What knife arrangement does the earth auger have?

The most common screw design for earth auger has a spiral blade (spiral blade) wound around the lower part of the shaft. The lower edge of the worm blades scrapes off the dirt at the bottom of the hole, and the rest of the blade acts like a worm conveyor, lifting the loose earth to one side. When the hole reaches the desired depth and the tool is pulled out, the screw blade scoops out the remaining loose dirt. The end of the earth auger bit can be a sharp tip protruding below the spiral blades. Its purpose is to push dirt that is under the bar to the side where the blade can pick it up. It also helps to prevent the drill bit from moving sideways and keeping the hole straight. The lower edge of the spiral blades may have teeth.

What does a earth auger with two rows of blades look like?

Another type of earth auger has two vertical blades instead of spiral screws. Instead of scratching the bottom of the hole, this type of drill cuts a cylindrical plug out of the hole, which is held in place by friction between the two blades. The snail must then be pulled out and emptied every foot or so. This type may require less force to operate, but may only be suitable for certain soil types.
