches, this bit is sized for precise small-hole drilling in metalworking and light fabrication environments. It is typically installed by machinists, maintenance technicians, and tool and die professionals.

The C02918 is well suited for drilling aluminum and similar non-ferrous materials in production and repair settings. The fast spiral geometry promotes chip evacuation in softer materials, helping maintain hole quality and bit life. The 2-flute configuration and web-thinned tip reduce cutting force, making it a practical choice for close-tolerance work where small wire-gauge holes are required. This bit ships in single-piece quantity and is sold in minimum order multiples of 10 units.

Key Features

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard drill chucks and collets accepting a 0.0390-inch straight-cylindrical shank. Primary workpiece material is aluminum; suitable for general-purpose small-hole drilling applications within the 0.0000 to 0.0500 inch decimal size range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press, CNC, or hand-drill operation at appropriate speeds for high speed steel tooling in the target material. Secure the shank fully in the chuck or collet before operation and confirm runout is within acceptable limits for the application. Do not exceed recommended surface footage for HSS tooling in the chosen workpiece material, as overheating will degrade the cutting edge and shorten tool life.
