#FORM TAP VS CUT TAP MANUAL#

If you want to buy a tap, then you have to choose between manual and machine use.

A blind hole, on the other hand, only extends a little way into the component. A through hole is drilled completely through a component so that the tap exits on the back side.

The shape of the head also indicates whether the tap is suitable for a blind hole or a through hole. In addition, the head usually has a straight or spiral groove for chip removal. The dimensions for this are specified by the various thread standards. The thread profile on the head determines the type of thread. They are drills that cut a thread in a prepared hole. Taps are the corresponding taps for internal threads. In addition to the round shape, there is also the hexagonal tap, which is mainly used for re-tapping and thread repair. The thread lands specify the thread profile that can be cut with this tap. On the inside, there are the peel cut, the threaded part with the thread lands and the chip holes. On the outside of these cylindrical tools are holes for the retaining screws and a V-groove.

Taps for external threads are called dies. When you buy taps, you should therefore pay particular attention to the correct thread standard. This means that the male and female threads always form a pair and are also standardized accordingly. The female thread is found in the receiving drill hole or nut, the male thread on the matching screw. A thread always consists of two parts, an internal and an external thread.
