Cleveland C02978 Jobber Drill Bit Wire 37 Hss

Product Description

The CLEVELAND C02978 is a wire gauge size 37 jobber length drill bit manufactured from high speed steel with a bright uncoated finish. At 0.1040 inches in diameter and 2.5 inches overall length, this drill bit is built for general-purpose drilling in aluminum and similar non-ferrous metals. The standard 118-degree split point and fast spiral flute geometry promote clean entry and efficient chip evacuation. Web thinning reduces thrust requirements and improves centering. This bit is a go-to for machinists, maintenance technicians, and trade professionals who need a reliable wire gauge drill for small-diameter work.

The C02978 is suited for production and bench drilling operations where wire gauge precision is required. The straight cylindrical shank fits standard drill chucks without adapters. The 1.4375-inch flute length provides adequate chip clearance for the typical hole depths encountered in sheet metal, aluminum stock, and light fabrication work. This bit is sold individually and is appropriate for hand-held drill presses and benchtop drill press use alike.

Compatibility

Designed as a general-purpose replacement jobber length drill bit for use in standard drill presses and hand-held drills with chucks accepting a 0.1040-inch straight cylindrical shank. Primary workpiece material is aluminum; suitable for similar non-ferrous applications within the 0.1000 to 0.1500 inch diameter range.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck. Ensure the chuck is fully tightened and the workpiece is securely clamped before operation. Use appropriate cutting fluid or lubrication when drilling aluminum to extend bit life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
