Cleveland C04383 Screw Machine Drill Bit Wire 50 Hss

Product Description

The CLEVELAND C04383 is a screw machine length (stub length) drill bit sized at wire gauge 50, equivalent to 0.0700 inches in diameter. Built from high-speed steel (HSS) with a bright uncoated finish, it features a 118-degree standard point angle and a two-flute spiral design with web thinning for improved chip clearance and reduced thrust on entry. The straight-cylindrical shank measures 0.0700 inches in diameter and 1 inch in shank length, with an overall length of 1-11/16 inches. This bit is designed for general-purpose drilling in tight clearance applications where a shorter flute length provides added rigidity and control.

The C04383 is suited for drilling into alloy steel and aluminum in production and maintenance environments. Its short overall length makes it a practical choice for drill press, CNC, and turret lathe applications where standard-length bits would chatter or deflect. Machinists and tool-and-die professionals commonly specify screw machine length bits for small-diameter, close-tolerance work. The right-hand cut configuration is compatible with standard spindle rotation.

Key Features

• Wire gauge 50 size at 0.0700 inches diameter with a tight tolerance of +0.0000 to -0.0005 inches
• High-speed steel construction for general-purpose performance across alloy and aluminum workpieces
• 118-degree standard point angle with web-thinned, parallel web configuration for reduced entry thrust
• Short screw machine length body at 1-11/16 inches OAL for rigidity in confined setups
• Two-flute spiral design with 11/16-inch flute length promotes chip evacuation in shallow-hole drilling
• Meets ASME B94.11M standards for dimensional accuracy and consistency

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks and collets accepting a 0.0700-inch straight-cylindrical shank. Fits equipment with right-hand spindle rotation. Part of Cleveland Series 2120.

Installation Notes

Installation and use should follow safe machine tool practices in accordance with applicable shop safety standards. Secure the shank fully in the chuck or collet before running the spindle, and confirm chuck key removal prior to operation. Use cutting fluid appropriate for the workpiece material when drilling alloy steel to extend tool life and maintain hole tolerance. Inspect the cutting edges for wear before use, particularly on small-diameter bits where lip damage is not always visible to the naked eye.
