    Kobalt is a company, but as far as I know, they only put out titanium and high speed bits at Lowe's, not cobalt bits - don't get them, they'll dull in a second on metal.

    Lowe's does have DeWalt cobalt bits, and those are pretty much the only ones I get over there. They're fairly cheap when you get the sets on sale and they will cut very well. The tips have a tendency to lose bite from chipping and the thinner ones will crack a lot faster than the high speed steel ones - take some care drilling and you won't have a problem. I generally buy several of the smallest ones and have a couple back-up sets - I ain't that careful :D

    That, and the life of the bit will be extended if you use a little oil to help extend the life of the bit when your chewing on metal.

    I'm partial to Diamond Bits,


    Oh you mean for the hand held drill!

    Try Dewalt, I usually get decent usage out of them. But in reality you are better off getting a bit sharpener as bits these days are junk really.

    I buy all my GOOD drill bits from McMaster Carr http://www.mcmaster.com/# . They "ain't cheap" but you get what you pay for. When you are looking for a drill bit there, McMaster Carr has a million different types for any given size. Jobber length (the most common ones are that length), short, long, HSS (high speed steel), cobalt, carbidel, titanium nitrided, right hand, left hand, etc.

    AND they have sets from under $50 to HUNDREDS of $$$! Once you place an order with them, they ship it out the next day. I usually get it in under three days from the day it ships from them but they're only in NJ and I'm in NY.

    Practice with your old bits and learn to sharpen them yourself. From what little experience I had with the Drill Doctor, don't waste your money on them. If you can get the knack for the right angle and a back cut, you can make drill bits last forever with about a 30 second resharpening when it's needed. I have some bits I've been using for years, cut down to about 1 1/2" left above the shank.

    Carbide. hands down. But there so brittle they shatter if you drop them. I don't know where to buy them, McMaster Carr sounds good though. My brother in law runs a small CNC company that makes specialty cutters. He usually drops a hand full of stuff off, like end mills and drills every now and then.

    They are used in every machine shop, small or large, especially the large ones.

    cleveland! And a drill doctor, I love mine, although my dad (40 some years)and myself (for a short time period) were machinists, I never got the skill from him or from my work to sharpen a drill bit correctly. The drill doctor does a great job.
