Digging holes can be quite a hassle and take a lot of time. That’s when you don’t have the right equipment for the job. When it comes to drilling holes for posts, ground slugs can significantly cut the time and effort required to complete the task in half. There are different types of earth snails.

Having an earth snail on hand is something every homeowner should consider. However, for those who work on their land and dig a lot, an earth snail, especially an electric snail, is essential.

Different types of snails

There are also different types of drill bits designed for light to heavy work. We’ll go through these types of drills, as well as the pros and cons of each exercise.

If you have to dig a few small holes in your garden, the one-man snail is enough to do the job. As the name suggests, this snail can easily be used and operated by a single person.

Other advantages of using one-man earth snails are their lightweight construction and generally affordable price. This type of drill weighs around 40 pounds. max, which makes it relatively easy to carry around yourself.

For tasks that involve digging a hole for load-bearing posts, the two-man auger can speed up the process. Again, the name is pretty self-explanatory, as this snail requires two people to work properly and is designed for larger tasks.

Two-man earth snails weigh about 70 pounds. These types of drills also use a more powerful drill motor (160 cc engines). Due to the additional power, this snail is often used on heavy clay, hard and rocky soil.

Different screw sizes

There are various sizes of earth slugs to choose from, ranging from two to twelve inches in diameter. Augers two to three inches in diameter are used with your standard drill presses. These drills are also available in various lengths from seven inches to 48 inches.

The larger snails are those with a diameter between four and 14 inches. These drills require a gas drive head to operate. Four to nine-inch screws are all 28 inches long, with the exception of the 7-inch screw, which is also available in a 16-inch version.

Additional attachments for snails

Ground slugs come with additional accessories / accessories to handle specific tasks like potting trees. The ability to choose different sized drills gives you the flexibility to do different landscaping tasks. For example, if you need to dig deeper, you can simply attach extension shafts to get the depth you want without having to buy new auger bits.

What should be considered before buying an auger?

Now that you are sufficiently familiar with the basics of earth slugs, it is time to learn what to look for when making a purchase. Below you will find instructions on which factors you need to consider when buying a ground screw.

  1. Manual or powered earth drill?

First, you need to determine which type of ground snail is best for your needs. Will you use it rarely and only for digging? A manual earth auger is sufficient as it is easy to use and far cheaper. However, if you are looking to do a lot of landscaping in the future, I highly recommend going for Power or electric earth screw. To make the daunting task a lot more manageable.

  1. Engine engine

A drill’s motor performance needs to be the first factor to consider when you land on a particular product. The motor of a worm ranges from 2 to 5 hp. The more powerful motor is best for drilling and digging in harder soils.

You’ll also have to choose between a two-stroke or a four-stroke engine. Two-stroke engines are cheaper but require regular maintenance and are also quite noisy. The four-stroke engine is quieter and easier to maintain, but more expensive.

  1. Diameter size of the drill

As mentioned earlier, you get a variety of options when it comes to the diameter of the auger bits. You can choose from 2 to 12-inch auger bits for one-man augers, while two-man auger bits are up to 14 inches in diameter. Know the diameter of the rods that will be placed in order to choose the correct drill bits.

  1. Drilling depth

Finally, you need to find out how deep the snail should dig. High-performance earth augers are suitable for drilling deeper holes. The standard depth an earth snail can reach is usually around 2.5 feet. However, with an extension you can dig up to 7.5 feet.


As you can see, selecting the right auger for the job is relatively easy when compared to other hardware tools. All you have to remember is the diameter and depth of the hole, and from there you can land on the correct auger.
