Cleveland C57033 Spiral Point Tap 2-64 Unf Hss Plug

Product Description

The CLEVELAND C57033 is a spiral point plug tap designed for through-hole threading in machine and hand-tapping applications. Ground from high-speed steel with a bright uncoated finish, this tap cuts a 2-64 UNF right-hand thread to a 2B class of fit. The spiral point geometry pushes chips forward ahead of the cutting zone, reducing clogging in through-hole work. With an overall length of 1.75 inches and a thread length of 0.44 inches, the C57033 is sized for small-diameter fastener work. It carries an H2 thread limit, making it suitable for standard tolerance threading in a variety of ferrous and non-ferrous materials. Machinists, tool-and-die technicians, and production shop operators are the primary users.

This tap is appropriate for through-hole threading in alloy steel, carbon steel, and aluminum workpieces. The 2-flute spiral point design is well suited to CNC tapping centers and manual drill presses running at moderate speeds with proper cutting fluid. The plug chamfer style provides a gradual lead-in, distributing cutting load across the first several threads. It is commonly used in precision assembly and repair work where 2-64 UNF fasteners are specified.

Key Features

• Spiral point geometry pushes chips forward — effective for through-hole applications
• High-speed steel construction for durability across alloy steel, carbon steel, and aluminum
• Plug chamfer for gradual thread engagement and reduced tool stress
• H2 thread limit for standard 2B class of fit tolerances
• Bright uncoated finish — ready for use with standard cutting oils
• Right-hand cut, 2-flute design compatible with CNC and manual tapping setups

Compatibility

Designed for through-hole threading applications requiring a 2-64 UNF right-hand thread. Suitable for use in alloy steel, carbon steel, and aluminum workpieces as noted in manufacturer specifications.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians in shop environments. Before tapping, ensure the pilot hole is drilled to the correct tap drill diameter for a 2-64 UNF thread and that the workpiece is securely fixtured. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Never force a tap against resistance — back off periodically to break chips and prevent tap breakage.
