What is a plug chamfer?

These are the tapered or incomplete threads at the front of the tap. The taper chamfer has 7 to 10 threads tapered, the plug chamfer has 3 to 5 threads tapered, and the bottoming chamfer has 1 to 2. Generally a taper chamfer, often referred to as a “starter” tap, is used for roughing or sometimes heat-treated material.

Likewise, people ask, what is the difference between a bottoming and plug tap?

Taper taps are normally used in through hole applications or as a starter tap for blind holes. Plug taps have a 5 thread chamfer. In blind hole applications, Plug taps are used after a Taper to get closer to the bottom of the hole. Bottoming tap have a 1.5 thread chamfer.

Additionally, what is a plug style tap? Plug Taps, with a chamfer over four threads, is most widely used in through holes and where there is sufficient room at the bottom in blind holes. Bottoming Taps are made with just enough chamfer for starting in the hole, only 1 to 2 half threads. As the name implies, it is designed to thread blind holes to the bottom.

Subsequently, one may also ask, what are the 3 types of taps?

There are two types of Hand Taps:

• Taper Tap. A taper tap has quite a lot of taper to help it ease into cutting threads gradually.
• Bottoming Tap.
• Plug Tap.
• Spiral Point Taps (Gun Nose or Bull Nose Taps)
• Spiral Flute Taps or Gun Taps.
• Interrupted Thread Tap.
• Pipe Taps.
• Form or Roll Taps (Thread Forming Taps)

What is a bottom tap used for?

A bottoming tap is usually used to cut threads in a hole that has already been partially threaded using one of the more tapered types of tap; the tapered end ("tap chamfer") of a bottoming tap is too short to successfully start into an unthreaded hole.
