Diameter
Your auger diameter is going to determine how wide the hole you dig is. While you can expand the hole’s diameter with multiple digs, it’s not the most efficient or effective way to get the job done. To make the most of your auger drill, we recommend purchasing multiple sized augers that are easy to change out to create different diameters. This way, you can quickly and efficiently dig your hole to the exact specifications you need, in one drill.
Depth Capacity
Another element to consider while selecting the best earth auger is its depth capacity. Some projects necessitate going further than your auger alone. Bunyip Equipment stocks a range of extensions that will help you go the extra distance, both figuratively and literally.
Type & Teeth
There’s a range of surface conditions you may be digging in and knowing what auger attachment to choose can really make a difference. This will come down to how the auger has been designed, along with the teeth it uses. For instance, if you’re just handling average soil or dirt, bladed teeth are best on a tungsten auger. The bladed teeth quickly cut through the soil while the tungsten auger allows you to drill precisely and it is extremely hard wearing. Alternatively, if you were looking to drill through tough rock, you’d want a rock auger with rock pick teeth. While it may be a little more slow going than your standard auger, these are serious pieces of equipment, able to penetrate and break apart hard rock far quicker than other options.
Machine Capacity
Finally, you must consider your machine's capacity and connections. Auger drives and auger attachments are hydraulically operated and require specific flow rate from your machine. Size does matter when purchasing your auger drill and attachments and it's not always a case of bigger is better! It is worth taking the time to find out which earth drill is suited to your machine and what attachments it can handle, without overworking your equipment. A simple conversation with our experts can put you on the right track and get you working with the augers best suited for the job.
Basic Auger Drilling Methods
Auger drilling is a drilling technique that uses a helical screw to drill into the earth and transport the drilled-out material to the surface. It’s a simple yet effective drilling method.
Hand Auger Drilling
Hand auger drilling, as the name implies, involves manual labor. It’s common in areas with shallow soil layers or when detailed investigations of the upper soil layers are necessary. It’s a cost-effective method, but it can be labor-intensive and time-consuming.
Hollow Stem Auger Drilling
Hollow stem auger drilling is a versatile and commonly used technique. It involves using a large, hollow stem auger that drills into the ground, removing soil as it digs. This technique allows for continuous soil sampling in environmental and geotechnical investigations.
Solid Flight Auger Drilling
Solid flight auger drilling employs a solid stem auger to bore into the ground. Drillers commonly use this process for drilling in stable rock formations or intricate soil layers. This method, while efficient, doesn’t allow for continuous soil sampling.
Bucket Auger Drilling
Bucket auger drilling works best for larger projects requiring deeper drilling. The bucket auger removes loose soil and rock fragments in a bucket-like fashion, making it ideal for unconsolidated formations. However, it doesn’t work as well for hard rock or soil layers.
Advanced Auger Drilling Techniques
Beyond the basic techniques, advanced auger drilling methods cater to specific needs and challenging environments. Understanding these can broaden your toolbox of drilling solutions, improving your adaptability and efficiency in various projects.
Double Auger Drilling
Double auger drilling, or dual rotary drilling, uses two augers working in unison. The upper auger drills a hole in the ground while the lower auger removes the excavated material. This method is beneficial in areas with loose or unconsolidated soil layers, as it minimizes the risk of borehole collapse.
Displacement Auger Drilling
Displacement auger drilling uses a specialized auger to displace the soil laterally, creating a hole without removing any material. Displacement auger drilling is necessary only when the soil’s surrounding integrity needs maintenance, such as installing heat pump systems in the ground.
Sonic Drilling
Sonic drilling is an advanced technique involving a drill using high-frequency mechanical oscillation into the ground. This method reduces friction on the drill string and auger, allowing for faster and cleaner drilling. Sonic drilling is particularly beneficial in sensitive environments where minimal waste generation is a priority.
Continuous Flight Auger (CFA) Drilling
Continuous Flight Auger (CFA) drilling is an advanced method often used to construct deep foundations. The process involves drilling to the required depth and then pumping concrete through the hollow stem as the auger slowly withdraws, creating a continuous pile. This technique is ideal in situations where maintaining the stability of the borehole throughout the drilling process is essential.
Traditional Method
Prepare Your Tools: Gather a variety of shovels, a clamshell digger, and a steel spud bar.
Dig a Pilot Hole: Use a pointed shovel to dig a pilot hole at your desired location. This should be a shallow hole that marks where your post will go.
Remove Topsoil: Use a flat-edged shovel to remove any topsoil around the pilot hole.
Deepen the Hole: Insert the clamshell digger into the pilot hole and open its jaws to grab soil. Lift the soil out and set it aside. Repeat until the hole is deep enough for your post.
Break Up Obstacles: If you encounter rocks or hard soil, use a steel spud bar to loosen them. Pry at the stones and soil until you can remove them with the clamshell digger.
Note: This method requires frequent bending, lifting, and prying, which can be strenuous on your back.
Using an Auger
Prepare Your Tools: You’ll need only an auger and a shovel to dig a pilot hole.
Position the Auger: Place the auger where you want the hole to go. It can be beneficial to remove the sod so the auger immediately starts drilling and does not get tangled or clogged with the sod.
Operate the Auger: Turn on the auger and allow it to drill into the ground. Make sure it drills to your desired depth.
Remove the Auger: Once you’ve reached the desired depth, turn off the auger and lift it out of the hole.
Both methods for digging post holes have their merits, but they offer different advantages depending on your needs and physical condition.

Storage
Store in a dry place to prevent rust and damage.
Dig, or “drill,” holes quickly. If you’ve ever drilled a hole in wood or drywall to insert a screw, this Power Planter auger does essentially the same thing. Instead of wood or wall, you’re drilling a hole into garden soil. And instead of inserting a screw, you’re inserting a plant into the ground.
Just position the drill and auger right where you want the hole and squeeze the trigger. It’s fast, too. My soil is average to nearing on soft, and at the moment it’s not terribly rocky. I could dig a hole in about 5 seconds. A trowel takes way longer. As for hitting rocks — I’ve hit a few small ones, nothing bigger than a malt ball. A few times the auger would stop turning, similar to when you drill a hole and drill bit can’t go further into the wall. And a few times the auger spit them out of the way.
A ring of soft backfill. Like sawdust when you drill into wood, the auger’s swirling action lifts the soil out of the hole and it lands circling the hole. This soil isn’t in chunks the way you’d have backfill if you dug with a trowel. I found that a slow up-and-down motion helps to move that soil up and out of the hole. When you fill the hole after planting, the soil is in excellent shape for root growth. Or, instead of backfilling with the soil, fill the hole with a mix of compost and top soil to just below or even with the soil line. When you water, that ring of soil acts like a dam, containing the water so it has a chance to sink in rather than flow away.
Loosen soil in old containers. Sometimes you can get two growing crops out of the same container of soil or fabric growing bag. Remove the above-ground growth and then drill with the auger throughout the container to loosen root s and to help make the soil loose again.
