Why choose a 2-speed drive over a single speed drive?

Digga Australia - 2 speed auger drive - Australian Made
If you’re working with multiple sized augers or often in different ground conditions you’ll understand the expense and time wasted that comes with needing multiple drive units for the different applications.

When the ground is soft you want a higher speed to get the hole drilled quickly and then move onto the next one. When the ground is hard or you’re using a large auger you need torque to get the job done efficiently.

Speed and torque are always a trade-off; when you increase your speed you lose power and when you increase your power, you lose speed. Similar to a manual car, fourth gear allows speed but struggles with the power required to get the vehicle up the hill…

Standard, single speed drives are typically manufactured as a cost effective solution to provide a speed and torque to suit most applications but will give you one or the other.

In recent months we’ve seen our 2 speed auger drives grow in popularity and, as leading manufacturers, we can understand why.

We understand that for our customers time is money and so, our range of 2 speed drive units have been designed to help you work more efficiently; providing you one drive to operate in all conditions.

The two speed drive is ideal for anyone who drills in a variety of different ground conditions and with a range of different diameter augers.

As the name suggests, two speed drives have two speeds in one unit:
  • Low-speed high-torque setting and,
  • High-speed low-torque setting

The Digga 2 speed drive units give operators the option to switch between power and speed. Rather than needing 2 drives (1 for smaller diameter augers and softer grounds and 1 for larger diameter augers and harder grounds), the Digga 2 speed drive unit gives operators both functionalities in one drive.

Features and benefits of the Digga 2 speed drive range

There are a number of key features and benefits of a 2 speed drive over the standard single speed, such as:

  • Save time and money by eliminating the need for multiple drive units
  • 2 speed drives are made with Eaton motors and Digga made gearboxes. The electrical plugs are high quality waterproof "Deutsch" connectors offer superior corrosion protection and waterproof properties.
  • 2 speed drives allow for quicker drilling with a small auger and in soft grounds, and more torque for drilling with a large auger or in hard ground.
  • Switch to high speed for faster spinoff of spoil on a high torque drive
  • The low speed / high torque setting is ideal for drilling in fracturable rock; higher RPMs in rock cause the teeth to “skate” over the rock making it glaze over and become harder.
  • The host machine can run at a lower engine RPM on certain drilling jobs therefore burning less fuel
  • With the same gearbox as a single speed drive, it is the same cost to service as a single speed drive unit.
  • By drilling quicker, the job is finished faster so you can move onto the next job
  • It’s important to remember that single speed drive units have suited the market for over 30 years and unless you are working with multiple-sized augers, in different ground conditions regularly a single speed drive unit remains a very adequate option.
