Threading Tool Specification

The Cleveland C54766 is a straight flute hand tap designed for creating internal UNF threads. It suits machinists and maintenance technicians who need to cut precise 9/16"-18 threads in a range of materials.

Compatibility Check

Verify that the workpiece material is suitable for high-speed steel tooling before use. Ensure the drilled hole matches the 75 percent thread drill size of 12.90 mm for correct thread engagement. Confirm the application requires a Class 2B fit with an H3 thread limit.

Operational Characteristics

The bright uncoated finish on high-speed steel provides standard wear resistance during manual tapping operations. A right-hand cutting direction with a 1 inch thread length produces consistent results. The plug chamfer style assists with starting threads in through-holes or deep blind holes.

Questions about this item

Does the Cleveland C54766 tap come with a handle or drill bit, or must those be purchased separately?

The tap is supplied as a single cutting tool; a tap wrench or compatible holder and the 12.90 mm drill bit for the 75 percent thread are not included.

The listing shows only the 9/16"-18 UNF plug version — are other thread sizes or chamfer types available under the same model?

Model C54766 is specific to 9/16"-18 UNF with a plug chamfer and H3 limit; different sizes or tapers carry separate part numbers.

What does the H3 thread limit and 2B class of fit mean for the finished hole in practice?

H3 places the pitch diameter slightly above basic size, producing a 2B fit that balances easy assembly with secure engagement for general-purpose fastening.
