noun. : a hand tap cutting a full thread to the bottom of a hole.
Bottoming Tap
Bottoming Taps are useful for threading blind holes. It's desireable to thread most of the hole with a Taper Tap first, and then finish the bottom of the hole with a Bottoming Tap.
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. When rotated by hand, the bottoming taps chamfer is too short to start a thread because all the thread form would be removed with only 1.5 threads of the tap.
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.
Bottoming taps have almost no taper and have continuous cutting edges until the end of the tap which allows it to cut threads to the bottom of a blind hole, or a hole that does not go completely through the material. Because they do not have a tapered point, they cannot begin a new tap.
The one with the longest lead is referred to as the taper or the first tap. The second or intermediate tap and the third which has a very short lead, as the bottoming or plug tap. The bottoming tap (plug) is used to finish the threads of a blind hole to the correct depth.
Tapping tools are divided into four types: straight flute tap, spiral point tap, spiral fuse tap and forming tap.
A damaged or loosened tap washer is likely to be the reason you have a dripping tap. All you need to do to replace it is unscrew or slide off the original washer and screw or slide on a new one. Make sure it is tight and an exact fit for your tap.

Modified Bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading to the bottom of blind holes and have 2 to 2-1/2 chamfer threads. Taper chamfers, also known as starter taps, have a longer chamfer and require a less aggressive cutting action.

Semi-bottoming are usually 2 to 2-1/2 threads long, and modified bottoming range between 2-1/2 and 4 threads long depending upon the style of tap. The additional length is used to reduced chip load, add tool life in difficult to machine materials and to allow higher tapping speeds.

A screw thread insert tap, or STI tap, operates in the same manner as a "standard" tap. However, the difference is that STI taps produce an oversized thread specifically for E-Z Coil™ inserts.
The difference between threading and tapping is the tool used and the surface on which the processes happen. The threading process creates threads outside of a hole with a die tool. The tapping process makes threads inside a drilled hole with a tapping tool.
