Subject: Re: [OldTools] auger forging

Gary inquires about the rationale for solid center augers.

My (possibly incorrect/incomplete) understanding is that solid center augers
are supposed to be less likely to flex when drilling very long/deep holes.
Therefore, I infer that they may also be able to handle more torque than a
twist auger bit might (as when driven by a power drill). As far as how they
are made I have no knowledge, but they look like they could be either milled
from solid bar or forged/swaged.

On a related note, another galoot asked me off-list whether the company that
had the auger factory in the video I mentioned the other day was still in
business. Apparently it is not. The company was Clico, of Sheffield, and it
looks like it went out of business almost exactly three years ago.   :-(
