T-15 is a grade of cobalt tool steel, which offers the highest hardness of most common high speed steel grades.

This heavy-duty, high-speed steel grade offers maximum cutting-edge endurance and wear resistance due to its high Vanadium content. The Cobalt content additionally lends it high temperature hardness and resistance to tempering.
