I'm building up my tool collections, much of it from the ground up as I have just moved into a house and now have room.
The time has come to purchase a good set of drill bits. My first question is this: Are the craftsman pro zirconium nitrate coated bits at least of a mid grade quality? Reason I ask is, the combo kits that Craftsman Pro has offer a lot of the bits/accessories and common drill sizes I want, and the benefit of the quick-change type system. However, I'm not going to invest into a large kit if the bits are poor quality.
Next question is, I want to get a good set of drills that will be good for general use on wood and light metals. I'd like something that will last, and I also plan to get a drill doctor to keep bits sharp. With that in mind, do I go with cobalt bits? They seem to be most highly recommended as Cobalt bits are actually an alloy in the steel and make them stronger than a standard HSS set. Would I benefit from a TiN coated Cobalt set?
What manufacturer makes quality sets of drill bits? As many others have set, TiN/Zirc/whatever coating on crap, is still a crap drill bit. I want to invest my money in quality bits.
Thanks!
