Choosing the Right Mini Excavator Auger For Your Job in 2023

Choosing the Right Mini Excavator Auger For Your Job

A mini excavator auger is an attachment designed for use with a mini excavator. It is a drilling tool used to dig holes in the ground for various applications, such as fence posts, landscaping, and construction projects. The auger consists of a drill bit, a drive unit, and a mounting bracket that attaches to the mini excavator.

The excavator’s hydraulic system power the mini excavator auger with hydraulic pressure. The operator can control the speed and direction of the auger using the excavator’s controls. So you can make it a versatile and efficient tool for digging holes. Mini excavator augers come in different sizes and configurations to suit different digging applications.

They can use to dig holes of various diameters and depths and are fitted with different drill bits, such as rock bits or auger bits with teeth for digging through tough soil. When using a mini excavator auger, you should follow proper safety procedures, and using the appropriate protective equipment is essential. The safety gear involves wearing gloves, eye protection, and hearing protection and ensuring the area around the excavation site is clear of obstacles and other hazards.

Premier Attachment offers standard and heavy types of Mini Excavator auger drives. The Standard Duty auger drive, our most affordable, is designed for light to moderate drilling conditions. The Heavy-Duty auger drives are built with industrial-grade components for the most challenging drilling conditions. 

 Types of Mini excavator auger

Mini excavator augers are used for drilling holes in different types of soil and terrain. Every type is for specific applications and soil conditions. 

Standard Duty Augers: 

Standard duty augers are designed for general-purpose digging in loose to moderately compact soils. They have a single-flight design and are available in different diameters ranging from 4 to 36 inches. Standard duty augers can be used for various applications, including fencing, landscaping, and foundation work.

Standard Duty Augers: 

Heavy Duty Augers: 

Heavy-duty augers come for more demanding drilling applications, such as digging through hard soil, clay, and rock. They have a double-flight design and can produce higher torque and speed than standard duty augers. Heavy-duty augers are available in larger diameters ranging from 6 to 48 inches and can be used for applications such as drilling pier holes and footings.

Standard Duty Augers: 

High Flow/High Torque Augers: 

High flow/high torque augers are designed for the most demanding drilling applications, such as drilling through hard rock or frozen ground. They have a double-flight design and can produce high torque and speed. High-flow/high torque augers require a high-flow hydraulic system and are available in larger diameters ranging from 8 to 48 inches.

Auger Bits:

Auger bits are used with standard duty augers and come in different shapes and sizes, depending on the soil type and drilling application. Bullet teeth are used for digging in soft soil, while chisel teeth are used for digging in harder soil and rock. Auger bits are available in diameters ranging from 4 inches to 36 inches.

Auger Bits:

Auger Extensions: 

Auger extensions are used to extend the length of the auger and can add to both standard-duty and heavy-duty augers. They are available in various lengths, ranging from 12 to 48 inches, and can be combined to reach greater depths.

Auger Drives: 

Auger drives are hydraulic attachments that are used to power the auger. They are available in different sizes and configurations, depending on the size and weight of the auger and the hydraulic system of the mini excavator.

How to use Mini Excavator Auger safely

How to use Mini Excavator Auger safely
  1. Read the operator’s manual: Before operating a mini excavator auger, carefully read the operator’s manual to understand the operating procedures and safety guidelines.
  2. Check the equipment: Inspect the auger and mini excavator before use to ensure that all parts are in good working condition. Check for any signs of damage or wear, and replace damaged parts.
  3. Use proper PPE: Always wear the appropriate personal protective equipment (PPE), including safety glasses, gloves, and steel-toed boots, when operating a mini excavator auger.
  4. Use the right drill for the soil type: Choose the appropriate auger for the type you will be drilling. Using the wrong type of auger can cause damage to the equipment and create safety hazards.
  5. Position the mini excavator safely on a level surface and ensure stability before operating the auger.
  6. Keep bystanders away: Ensure that there are no bystanders or obstacles within the swing radius of the mini excavator. Keep a safe distance from the drilling area.
  7. Use the controls properly: Operate the mini excavator auger controls smoothly and carefully. Do not jerk or force the controls, as this can cause the equipment to tip over or malfunction.
  8. Avoid overloading the auger: Do not use excessive force or weight. This can damage the equipment and create safety hazards.
  9. Use caution when drilling near underground utilities: When drilling near underground utilities, avoid damaging them.
  10. Shut down the equipment properly: When finished using the mini excavator auger, shut down the equipment properly and securely store it.

How to buy a best mini excavator auger

Determine the soil type:

 The type of soil you want to drill through will impact the type of auger you need. Standard-duty augers are designed for loose to moderately compact soils, while heavy-duty and high flow/high torque augers are better suited for hard soils and rock.

Determine the soil type:

Determine the hole diameter: 

The hole diameter you need to drill will determine the size of the auger you need. Augers are available in various diameters ranging from 4 inches to 48 inches.

Determine the soil type

Determine the depth of the hole:

 The hole depth you need to drill will determine the length of the auger you need. Auger extensions can add to extend the length of the auger, but ensure that the auger and extensions are compatible with your mini excavator’s hydraulic system.

Check compatibility: 

It’s essential to consider that the auger and auger drive you choose are compatible with your mini excavator’s hydraulic system. Check the flow and pressure requirements of the auger and compare them to the specifications of your mini excavator.

Consider the price: 

The price of mini excavator augers can vary widely depending on the size, type, brand, and, most importantly, your budget. Compare prices from different vendors and factor in the cost of any necessary extensions or attachments.


Mini excavator augers are versatile and essential tools for drilling holes in various soil conditions and terrains. Choosing the right auger for your needs and soil conditions can maximize efficiency and productivity while minimizing downtime and equipment damage. You can contact us for more information.
