Set of 4-40 inch UNC American hand taps

High quality unified hand taps with normal pitch UNC No 4-40, designed for cutting threads in through-holes and blind holes. Made of special HSS - High Speed Steel, whose high technical parameters allow to achieve high quality machining and at the same time increased productivity. HSS unified hand taps maintain high resistance to machining even very hard materials.

They are suitable for cutting threads in parts made of unalloyed (carbon) steels, metals, non-ferrous metals, metal alloys and hard plastics. The thread cutters offered in our store are made by the Czech company Bucovice, which is well-known and appreciated by professionals. This is a company with a long tradition and at the same time conducting constant cooperation with scientific institutions. The results of the cooperation of scientists influence the use of innovative methods of tool production. They translate into high cutting parameters. Taps are suitable for threading holes in parts made of ordinary unalloyed steels, metals, nonferrous metals, metal alloys and thermoplastics.
