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.

Make sure you get the correct inserts for your indexable turning tools.
