Cleveland C01049 Jobber Length Drill Bit Wire 61 Hss

Product Description

The CLEVELAND C01049 is a jobber-length twist drill bit designed for general-purpose drilling in metalworking applications. Built from high speed steel with an oxide coating, this bit handles cast iron and steel with consistent results across production and maintenance work. It carries a wire gauge size of 61, equal to 0.0390 inches in decimal, with a standard 118-degree split point and a two-flute right-hand spiral configuration. Web thinning reduces entry resistance and helps keep the point centered at the start of the cut. The straight-cylindrical shank seats securely in standard drill chucks without adapters.

This bit suits light-duty drilling tasks on steel plate, castings, and ferrous assemblies in shop, field, and production line environments. The 11/16-inch flute length accommodates shallow-to-moderate hole depths typical of small-diameter wire-gauge work. The regular spiral flute evacuates chips efficiently at the small diameters where packing is a common failure mode. It meets ASME B94.11M and DIN 338 standards, making it appropriate for applications where dimensional conformance to published jobber-length specifications is required.

Key Features

• Wire gauge size 61 (0.0390 inches decimal) with diameter tolerance of -0.0005 to 0.0000 inches
• High speed steel construction with oxide finish for improved wear resistance on ferrous materials
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust at entry
• Right-hand cut, two-flute regular spiral for efficient chip evacuation in cast iron and steel
• Straight-cylindrical shank compatible with standard keyless and keyed drill chucks
• Meets ASME B94.11M and DIN 338 jobber-length standards

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.0390-inch straight-cylindrical shank. Rated for drilling cast iron and steel as primary workpiece materials.

Installation Notes

This bit is installed and serviced by machinists, maintenance mechanics, and metalworking tradespeople using standard drill presses, hand drills, or CNC drilling equipment. Secure the shank fully in the chuck before operation and confirm chuck key removal prior to spindle start. Use appropriate cutting fluid or lubricant when drilling steel to extend bit life and improve hole finish. Inspect the cutting edges before each use — at this diameter, edge damage is difficult to see but directly affects hole tolerance.
