Auger Bits

An auger bit is the tool of choice if you want to drill very deep holes, perhaps with larger diameters. Compared to the twist drill, the auger bit has several advantages: For relatively shallow holes, a normal twist drill can also get the drill chips out of the hole. The deeper the hole, however, the more difficult this becomes. The auger bit has particularly deep spiral grooves in which the chips are transported upwards. This avoids having to pull the drill out of the hole because it is clogged. Auger bits also have a centring spiral tip. This makes the work easier because the drill drives itself into the material in a self-cutting manner.
