With a hole digger, holes can be dug cleanly and accurately. Compared to digging holes with a spade, the use of a hole digger is much less complicated and less strenuous.
It is an essential tool for anyone who wants to work something in the ground. The hole digger can be used anywhere where soil needs to be excavated.
Let us help you find the earth drill that is most suitable for you.
How to choose a post hole digger
An earth auger is a tool that digs straight, round holes in the earth. Round holes can be drilled with the earth drill: With force, the earth drill is turned into the earth until it is completely stuck in the soil, then it is lifted out again. The uses of an earth auger are many and varied: from small plant holes to setting fence posts to drilling wells, it can be used anywhere earth needs to be excavated.
Digging holes with an auger is much faster and cleaner than with a spade and shovel. The handling of an earth drill is relatively uncomplicated and thus this tool is suitable not only for professionals but also for laymen.
There are also hydraulic drills with several meters in length and large diameter. These are used mainly in agriculture and construction to dig huge holes in the ground. In this article, however, we will confine ourselves to the hand-held augers.
For which substrate is an earth drill suitable?
Most augers are suitable for soft soil, preferably on level ground. The soil should not be too compacted but of loose texture. Also, many roots, stones, or other solid bodies can be an obstacle for the auger. Loam or clay soils also prove unsuitable.
What else to look for before drilling:
- Weather: Too much rain will muddy the subsoil, so caution is advised. If the thermometer drops below zero, ground frost makes it impossible to drill a hole because the ground becomes too hard.
- Hard surface: conventional augers are not suitable for hard surfaces either. On sealed surfaces, such as asphalt or flagstone, the auger cannot be used easily.
Loose soil is best suited.
Battery Earth Drill
For smaller gardening jobs, a small cordless earth drill is a helpful assistant. Here, you can simply use an ordinary drill with a soil auger attachment.
There are also cordless augers that can drill holes up to 150 mm in diameter. However, it should be noted that these devices can be more expensive than a gasoline-powered earth drill of comparable quality because of the battery.
|Wireless||No immediate start-up must be charged beforehand|
|Location independent||Dependent on battery life|
|Can also drill large holes depending on the device||More expensive in comparison|
|The motor does (almost) all the work|
Motor earth drill
The earth drill with a gasoline engine is your friend and helper when drilling larger holes, for example, for a foundation. They are usually used for holes from 100 mm to 300 mm in diameter.
For holes 100 mm in diameter, a one-man drill is sufficient. For larger holes, a two-man drill is recommended, because the weight becomes heavier, and you can not hold the drill alone. So, despite the motor, the work is also sweaty.
|Large holes (100x300mm)||Cumbersome commissioning|
|The motor does (almost) all the work||Maintenance|

Buying criteria of post hole digger
In the following, we will show you which aspects you can use to decide between the variety of earth drills.
The criteria by which you can compare the earth drills are:
- Drive type
- Drill diameter/length
In the following paragraphs, we explain what is important in the individual criteria.
Should the drill be powered by a motor, electric or hand? The hand-held earth drill comes in at the lowest price but is the most strenuous. However, it is well suited for smaller holes in loose soil where a motor-driven earth drill would be almost “overkill.”
Electric earth augers and gasoline-powered ones are in about the same price range. The advantage of the motorized earth drill is that it can be used to drill anywhere as long as there is gasoline in the tank. With the electric earth drill, on the other hand, you are tied to the length of the cable. For deeper holes with larger diameters (from 100mm), a hand auger quickly reaches its limits. For this purpose, machine drills are clearly suitable.
When buying an earth drill, not only the drive of the device plays a role, of course, but also the drill itself. Most earth drills come with different drill heads that vary in diameter and length. So there is something for every need. However, the drill attachments can also be purchased separately at a later date.
The diameters of the drill heads can be selected individually.
Since a soil auger is not an everyday tool, and you will also invest some money when buying it, you will naturally want to purchase a good quality device. When comparing, you should make sure that the auger is made of materials that are durable.
When buying, you should make sure that the auger is made of a powder-coated material. Stainless steel, for example, is a good choice. After all, the auger should be sturdy and robust and not exactly break when it hits a rock. It should also be able to drill through loose roots.
To get a nice hole, not only the potency of the earth drill plays a role, but it depends solely on the subsoil. As explained in the section “For what kind of ground is an auger suitable?”, the condition of the soil has a great influence on a successfully drilled hole.
Loose, preferably sandy soil is best suited. Small stones are usually no obstacle. However, as soon as the soil is riddled with roots and large stones or even rocks are in the way, nothing can be done even with a powerful power auger; it gets stuck.
