Cleveland C04448 5/32 Inch Hss Screw Machine Drill Bit

Product Description

The CLEVELAND C04448 is a screw machine length (stub length) drill bit designed for high-volume, close-tolerance drilling in production and maintenance environments. Built from high-speed steel (HSS) with a bright/uncoated finish, it measures 5/32 inches (0.1562 inches decimal) in diameter and carries a 118-degree standard point angle with web thinning for improved penetration and reduced thrust. The two-flute, right-hand spiral design provides efficient chip evacuation. With an overall length of 2-1/16 inches and a flute length of 1 inch, this stub-length geometry offers greater rigidity than jobber-length bits, reducing deflection in drill press and CNC applications.

The C04448 is suited for general-purpose drilling in alloy steel, aluminum, and similar workpiece materials. Its short overall length makes it a practical choice for confined spaces and production drilling where runout control and bit stiffness matter. The straight-cylindrical shank seats cleanly in standard drill chucks, collets, and quick-change adapters. This bit is commonly used by machinists, pipefitters, HVAC fabricators, and maintenance technicians working on sheet metal, light structural steel, and aluminum assemblies.

Key Features

• High-speed steel construction for general-purpose metal drilling
• 118-degree standard point angle with web thinning for reduced entry thrust
• Screw machine (stub) length at 2-1/16 inches OAL for added rigidity and reduced deflection
• Right-hand, two-flute regular spiral geometry for efficient chip clearance
• Bright/uncoated finish compatible with cutting fluids and oils
• Meets ASME B94.11M standards with diameter tolerance of +0.0000 to -0.0007 inches

Compatibility

Designed as a general-purpose stub-length drill bit for use in standard drill chucks, collets, and quick-change tooling systems accepting a 0.1563-inch straight-cylindrical shank. Suitable for alloy steel and aluminum workpieces per Cleveland Series 2120 specifications.

Installation Notes

Installation and use should follow safe machine tool practices: secure the shank fully in the chuck or collet before operation and verify runout before drilling production parts. Power down and lock out the machine before changing bits. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole-diameter tolerance. Inspect the point and cutting edges before each use and replace the bit if chipping or wear is observed.
