Different Types Of Taps & When To Use Them: Taper, Plug, Bottoming Tap, Spiral And Straight Flute Taps
A taper tap is rarely the final tap used before completing a project however, as the taper leaves incomplete threads cut at the bottom of a blind hole.
A plug tap has a less pronounced taper to the cutting edges. This gives the plug tap a gradual cutting action that is less aggressive than that of the bottoming tap but more aggressive than a taper tap. Typically, the plug tap will have 3 to 5 tapered threads before the full cutting diameter is engaged.
Plug taps are great when used with through-holes, as they are almost as easy as taper taps to start, but also offer a more complete set of threads.
The third style is a bottoming tap. Bottoming taps have 1 to 2 tapered cutting edges before the full cutting force is engaged. Though this tap is extremely hard to start threads with, it is capable of cutting threads all of the way to the bottom of a blind hole. Bottoming taps are best used after a taper or plug tap has been used to cut the initial thread.
At ProMAXX Tool, our thread repair and ProKit Plus tools all come with machine-grade bottoming taps. We are able to provide this right off the start of tapping because the ProMAXX ProKits allow for the guide bushing to keep perfect alignment of the tap during the entire repair.
