Drill bits

The Norseman bits look like the "cobalt" (HSCO) bits that are widely used in the aircraft industry. You can pretty much tell by the color, and the price. I guess the Norseman bits are not exactly HSCO, judging by their description, but sound similar.
By the way, so-called "titanium" bits could be made from anything. The "titanium" only refers to the (usually) yellow coating, titanum nitride (TiN) on them. This really just helps with reducing wear, and adding some lubricity. They don't necessarily stay sharp longer, or are any tougher.
