A tap is a tool which is used for making internal threads in a machine component.
TAPPING TOOL A tap is a tool which is used for making internal threads in a machine component. A tap is a multi-fluted cutting tool with cutting edges on each blade resembling the shape of threads to be cut. A tap is used after carrying out the pre-drilling operation corresponding to the required size. The leading end of the tap is tapered as shown in Figure 3.89 to help to start the tap and to distribute the majority of the cutting actions over a number of threads. This type of tap is used only for tapping through hole. For blind holes, a flat or special bottom taps without a taper have to be used. The thread of the tap may be cut and hardened or cut, hardened and ground. The latter case is used for precision threading operations.
