Cobalt drill 3/32"
By cjb from Old Saybrook, CT

Bought several of these expecting them to break or dull quickly, have to admit one bit did the job drilling through a lot of hard steel. Pleasant surprise to be fully satisfied with this purchase.

Best for stainless steel
By Cliff from Onset, MA

I needed to drill additional holes in my SS pulpits. Ordinary HSS drills didn't work for beans. The cobalt drills were the only ones that worked.
