Welcome to the Digga blog

Digga’s range of screw anchor and auger drives are the ultimate in performance, quality and cost effectiveness. With over 30 years of design and development, working in the field and listening to the needs of our customers to exceed their expectations. All Digga drive units are manufactured in Australia, by Digga - from the hood on the drive to the gear box and Eaton motor. Our drives feature key design modifications to stand them apart from the competition: Integrated motor and output housing unit Our custom designed hydraulic motors were developed in conjunction with Eaton, using Eaton Geroler technology. Not satisfied with an off-the-shelf motor we developed the design specifically for the earth moving industry; significantly reducing the weight and overall length of the drive unit by integrating the hydraulic motor into the actual housing. Merging the motor with the input housing creates a direct connection to the gearset and eliminates the need for several gearbo...

It is said that the first recorded use of a screw pile was by Alexander Mitchell, a brick maker and engineer from Ireland who coined the term ‘screw-pile’ in 1833. Initially the concept of screw piling was used to provide solid foundations for lighthouses in soft soil and provided enough holding power to safely moor ships in the harbour. The original screw pile concept cannot be officially confirmed but in the April 1848 issue of the Civil Engineer and Architects Journal the article highlights the mechanics of the bearing power of screw moorings and screw piles which Alexander Mitchell is argued to have introduced:  "The origin of the screw-pile was the screw mooring, which was designed for the purpose of obtaining, for an especial purpose, a greater holding power than was possessed by either the ordinary pile or any of the usual mooring -anchor blocks, of however large dimensions.... whether this broad spiral flange, [or ’ground screw,’ as it may be termed] were fixed...

Having trouble drilling? The correct vertical alignment of your auger into the ground is essential to ensure efficient & effective drilling with your excavator. The natural arc movement of the boom causes the dipper arm to move out of alignment as it is raised or lowered, which is why constant operator adjustments are required to maintain vertical alignment. Please consider, that failure to do so will create significant side load on the auger drive and auger! As Digga auger drives are pendulum drills designed to hang freely from the excavator mount - excessive side load may result in bent auger flights, pipe and hubs as well as potential damage to the auger drive shaft, seals and gearbox. When you are drilling especially into hard ground this may also  cause socket and pilot breakage. So make sure to align your auger and drive correctly, to avoid damager and drill which much better performance. You can find more info and tips for drilling in harder grounds such as rock or...

Digga is as Aussie as the phonetically spelt name suggests. Solidified as our country’s leading machinery attachment manufacturer and exporter, the company still remains proudly Australian owned and operated. Let’s dig a little deeper into this national treasure as we salute a true blue Industry Leader. The company experienced extreme progression and growth in their first decade as their range of products steadily increased, including the manufacture of their own world-class gearboxes. While Stewart continued to build a strong team of expert professionals around him, he also improved Digga’s internal manufacturing processes with the introduction of computerised machining, robotic welding and more advanced steel cutting equipment to their assembly line. After establishing themselves in Australia, Digga began exporting their quality products and gaining a reputation overseas, firstly in New Zealand and Europe in 1997 and then in the US in ’99. In 2006 the company moved into their ow...
