Cleveland C04565 Screw Machine Drill Bit 23/64 in Hss

Product Description

The CLEVELAND C04565 is a screw machine length drill bit designed for fast, accurate hole-making in a wide range of materials. Built from high-speed steel (HSS) with a bright/uncoated finish, it features a 118-degree standard point angle and a web-thinned tip that reduces entry force and improves centering. At 23/64 inches in diameter and 3-1/16 inches overall length, this short-series bit is sized for use in tight spaces where a jobber-length bit would not fit. It is a general-purpose tool suited for machinists, fabricators, and maintenance technicians working with drill presses, lathes, or CNC equipment.

This bit is appropriate for drilling into alloy steel, aluminum, and similar workpiece materials in both production and maintenance environments. The screw machine length form factor makes it a common choice for turret lathes, screw machines, and bench drill presses where stub-length tooling is required. The straight-cylindrical shank seats directly into standard drill chucks without adapters, keeping setup time low. It conforms to ASME B94.11M standards and falls within the Series 2120 product line.

Key Features

• 23/64 inch (0.3594 inch) diameter with a tight tolerance of +0.0000 to -0.0010 inch
• 118-degree standard point angle with web-thinned tip for reduced thrust and better self-centering
• High-speed steel construction for general-purpose drilling across a broad material range
• Short screw machine length overall length of 3-1/16 inches suits confined-space and machine-tool applications
• Two-flute regular spiral design promotes efficient chip evacuation
• Right-hand cut with straight-cylindrical shank for direct chuck mounting
• Meets ASME B94.11M standards

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks accepting a 0.3594-inch straight-cylindrical shank, including drill presses, turret lathes, and screw machine setups. Suitable for workpiece materials including alloy steel and aluminum per Series 2120 specifications.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with proper drill press or lathe operation. Ensure the machine is powered down and the chuck is fully secured before inserting or removing the bit. Do not exceed the recommended feed rate or spindle speed for the workpiece material, as overheating will degrade HSS tooling. Eye protection and appropriate chip guarding are required during operation.
