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.

This article covers the important issues that influence the successful machining of these steels.

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.

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.

Threading insertspecifications

Thread turning is another option for making internal threads when tapping conditions are not optimal, such as parts with large diameters or in difficult-to-cut materials. Thread turning is most often performed on a lathe with a cylindrical workpiece and uses an indexable carbide insert with a boring bar. When boring bars are too large for the size of hole, a solid carbide threading bar can be used. In thread turning, the workpiece rotates as the cutting tool moves axially to create a continuous thread path. Like thread-milling, it normally takes multiple passes to generate a full thread profile. Unlike a thread-milling cutter, all the material removal is accomplished with only one cutting edge engaged. Removing only a fraction of the thread depth in each pass keeps the cutting edge from being overloaded.

A good quality High Speed Steel (HSS) drill bit is suitable for use on mild steels, but if you need to get a lot of use from them, go with M35 cobalt drills, or even the aforementioned M42 cobalt drills.
