Cleveland C04411 Screw Machine Drill Bit Wire 39 Hss

Product Description

The CLEVELAND C04411 is a screw machine length (stub) drill bit sized to wire gauge number 39, with a decimal diameter of 0.0995 inches. Built from high-speed steel with a bright, uncoated finish, it features a standard 118-degree split point and a two-flute spiral design. The short flute length and reduced overall length of 1-13/16 inches make it well suited for applications where rigidity and reduced deflection matter. The web-thinned, parallel-web construction lowers thrust during entry, and the straight-cylindrical shank seats cleanly in standard drill chucks. This bit carries ASME B94.11M compliance for dimensional accuracy.

The C04411 is used in general-purpose drilling operations in machine shops, production environments, and field trade work. It is designed for drilling alloy steel and aluminum, making it a common choice for HVAC, electrical, and mechanical trades when precise, small-diameter holes are required in metal. The screw machine length is preferred in CNC drilling, drill press work, and turret lathe operations where stub-length bits reduce chatter and improve hole accuracy in short-run or production drilling.

Key Features

• Wire gauge size 39, decimal diameter 0.0995 inches for precise small-hole drilling
• High-speed steel construction for general-purpose metal cutting
• 118-degree standard point angle with web-thinned tip to reduce entry thrust
• Screw machine (stub) length at 1-13/16 inches OAL for increased rigidity
• Right-hand cut with regular spiral and straight-cylindrical shank
• Diameter tolerance held to +0.0000 to -0.0005 inches per ASME B94.11M

Compatibility

Designed as a general-purpose screw machine length drill bit for use in standard drill chucks, CNC spindles, and turret lathes accepting a 0.0995-inch straight-cylindrical shank. Suitable for drilling alloy steel and aluminum workpieces.

Installation Notes

Installation and use should be performed by machinists or qualified trade professionals familiar with metal-cutting operations. Secure the shank fully in the chuck or collet before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Inspect the cutting edges for wear or damage before each use. Follow applicable shop safety practices and equipment manufacturer guidelines when operating drilling machinery.
