Drillco 115 piece jobber drill set. Designed for general purpose drilling under a wide range of drilling conditions. It can drill various materials such as cast iron, steel, and steel forging. The surface treatment prevents chip welding, improves chip flow and increases abrasion resistance. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.

Fine for the price. We use mostly with aluminum. Dont like the case, though.
Building robots with students, we needed a full set for drilling mostly aluminum. These are fine for that and the price was great. We have used these also for drilling stainless steel on occasion with no problem. For replacements in my own shop I buy cobalt because they stay sharp longer, but a full set would break the budget.Note these have a conventional point, which I like better than the 135° facet points for use with spotting and pilot drills.Update: I ended up buying three cases for the number, letter and fractional sets because this case is not really secure for the small number drills, which kept falling into the bottom of the case. The quality of the drills is fine for our work with aluminum, but the commonly used sizes do wear out and ibreplace them with higher quality cobalt drills.
