What Drill Bits To Get???

If the cobalt bits only have a cobalt coating, Does that mean they can't be sharpened and still keep the integrity of the bit? Where do you recommend buying them?

They can be sharpened. They won't work as well as they did new. Do you have a industrial supply or fastener store nearby? Check out the tool department at a farm store also. I don't pay much attention to tools and where to buy them. I get enough of that 60+ hours a week. LOL
