What is an auger attachment?
The Auger is used to drill holes--when drilling, the screw blade pulls the soil out of the ground.
What is the difference between an auger and a post hole digger?
A post hole digger also digs holes. The difference is that they are powered by gas, propane or a battery. They drill holes with less effort than a hand auger and they drill holes faster. If you've got more than 1 or 2 holes to dig, a post hole digger would be a good investment.
