Daniel,
I was drilling this weekend using a Cobalt 1/2" bit in my HF press. I cleared one hole, went to do another, and it would only drill a divot. I kept it oiled, and kept a lot of pressure on the machine, all I did was smoke the bit and make shit hot. Any idea? I swapped it out with a 3/8" and had no problem drilling that through the same piece. Just my 1/2" bit. Think I screwed it up? I was drilling annealed, so it blows my mind to think that I could have dulled the bit after its first use.
