Taps are used to cut and restore internal threads precisely. A tap is used to form the female component of the assembly, as in the case of a nut or socket. Tools like a T handle wrench are used with a tap to create or repair an internal thread.

Taper taps are most often used when the material to be tapped is difficult to work with or if the tap is of a very small diameter and prone to breakage.
Taper Taps in this selection are made of high speed steel and are available in Metric Coarse Sizes.
Tap sizes should be one size larger than hole to be tapped. For example: M4 Hole = M5 Tap
