IMPA 631399 HAND TAPS set of 3 pcs HSS UNC 2" x 4,5

This is a set of three hand taps made of high speed steel (HSS) and intended for use with UNC ( Unified Coarse) threads. The taps have a two inch (2") outside diameter and a 4.5" length. They are used to create threads in a hole, and the set includes three different sizes of taps ( each with a different number of flutes) to create threads of different sizes. The benefit of using HSS taps is that they can be used on a wide range of materials, including metals, plastics, and composites, and they offer a high degree of precision and durability.
