Cleveland C04404 Screw Machine Drill Bit Wire 42 Hss

Product Description

The CLEVELAND C04404 is a screw machine length (stub length) drill bit designed for high-volume drilling applications where rigidity and accuracy matter. Built from high-speed steel with a bright uncoated finish, this bit carries a wire gauge size of 42, which corresponds to a decimal diameter of 0.0935 inches. The 118-degree standard point angle and web-thinned tip reduce thrust force at entry, improving hole quality in both alloy and aluminum workpieces. At 1.75 inches overall length with a 0.75-inch flute length, the short profile minimizes deflection in screw machine, turret lathe, and CNC drilling operations. HVAC, plumbing, and electrical tradespeople use bits in this size range for pilot holes, sheet metal work, and electrical panel knockouts.

The C04404 is suited for general-purpose production drilling in soft to medium-hardness metals including aluminum, alloys, and similar non-ferrous materials. Its compact screw machine length profile makes it a direct fit for automatic screw machines, drill presses, and handheld power tools where a shorter bit reduces chatter and walkoff. The straight cylindrical shank diameter of 0.0935 inches seats directly into standard drill chucks without adapters. Typical users include machinists, HVAC fabricators, and electrical contractors who drill sheet metal, tube stock, and structural components in repetitive production runs.

Key Features

• Wire size 42 with 0.0935-inch decimal diameter and tight tolerance of +0.0000 to -0.0005 inches
• High-speed steel construction for general-purpose metal drilling without coating degradation concerns
• 118-degree standard point angle with web-thinned tip to reduce entry thrust and improve hole accuracy
• Screw machine (stub) length at 1.75 inches overall minimizes deflection in tight setups
• Right-hand cut with two-flute spiral configuration for efficient chip evacuation
• Meets ASME B94.11M dimensional standards for interchangeability and quality consistency

Compatibility

Designed as a general-purpose replacement or production-stock drill bit compatible with standard drill chucks accepting a 0.0935-inch straight cylindrical shank. Suitable for use in automatic screw machines, CNC lathes, drill presses, and handheld power tools. Intended for drilling alloy and aluminum workpieces per Series 2120 application guidelines.

Installation Notes

Secure the straight cylindrical shank fully in the drill chuck before operation and verify runout before beginning a production run. Power down all equipment before changing bits. When drilling metals, use appropriate cutting fluid or coolant as needed to extend tool life, noting this bit does not support through-coolant delivery. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
