Cleveland #12-28 Straight Flute Hand Tap

The Cleveland C54392 is a three-piece straight flute hand tap kit designed for cutting UNF threads. It suits machinists and maintenance technicians who need to produce Class 3B internal threads in a range of materials using hand or light machine operations.

Upgrade from worn or single taps

This kit replaces individual worn taps or incomplete sets by providing taper, plug and bottoming taps in one package. The jump is worth it when a workshop requires the full threading sequence to reach full thread depth in through or blind holes without switching brands mid-job.

Sustained threading performance

High-speed steel construction with a bright uncoated finish maintains cutting geometry during repeated hand-tapping cycles. Four flutes evacuate chips efficiently while the 75 percent thread drill size of 4.60 mm supports consistent thread formation across multiple holes without rapid dulling.

Questions about this item

What tap wrench size fits the 2 3/8 in overall length?

A standard adjustable tap wrench opening to roughly 60 mm will grip the 2 3/8 in shank securely; centre the jaws on the square to avoid slippage.

Which of the three taps should I start the hole with?

Begin with the taper tap, follow with the plug tap, and finish with the bottoming tap to cut full threads to the bottom of a blind hole.

When does the 4.60 mm drill bit need replacement?

Replace the 4.60 mm drill once its cutting lips show visible wear or the drilled holes exceed the 75 percent thread engagement tolerance.
