Cleveland C04443 Screw Machine Drill Bit Wire 25 Hss

Product Description

The CLEVELAND C04443 is a screw machine length (stub length) twist drill bit designed for general-purpose drilling in metal fabrication, machining, and production environments. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit carries a wire gauge size of 25, corresponding to a decimal diameter of 0.1495 inches. The 118-degree standard point angle delivers reliable, self-centering starts on most common workpiece materials. At 2-1/16 inches overall length, the short body reduces deflection and improves rigidity in turret lathes, drill presses, and screw machines. It conforms to ASME B94.11M standards and is web-thinned for reduced thrust during entry.

The C04443 is suited for drilling alloy steel and aluminum in light to medium production runs. Its stub length profile makes it a go-to for CNC machining centers, turret lathes, and automatic screw machines where clearance is limited and rigidity is critical. General-purpose machinists, tool-and-die shops, and metalworking production lines are the primary users of this drill bit size and series.

Key Features

• Wire size 25 with a decimal diameter of 0.1495 inches for precise hole sizing
• High-speed steel construction provides durability across alloy and aluminum workpieces
• 118-degree standard point angle for reliable starts on ferrous and non-ferrous materials
• Screw machine (stub) length of 2-1/16 inches overall reduces deflection and chatter
• Web-thinned geometry lowers cutting thrust and extends tool life
• Bright uncoated finish compatible with cutting fluids and coolant-free dry drilling
• Conforms to ASME B94.11M for consistent dimensional tolerancing

Compatibility

Designed as an OEM-style general-purpose drill bit for use with standard straight-shank drill chucks in screw machines, turret lathes, drill presses, and CNC machining centers accepting 0.1495-inch shank tooling.

Installation Notes

Installation is performed by machinists and toolroom personnel in standard drill chuck or collet setups. Ensure the chuck or collet is clean and free of chips before seating the straight-cylindrical shank. Power down and de-energize the machine spindle completely before changing tooling. For optimal tool life, use an appropriate cutting fluid for the workpiece material and verify spindle RPM matches the recommended surface footage for HSS tooling at this diameter.
