Cleveland C02924 Jobber Drill Bit Wire 57 Hss

Product Description

The CLEVELAND C02924 is a jobber-length drill bit sized to wire gauge 57 (0.0430 inches decimal) and manufactured from high speed steel with a bright uncoated finish. The bit features a 118-degree standard point angle, a fast spiral flute configuration, and a web-thinned tapered web design that reduces thrust at entry and improves chip evacuation. Overall length is 1.75 inches with a 0.75-inch flute length and a straight-cylindrical shank. This is a general-purpose drill bit suited for machinists, maintenance technicians, and trade professionals who work with small-diameter precision holes in production or field applications.

The C02924 is rated for aluminum as its primary workpiece material and is appropriate for use in hand drills, drill presses, and CNC drilling operations where small wire-gauge sizes are required. The right-hand cutting direction and straight shank make it compatible with standard three-jaw chucks. No coolant-through capability is present, so conventional flood or mist cooling applies when drilling at higher feed rates or in thermally sensitive materials. This bit conforms to ASME B94.11M and is sold individually with a minimum order quantity of 10 units.

Key Features

• Wire gauge size 57 at 0.0430 inches decimal diameter
• 118-degree standard point angle with web-thinned tapered web for reduced entry thrust
• Fast spiral flute geometry promotes efficient chip removal
• High speed steel construction with bright uncoated finish
• Right-hand cut, straight-cylindrical shank fits standard chucks
• Conforms to ASME B94.11M and ANSI specification designation

Compatibility

Designed as a general-purpose OEM-style jobber drill bit for use in standard three-jaw chucks and collet systems that accept a 0.0430-inch straight shank, consistent with ASME B94.11M Series 2012 jobber-length geometry.

Installation Notes

This bit should be installed and operated by qualified machinists or trade technicians familiar with small-diameter tooling. Secure the shank fully in a properly sized chuck before operation to prevent runout or bit breakage. At this diameter, excessive feed pressure is the leading cause of bit failure — allow the cutting geometry to do the work. Inspect the point for wear or chipping before each use, as small wire-gauge bits are not practical to resharpen in the field.
