Cleveland #0-80 UNF Spiral Point Tap
This Cleveland C57011 spiral point tap cuts internal #0-80 UNF threads in through holes. It is made from high speed steel with a bright uncoated finish for general purpose threading work. The plug chamfer and right hand cut suit standard tapping operations in metal. Machinists and maintenance technicians use it for small precision fasteners.
Two flute design and bright finish
The two flute configuration pushes chips ahead of the tap to reduce clogging in through holes. Bright high speed steel resists wear without coating buildup that can affect fit in tight tolerances. Overall length of 1 5/8 in and thread length of 5/16 in provide reach for shallow holes. The H2 thread limit targets a 2B class of fit for standard assemblies.
Replaces worn or incorrect small taps
This tap upgrades from dull or damaged #0-80 tooling that produces oversize or rough threads. The jump is worth it when thread gauge checks fail or when a 1.20 mm drill size is specified for 75 percent thread engagement. It is not for blind holes needing bottoming chamfers or for left hand thread applications. Builders needing larger diameters or different pitch series must select another size.

Questions about this item
What thread standard does the #0-80 UNF tap follow, and what class of fit does it produce?
It cuts a Unified National Fine thread to a 2B class of fit with an H2 thread limit.
What drill size and shank dimensions are needed for this tap?
Use a 1.20 mm drill for 75 percent thread engagement; the tap has a 1 5/8 in overall length and 5/16 in thread length.
How do you start the tap correctly in a blind or through hole?
Apply steady forward pressure with cutting fluid; the spiral point pushes chips ahead so you must not reverse until the full thread depth is reached.
