1987Comanche Posted January 1, 2011 Posted January 1, 2011 One of the IOUs on my list of stuff from Santa was a set of new drill bits. I killed quite a few while making all the adapter plates to put my Grand Am seats in the '90 MJ. I like the way the DeWalt bits cut into the material and I had the cobalt set (not TiAlN High speed steel). Most of my drilling is sheet metal/angle iron/stainless so M35 cobalt would probably be the minimum. Carbide doesn't seem like the best idea b/c of price and how brittle they could potentially be. So what does everyone use in their hand drills?
Pete M Posted January 1, 2011 Posted January 1, 2011 my cobalt bits are phenomenal. :drool: went through spring steel like it was wood. :bowdown:

Darren Posted January 2, 2011 Posted January 2, 2011 DeWalt makes a set with self piloting tips that I really like. Step bits are also real handy for certain jobs too.
jimoshel Posted January 2, 2011 Posted January 2, 2011 Don't know which one is best. Frankly I'd just like to get the hang of how to sharpen one.
