Frequently Asked Questions:

Q. What is a plug-style tap?

A. The cutting edges of a plug tap have a less pronounced taper. This results in a plug tap with a more aggressive cutting action than a bottoming tap but less aggressive than a taper tap.

Q. Why are the ends of the taps chamfered in taper lead?

A. The chamfer's primary function is to allow the first few cutting teeth to make progressively deeper cuts. This reduces the amount of force required by the user to spin the tap as well as the tool's wear.

Q. Why do you chamfer a hole before tapping?

A. Chamfer guides the tap into the hole and provides a smooth entry for the tap as it begins to cut or form the initial threads, resulting in longer tap tool life. Chamfering the hole also results in a stronger, higher-quality thread.
