An auger can appear to be a relatively simple attachment: a tool rotates, enters the ground and removes material. In practice, however, effective drilling requires Digga augers, their hydraulic drive and the carrier machine to operate as a properly matched system.
A mini excavator, skid steer and larger excavator do not provide identical hydraulic capabilities. Selecting an auger system should therefore begin with the machine that will supply the power required for drilling.
What does hydraulic flow do?
Hydraulic flow essentially describes the amount of fluid the system can move during a given period.
Within an auger system, flow influences how quickly the drive can operate.
Two machines that appear relatively similar can provide different hydraulic flow rates.
This is why knowing that an auger will be installed on a “mini excavator” is not enough. The exact machine model provides much more useful information when determining what the equipment can operate correctly.
Pressure and torque are not the same thing
Hydraulic pressure contributes to the system’s ability to produce force.
Torque describes the rotational force available at the auger.
As ground becomes more difficult to penetrate, available torque can become increasingly important.
Rotating an auger quickly does not automatically mean that it will have the force required when significant resistance is encountered.
This is why selecting Digga augers involves more than simply considering rotational speed.
Start with your machine specifications
Before choosing an auger or drive, gather the technical information for your carrier.
Exact model, available hydraulic flow, system pressure and mounting configuration provide an excellent starting point.
Then add the requirements of the work itself:
required hole diameter, expected drilling depth, ground conditions and how frequently the auger will be used.
With these details available, the system can be considered as a complete combination.
A larger auger or more powerful drive provides little benefit if the carrier cannot supply the hydraulic characteristics needed to operate it.
Earth and rock require different tools
Even with a perfectly matched hydraulic system, ground conditions remain essential.
Relatively soft soil can be drilled with a different configuration than highly compacted ground or rock.
The teeth and components at the leading end of the auger directly contact the material being drilled. Their design therefore influences how effectively the auger penetrates the ground.
Before selecting equipment, determine whether the work will primarily involve soil, clay, gravel or more challenging rocky conditions.
This information can be just as important as machine power.

Consider diameter and depth together
Diameter is easy to visualize because it directly corresponds to the width of the required hole.
Depth can sometimes receive less attention even though it also affects system configuration.
Some projects require only a few feet of drilling while others need to reach considerably deeper.
Depending on the application, extensions or a different setup may be necessary.
Defining both measurements before shopping can therefore make the selection process much easier.
A properly matched system supports productivity
A carrier, drive and auger that are properly matched give the operator a system suited to the work rather than forcing the equipment to constantly operate around its limitations.
This can make drilling more predictable and help avoid selecting a combination that is unnecessarily oversized or unable to handle the intended application.
