When drilling hardened or stainless steel, select a drill point of at least 135° or higher. This spreads the workload out over a larger cutting surface. Since hardened steel and stainless steel are both quite difficult to drill into, using a drill press or a milling machine should provide the best results.

Try to avoid the cheapest drill bits, or you could likely end up spending more in the long run. Always use cutting oil or coolant for any drilling operation.

Aluminum is very easy to machine, but it’s abrasive, so cutting tools will tend to wear quickly. The best drill bits for aluminum are solid carbide because solid carbide is very hard and stays sharp much longer than other materials, providing extended tool life. If you’re only poking a few holes, high speed steel (HSS) is fine. Using a cobalt drill bit isn’t worth the extra cost because on aluminum, its performance level is about the same as that of high speed steel. Skip the coatings on these drills —there’s no need to increase the already high cost. Especially avoid any coating with “Al” in the ingredients (AlTiN, TiAlN, etc.). A drill bit with a  bright finish is ideal.

Cobalt drill bits are best suited for use on hard to machine metals, including hardened or stainless steel. Cobalt is blended in with High Speed Steel to make the drill bits harder and more wear resistant. As each cobalt drill bit consists of High Speed Steel with a small percentage of cobalt, the higher the percentage of cobalt, the more heat-resistant and durable the drill bit is.
