Cleveland C04480 Screw Machine Drill Bit Wire 7 Hss

Product Description

The CLEVELAND C04480 is a screw machine length drill bit designed for general-purpose drilling in metal fabrication, machining, and assembly applications. It is manufactured from high-speed steel with a bright, uncoated finish and features a standard 118-degree split point with web thinning for improved centering and reduced thrust. The bit measures 2.25 inches overall length with a straight cylindrical shank and cuts in a right-hand direction. Its shorter-than-jobber body makes it well suited for use in turret lathes, screw machines, and drill presses where rigidity and stub-length clearance are required.

The C04480 is sized to wire gauge No. 7, equivalent to 0.2010 inches decimal diameter, and falls within the Series 2120 product family. It is appropriate for drilling alloy steel and aluminum in both production and maintenance environments. The short flute length and parallel web configuration contribute to stability in repetitive drilling cycles, making this bit a practical choice for machine shops and production lines running moderate-volume operations on ferrous and non-ferrous workpieces.

Key Features

• Wire size No. 7 — 0.2010 inch decimal diameter with a tight tolerance of +0.0000 to -0.0007 inches
• High-speed steel construction suitable for alloy steel and aluminum workpieces
• 118-degree standard point angle with web thinning for reduced entry thrust
• Screw machine (stub) length at 2.25 inches OAL for increased rigidity in machine tool setups
• Bright uncoated finish — no coating to interfere with regrinding
• Conforms to ASME B94.11M standard

Compatibility

Designed as an OEM-style replacement and standard replacement drill bit for screw machines, turret lathes, CNC drill presses, and general machining equipment that accept straight cylindrical shank tooling in the 0.2010 inch diameter range.

Installation Notes

Installation of this bit is performed by machinists or toolroom technicians. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the straight cylindrical shank fully and securely in the drill chuck or collet before operation. Verify spindle speed is appropriate for the workpiece material and bit diameter per standard machining reference data before beginning a drilling cycle.
