Cleveland C04449 Screw Machine Drill Bit Wire 22 Hss

Product Description

The CLEVELAND C04449 is a screw machine length (stub length) drill bit sized to wire gauge No. 22, equivalent to 0.1570 inches in diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, it is designed for general-purpose drilling in production and maintenance environments. The 118-degree standard point angle provides a self-centering start on most common materials. With an overall length of 2.125 inches and a 1.0625-inch flute length, the short body reduces deflection and increases rigidity compared to jobber-length bits, making it well suited for screw machine and drill press applications.

This bit is used in metal fabrication, machine shops, and general maintenance settings where short, rigid tooling is preferred. It is appropriate for drilling into alloy steel and aluminum. The straight cylindrical shank at 0.1570 inches in diameter seats securely in standard drill chucks and quick-change holders. Its general-purpose grade and ASME B94.11M compliance make it a reliable choice for both CNC screw machine operations and manual drill press work in light industrial and trade environments.

Key Features

• Wire size No. 22 (0.1570 inches) for precise hole sizing in production drilling
• High-speed steel construction for durability across alloy steel and aluminum workpieces
• 118-degree standard point angle with web-thinned tip for reduced thrust and easier starting
• Screw machine (stub) length at 2.125 inches overall reduces deflection in short-reach applications
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Meets ASME B94.11M standards for dimensional accuracy with a diameter tolerance of +0.0000 to -0.0007 inches

Compatibility

Designed as a general-purpose replacement or production bit for applications requiring a wire gauge No. 22 hole in alloy steel or aluminum. Fits standard drill chucks and quick-change tooling systems accepting a 0.1570-inch straight cylindrical shank.

Installation Notes

This bit is installed and operated by machinists, tool and die technicians, and maintenance professionals using drill presses, screw machines, or CNC drilling equipment. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Use appropriate cutting fluid when drilling alloy steel to extend tool life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
