Drill Bits

I'm sick of my drill bits. They are "General Purpose" bits that never stay sharp and break very easy. They do a fair job on wood, but really struggle drilling metal. I'm looking to buy a new set. My buddy told me to buy Cobalt bits, he's been very impressed with his.

I know there are many material used to make bits.

What is the best overall type for long life, sharpness, and can used to drill hard metals.

I have learned over the years some basic do's and don'ts about drill bits. First don't fall for the "titanium" coated bit trick. No coating will strengthen a bit. Buy a good bit sharpener and extra sharpening wheels, and learn how to use it properly. Don't buy bargain basement deals, for after all you get what you pay for. You may spend a little more initially for good quality bits, but if you take care of the bits, don't put too much pressure on them, drill straight, let the bit do its job, you will be a happier camper. Cobalt, Black and Decker, Bosch, and others make good bits, so you will have to choose the ones that will fit your budget. Good luck with your endeavors, and post back if you need more info.

IIRC, there was a thread awhile back about bit sharpeners. A lot of opinions about what brand was best. I have a Drill Doctor and for the money I'm very pleased w/ it. You might try one on your old bits. Doesn't make them any harder, but you sure get a sharp and true edge quickly and easily.

I seldom ever use the same bits for both wood and steel. I prefer the cobalt bits when drilling steel. They cost more but stay sharp longer. It is also a good idea to use lubrication when drilling metal of any thickness.

Thanks guys.

I know you get what you pay for. Price wasn't really an issue, I was looking more from a anti-frustration view.

I found a 29 piece cobalt set (1/16 to 1/2) in a nice steel case for $120 (averages a little over $4 per bit). I will also invest in a good quality sharpener.
