Cleveland C04535 Screw Machine Drill Bit 19/64 in Hss

Product Description

The CLEVELAND C04535 is a screw machine length drill bit designed for high-speed steel drilling in general-purpose metalworking applications. It measures 19/64 inches (0.2969 inches) in diameter with a 118-degree standard point angle and a right-hand cutting direction. The overall length is 2-3/4 inches, making it shorter than jobber-length bits and well suited for use in turret lathes, screw machines, and drill presses where reduced overhang improves rigidity and accuracy. The bright, uncoated finish is typical for general-purpose HSS tooling used across a wide range of shop environments.

This bit is used in production machining and general fabrication work on alloy steel, aluminum, and similar materials. The short flute length and stubby overall length reduce deflection during drilling, which is particularly valuable in CNC lathes, screw machines, and multi-spindle setups. Installers and machinists in metal fabrication, HVAC equipment manufacturing, plumbing component production, and related trades will find this bit a standard workhorse for repetitive hole-making tasks at this diameter range.

Key Features

• 19/64 inch (0.2969 inch) diameter with tight tolerance of +0.0000 to -0.0010 inches for accurate hole sizing
• 118-degree standard point angle with web-thinned geometry for reduced thrust and improved centering
• High-speed steel construction provides durability across alloy steel and aluminum workpieces
• Screw machine (short) length at 2-3/4 inches OAL reduces deflection and improves rigidity in confined setups
• Right-hand cut with 2-flute regular spiral for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Meets ASME B94.11M standard for consistent dimensional accuracy

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard 3-jaw chucks, collets, and drill press spindles accepting straight-cylindrical shanks at 0.2969 inch diameter. Intended for use on alloy steel and aluminum workpieces per Series 2120 application guidelines.

Installation Notes

This drill bit is installed by qualified machinists and tool-room technicians using standard chuck or collet toolholding systems. Ensure the machine spindle is fully stopped and locked before changing or seating the bit. Verify chuck or collet runout is within acceptable limits to preserve the tight diameter tolerance. Follow applicable shop safety protocols and machine guarding requirements during operation.
