Set of 7/8-14 inch UNF American hand taps
Modern machine taps with through shank for cutting American unified fine threads. These are UNF type inch threads, 7/8 inch diameter - 14 coils per inch. Thread type C (2 - 3 P) - for threading through-holes and blind holes in materials that give short chips. The tolerance field of the threads made is 2B. The most important feature of taps of this type is the ability to withstand very heavy cutting conditions and the possibility of obtaining high machining efficiency. This is mainly due to the special HSS high-speed steel from which the offered machine threaders are produced. This type of tool steel is characterized by very high hardness and wear resistance. In addition, our unified machine threaders are considered to be very resistant to various types of mechanical damage such as breaking, cracking, chipping, breaking out and dulling. They can be used for various types of machine tools, including those cutting at very high speeds.
