Auger bits are based on an invention from about 2,300 years ago called “Archimedes’ screw.” In the 21st century, they are used to move material and liquid in a variety of tools and equipment. A basic auger bit is a cylinder with a point on one end and groove that runs around the circumference and gradually ascends up the side cylinder away from the pointed end. When the cylinder is rotated, the point can bite into material, and the groove carries the cut material up and away from where the bit is working. Auger bits resemble drill bits, except that the groove is deeper than on a drill bit.
Determine the hole that you need to bore. An auger differs from a drill in the size of the hole. Auger bits generally begin at ¾ inch and go up to 1 ½ inches or more.
Mark the center of the hole you want with a nail point or screw point. This small indentation will allow the point of the auger bit to hold to the material you are boring and get you started.
Select the bit that is the same diameter of whatever you will be inserting into the hole. This will give you a tight fit.
Insert the bit into the drill and tighten the drill around the bit using a chuck key. The end of the chuck key will insert into a hole on the side of the drill. When you turn the chuck key while it is inserted, it will either tighten or loosen the drill's hold on the bit.
Start the drill turning. Turn on the drill or begin turning the handle on the hand drill. Make sure that the auger bit appears to be rising out of the boring while it is turning. This means the bit is turning in the proper direction and moving material out of the hole.
