      Rated 1 out of 5�by cobalt drill bits Bought a new set of bits yesterday and I needed to drill6 holes through both 1/8" & 1/4" Angle iron bed frame material. The cobalt bits I bought failed miserably, could hardly get it done. Ended up having to step drill to get 6 - 1/4" holes through the material. I won't buy Irwin bits again!! April 1, 2015
      Rated 5 out of 5�by Mr. These cobalt drill bits are the only thing that will drill into hardened bolts and metals. I have tried standard bits on hardened metal before not knowing what grade the metal was. The standard bit dulls almost immediately so I reach for the cobalt bits. They will sink on through the metal with no problem. The only cons are they are more expensive and they will break easily if you put force perpendicular to the bit instead of linear. May 28, 2013
