High toughness and good cutting power owing to its well-balanced alloy composition; thus suitable for a wide variety to applications. It is used to manufacture knives, thread cutting & twist drills, sendizimer rolls, taps, broaches & milling tools, reamers, metal/circular saws, wood working & cold forming tools. TGM2A is a special grade containing low percentage of carbon to increase toughness & added Niobium to find crystal grains of steel to obtain high strength & toughness specially suited for taps & tabs of thread tools.
