If you are drilling stainless steel or other tough tool steels
you will need genuine cobalt alloy steel drill bits.
This set is made from M35 High Speed Steel.
M35 has 5% Cobalt, this is the difference between H.S.S. Steel and Cobalt High Speed Steel.
There are fake cobalt drills out there so be sure to purchase the real thing.
