Hand Taps - Carbon Steel
DESCRIPTION
aps are used for cutting internal threads in predetermined holes. These perform best in materials where the cutting action results in chips which break up readily and do not present problems of chip disposal. Taps are usually used in sets of 3 (taper, second and bottom) Taper
Used to provide a quick & easy start, but this will not cut the thread down to the bottom of the hole
Second
Used to increase the size of cut
Bottom
Used for follow through right to the bottom to obtain full depth of thread. As opposed to straight threads such as BSW, UNC, UNF, Metric etc; taps with parallel threads are shorter in length and are used for parallel threading. These are used in sets of 2. All taps are right hand taps
