Machine tapping 1/4-28 UNF for stainless steel, American
High-quality professional 1/4-28 UNF machine taps with reinforced shank for machine cutting of American unified threads, type UNF (fine thread). These are ¼ inch threads, 28 coils per inch. Outline type C (2 - 3 P) - for through-holes and blind holes in materials that give short chips. The threads have a triangular outline (angle of 60 degrees).
The tolerance field of the made threads is 2B. In our store we offer you high-end unified machine threaders produced according to DIN 374/40 from modern high speed steel with 5% cobalt. This unique cobalt steel influences the possibility of obtaining high efficiency of machining, shortening the time of threading a single workpiece, and thus more rational use of your workstations. In addition, our 1/4-28 UNF machine threaders are very resistant to high temperatures (up to 670 degrees C), which enables high-speed machining. The blades of the taps are resistant to mechanical damage, which significantly extends their service life.
