I had a set of Craftsman Titanium coated drill bits. I am pretty sure they were stolen. So I need to replace them. They are $90 for the set. I see Craftsman also has a set of Black Oxide coated bits for $60.

What is the functional difference? I see they are both listed for wood/plastic/metal use. Anyone had experience with them? Will the oxide coated ones require sharpening? I'm pretty sure the titanium ones either didn't require or were not able to be sharpened. Is there a different set I should be looking at?

Black Oxide ones would just be an all purpose style bit. Titanium is going to be the next step up....lasts longer, doens't build up heat as fast.
