Machine tapping 7/8-14 UNF for stainless steel, American

Professional 7/8-14 UNF machine tapping thread er with through shank in accordance with DIN 374. It is suitable for machine making American unified threads. These threads are UNF type - fine threads, 7/8 inch diameter, 14 turns per inch. The outline of the threads is triangular with an angle of 60 degrees. Type of nut D - with blind and through holes with long thread run-out. The tolerance class of the made threads is 2B. The 7/8-14 UNF unified machine threaders offered to you are made with the highest precision from special cobalt high-speed steel HSSE (High Speed Steel). This specialized tool steel is characterized by high wear resistance even when exposed to high temperatures (up to 600 degrees C) generated during high-speed machining. Thanks to it, the threaders in question are rarely subject to mechanical damage such as breaking, cracking, chipping, chipping and even dulling. They are suitable for machining unalloyed steels, metals, nonferrous metals, metal alloys and others.
