The ultimate hole boring tool is the drill while the ultimate drill bit is an auger drill. Just like there are different types of drills there are different types of auger drill bits. But what is an auger drill in the first place? An auger drill bit is just like any kind of drill bit but the difference with augers drills is that they can be used for different tasks and come in sizes between 5 and 45 cm.This level of versatility makes auger drills usable in different scenarios such as woodworking, drilling into ice, clearing a clogged sink, digging irrigation trenches, drilling a hole for a telephone pole, and making a hole in the ground for a tree and so on. Auger bits can also be attached to heavy machinery and used for commercial construction. But which type of auger drill do you use and when?
Benefits of Using Auger Drills

Quality
If you want a drill bit that is able to provide a smooth and easy drilling procedure, auger drills are the way to go. They are known to make quality holes that are uniform and smooth to the very end. A proper augers drill does this thanks to the guide screw which guides you through the material you're drilling in.
Depth
If you want to drill deep, a drill auger bit is also a great option since you can make holes up to 600mm deep. This is when it comes to wood, there are auger drills that can drill even deeper through materials stronger than wood.
Shavings
When a material like wood is prone to generating shavings when drilling through it, augers drills are here to save the day. Not only are they quite capable of drilling deep they are also capable of drilling efficiently. By efficiently I mean, neatly, since they are able to get rid of shavings quite effectively. This feature of augers drills allows you to keep your borehole free from debris, so you don't have to use your air compressor or mouth to blow the shavings out of the hole.
Types of Auger Drills
Wood Boring

If thick pieces of wood are a constant occurrence on your workbench, then drilling through them is best done with a wood-boring auger bit. This is one of the most commonly used auger drill bits that can easily help you make a pipeline for an electric able that needs to run through a wooden piece. These spiral-shaped makes can make for clean and deep holes and can be used with both hand and power drills as well as drill presses.
Carbide-Tipped
Although quite similar to wood-boring auger bits, carbide-tipped bits are made so that they can successfully drill through hidden nails. This cannot be done with other types of auger bits since they do not have the hard tip, that carbide-tipped bits have. Carbide-tipped auger drills can sustain the damage and thus give you a clean hole with ease and last you a long time too. The solid carbide insert of this auger bit can be removed and reattached any time you want.
Grain

Using a grain auger bit is done for a different purpose than that of a carbide-tipped or a wood-boring augers drill bit. With a grain drill auger, you are able to collect grain from a bin or a silo. This is thanks to its unique design which has a twisted segment and a longer “fighting” segment. The bit has the two segments into a shaft or tube that helps keep the retrieved grain into place once pulled or pushed into a silo.
Triple-Fluted
A triple-fluted auger bit is another type of wood-boring drill bit, which unlike the standard wood boring auger bit has quite an aggressive design. This is what allows triple-fluted auger bits to penetrate and cut rapidly through wood stock. But don't expect to get a neat hole with this type of auger bit as its wide-apart fighting and steep spiral flutes make for a messy drilling experience.
Concrete
As its name suggests, concrete auger bits are made to be used to cut through, well concrete. This type of auger bit is much like a wood-boring bit since it makes for an efficient clearance and one that generates very little waste material. Concrete auger bits make for neat holes but with the added resilience of masonry drill bits.
Ice
While this type of auger bit is not something you'll see in everyday construction work, it is however quite an effective solution for its only use. Ice auger bits, cut through ice, unlike any other drill bit. Why would one cut through the ice? Well, in places where constant access to food isn't possible, like Alaska, cutting through ice is an essential part of everyday life. This way locals get their much-needed nutrition in the form of fish.
Earth
To make a hole in the ground that is not going to require any cleaning up after the fact, you should rely on an earth auger bit. Earth auger bits have a rotating metal rod or pipe that has one or more blades found at the lower end. This rotation is what allows earth auger bits to cut or scrape the ground and soil and make an easy way to plant trees and crops.
