Cleveland C01034 Jobber Drill Bit Wire 70 0.0280 in Hss

Product Description

The CLEVELAND C01034 is a wire gauge size 70 jobber length drill bit designed for general-purpose drilling in metal fabrication and maintenance applications. Manufactured from high speed steel with an oxide coating, it measures 0.028 inches in diameter and 1.25 inches in overall length. The standard 118-degree split-point geometry with web thinning reduces walking and improves penetration in ferrous materials. Two spiral flutes with a regular helix clear chips efficiently during through-hole drilling. This bit is suited for use by machinists, HVAC installers, plumbers, and electricians who require small-diameter precision holes in sheet metal, cast iron, or steel.

The C01034 is a general-purpose jobber length bit appropriate for benchtop drill presses, hand drills, and small CNC setups. Its straight-cylindrical shank seats in standard three-jaw chucks without adapter hardware. The 0.375-inch flute length accommodates typical sheet metal and light structural stock thicknesses. Primary workpiece materials include cast iron and steel, making it a practical choice for drilling pilot holes, fastener clearance holes, and instrument port openings in trade service work.

Key Features

• Wire gauge size 70, 0.0280-inch diameter with a tight tolerance of -0.0005 to 0.0000 inches
• High speed steel construction with oxide coating for corrosion resistance and reduced friction
• 118-degree standard point angle with web thinning for reduced entry force
• Two spiral flutes, regular helix, for efficient chip evacuation in ferrous materials
• Straight-cylindrical shank fits standard three-jaw drill chucks without adapters
• Meets ASME B94.11M and DIN 338 standards

Compatibility

Designed as a general-purpose OEM-style jobber length drill bit suitable for standard three-jaw chuck drill presses and hand drills accepting straight-cylindrical shanks in the 0.028-inch diameter range.

Installation Notes

This bit is installed and used by machinists, pipefitters, electricians, and HVAC technicians performing metal drilling tasks. Always secure the workpiece firmly before drilling and use appropriate cutting fluid or lubricant when drilling cast iron or hardened steel to extend bit life. Disconnect power to any equipment before drilling into panels or assemblies. Do not exceed the recommended RPM range for the bit diameter as specified by the drill press or hand tool manufacturer.
