Cleveland C02921 Jobber Length Drill Bit Wire 59 Hss

Product Description

The CLEVELAND C02921 is a jobber-length drill bit designed for precision drilling in metal fabrication, maintenance, and general mechanical work. Built from high speed steel (HSS) with a bright uncoated finish, this bit handles a wide range of materials while maintaining a sharp, consistent edge. It carries a wire gauge size of 59, which corresponds to a decimal diameter of 0.0410 inches. The 118-degree standard point angle and fast spiral flute geometry make it well-suited for cutting aluminum and other non-ferrous materials. Two flutes channel chips efficiently and help prevent clogging during through-hole drilling. A web-thinned, tapered web design reduces thrust requirements at the start of the cut. Licensed HVAC techs, plumbers, electricians, and general trade mechanics reach for this size when precise small-diameter holes are needed.

This bit fits standard jobber-length applications across residential and light commercial service work. The straight-cylindrical shank seats securely in keyed or keyless drill chucks. At 1.625 inches overall length with a flute length of 0.6875 inches, it is compact enough for use in confined spaces while providing adequate chip clearance for typical drilling depths. The Series 2012 designation places it within a general-purpose HSS line built to ASME B94.11M standards, making it a reliable option for sheet metal, aluminum extrusions, and soft steel in everyday trade applications.

Key Features

• Wire size 59 with 0.0410-inch decimal diameter for tight-tolerance hole work
• High speed steel construction with bright uncoated finish for general-purpose use
• 118-degree standard point angle suits aluminum and common non-ferrous materials
• Fast spiral, two-flute design promotes efficient chip evacuation
• Web-thinned tapered web reduces entry thrust and minimizes walking
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets ASME B94.11M dimensional standards for consistent fit and performance

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard keyed or keyless drill chucks accepting a 0.0410-inch straight-cylindrical shank. Primary workpiece material is aluminum; suitable for general-purpose drilling in soft metals and plastics.

Installation Notes

Install and use this bit only in a properly secured drill press, hand drill, or driver rated for small-diameter HSS bits. Ensure the chuck is fully tightened and the workpiece is clamped before beginning the cut. Use cutting fluid or light oil when drilling ferrous materials to extend bit life and improve hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed, as a damaged bit in small diameters can deflect or break under normal feed pressure.
