Welcome to the Digga blog

Digga's dedicated rock augers (DR) require constant maintenance to remain effective. The teeth must be free to rotate inside the pocket. Teeth that stop rotating will be inefficient and wear out faster causing damage to the tooth pockets and flights. In the video below, Queensland Sales Manager Anthony Wieckmann talks to you in detail about our dedicated rock augers – the tool you need if you’re drilling into hard fracturable grounds. Tips when drilling in rock When drilling in rock for extended periods of time air is trapped in the hole creating an “oven”. This can cause the face of the rock to glaze over and become even harder. For this reason, you should stop drilling and allow fresh air back in the hole approximately every 5 minutes. As you stop drilling, bring the auger to the surface and allow fresh air back down the hole. Remove any spoil from the auger and inspect the teeth and pilot for wear and that they can turn freely in their pocket. For more informat...

The right auger for the right ground condition is key to working productively. Here we have a brief overview of the 3 different 'standard' auger ranges Digga manufacture. 'A' or 'earth' range of augers Digga's A augers are efficient in cutting through earth, clay and soft ground as it uses flat teeth to peel up the layers. Our A augers have 3 teeth options within the range to aid wear; the standard earth tooth, flat carbide tooth or raised carbide tooth option.  'RC' or 'rock combo' augers Digga's RC range of augers uses a tapered tooth which can be used on rocky/ earthy grounds. The tungsten tipped teeth helps to rip into the ground.  'DR' or 'rock' augers Dedicated rock augers are ideal for bursting into material such as shale or rock. They use a pick tooth to break and fracture into the ground.  Watch our video of Anthony giving a brief overview of the range here:  ...
