Cleveland C04407 Screw Machine Drill Bit Wire 41 Hss

Product Description

The CLEVELAND C04407 is a screw machine length drill bit designed for high-speed steel cutting in general-purpose metal drilling applications. Built to wire gauge size 41, it measures 0.0960 inches in diameter with a 118-degree standard point angle and a bright, uncoated finish. The short flute design and parallel web configuration with web thinning reduce thrust and improve chip evacuation in tight drilling situations. This bit is suited for machinists, tool-and-die technicians, and production shop personnel who require consistent, repeatable hole quality in compact drill-press or screw-machine setups.

The C04407 is used in production machining environments where a stubby, rigid drill profile is preferred over jobber-length bits. Its reduced overall length of 1-13/16 inches minimizes deflection, making it well-suited for drilling alloy steels and aluminum in applications where chatter or bit wander is a concern. The straight cylindrical shank fits standard chucks without modification, and the right-hand spiral flutes match conventional drill-press and CNC spindle rotation.

Key Features

• Wire gauge size 41 (0.0960 inches) with tight diameter tolerance of +0.0000 to -0.0005 inches
• 118-degree standard point angle for general-purpose entry on steel and aluminum
• Web-thinned parallel web reduces cutting resistance and improves hole start accuracy
• Short screw machine length (1-13/16 inches OAL) provides rigidity and reduces deflection
• High-speed steel construction handles intermittent cutting loads without specialty coatings
• Meets ASME B94.11M standard for drill bit dimensional accuracy

Compatibility

Designed as a general-purpose screw machine length drill bit for use in standard three-jaw chucks, collet holders, and screw machine spindles accepting a 0.0960-inch straight cylindrical shank. Primary workpiece materials listed are alloy steel and aluminum.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with drill press, turret lathe, or CNC operation. Secure the straight shank firmly in a matching chuck or collet before operation to prevent runout. Always power down and lock out the machine spindle before changing bits. Do not exceed the recommended feed and speed range for the workpiece material, and inspect the cutting edges for wear before each use to avoid oversized holes or bit breakage.
