When are you going to stop fooling around with inferior hand drilling technology and get a real drill holder?
The Merrick Bayonet is the only way to go.
The Merrick Bayonet + Dammer = 5 minute bolt placements
I was talking to Tom Davis a couple weeks ago and he was explaining this drill holder that ratcheted, or something like that. It sounded bizarre and it mostly went over my head as to how it worked. I just nodded and said it made total sense to me, which it didn't. Anyways, it was a homemade sounding job that, as he claimed, would get a hole drilled in mere minutes.
Aaron, or anyone else, has Tom ever mentioned this dubious sounding master of all Pinnacles drill holders?
