Straight Flute Hand Tap #0-80 UNF

The Cleveland C54025 is a straight flute hand tap designed for cutting internal UNF threads. It suits maintenance technicians and hobbyists who need to create or repair fine threads in metal components.

Taper Lead for Starting New Threads

A taper lead with two flutes eases entry into a drilled hole and reduces the risk of cross-threading. The design replaces a bottoming or plug tap when the work requires starting threads in a through-hole or blind hole with sufficient depth.

High-Speed Steel Bright Finish for General Use

High-speed steel construction with a bright uncoated finish handles standard ferrous and non-ferrous materials. The 1.63 in overall length and .31 in thread length fit common tap handles, while the H1 limit and 2B class of fit match a 75 percent thread depth drilled with a 1.20 mm bit.

Questions about this item

What drill size do I need for the #0-80 UNF tap to achieve 75 percent thread engagement?

Use a 1.20 mm drill for 75 percent thread engagement with this #0-80 UNF tap.

How do I start the tap straight in the hole and avoid breaking the flutes?

Apply steady perpendicular pressure while turning the taper lead slowly; the 0.31 in thread length engages quickly, so reverse often to clear chips.

When should I replace this high-speed steel tap?

Replace the tap when the cutting edges dull, chips clog the two straight flutes, or the H1 thread limit no longer produces a 2B class fit.
