Machine Tap, 1/4in. x 28 UNF, Spiral Flute, Vanadium High Speed Steel, Steam Tempered

Made from a super grade high speed steel with extra vanadium content. This has a distinct advantage with taps, by increasing wear resisting properties and extending tool life significantly. These taps are intended for general application where consistent results and improved tool life are important. Threads can be produced in a range of steels, including stainless and cast steels as well as some long chip non-ferrous materials.
