Every time I look at drillbits for metal at the local
Home Depot I'm totally confused.Which is the best,I see tin
coated,black coated etc.Recently I saw a new line of wood bits from
Milwaukee,they look good but as I said above I'm confused.

My advice would be to stop looking at Home Depot. Try looking at the
online catalogls of MSC, Enco, or Wholesale Tool. Those catalogs are
likely to have a little help on selection. You might also look at
Cleveland Twist Drill. Well actually Kennametal. They own Cleveland
and Hanita.

Now you ought to be thoroughly confused. But the best drill depends
on what you are drilling.

If you are about to buy a set of drills for the first time, consider
buying a set from Harbor Freight, and then buying good quality drills
to replace those that get dull.

Also look in RCM for Robert Bastow's description of how to sharpen
drills freehand on a grinder. I never quite understood his
description, but if you can find someone local to you, they can teach
you how to sharpen the larger size drills reasonably well. It is not
rocket science and worth knowing.
