High quality 1/4-28 UNF machine thread cutter for cutting American unified UNF threads. Thread diameter ¼ inch, 28 coils per inch. Thread outline triangles, 60 degrees, tolerance class of made threads 2B. The tapping machine is suitable for machining through-holes and blind holes with a long thread run-out (D-cut). The unified machine taps in question are produced from high-alloy molybdenum steel of HSS grade. This is a modern material used for manufacturing cutting tools with high cutting properties. First of all, our 1/4-28 UNF fine-coil machine thread ers are resistant to harsh working conditions and resistant to mechanical damage such as breaking, cracking, chipping and dulling. As a result, the threaders can be used for a very long time, which significantly reduces the cost of buying new tools. The high cutting performance also reduces working time and makes better use of existing machine tools.
