I have different sets for wood working and metal working, and a ton of loose bits that I sharpen and destroy as needed, lol. I have a set of forstners from rockler, brad points from rockler I think, I keep a complete set of dewalt drill bits on the wood shop. I think I have 2 sets of spade bits in the wood shop and a bunch of loose spade bits I use for electrical work. I have a couple of sets of twist drills in the garage for mechanical stuff but the smaller sizes always seem to get broken and not replaced, drilling out broken bolts and such. I do like cobalt bits for metal working as they stay sharp longer. They say you need to wear a respirator when sharpening them though. I learned a long time ago how to sharpen drill bits by hand and by eye, an old school tool maker taught me how to do it when I was a young pup, that has proved to be one of the most used things I was ever taught. I don't need fancy jigs and such for metal bits, but I do need my glasses for smaller sizes now, lol.

I just have muscle memory for the angles and hold the bits to the grinder by hand. Oh, almost forgot about hole saws, lol, got a bunch of them too. Ok this was weird, I never really gave much thought to how many drill bits and types I have. Maybe I should make a list and complete the drill indexes I have........yeah right, like I'll remember to do that..........
