Digga Tips - Which Auger to Choose for What Ground Conditions
When drilling in different ground conditions you need the right speed and the right cutting system on the auger to suit the different ground conditions. So which auger should you choose for your application?For efficient drilling on any machine requires power (torque) and down pressure. Digga augers perform better at an optimal RPM against the ground conditions they are against. Similarly the auger diameter will perform better at certain speeds. For example: the larger the hole and harder the ground conditions, the slower you will need to drill. The smaller the hole and softer the ground conditions, then more speed is required. As a general rule we recommend the following RPM/speeds: 55-65 RPM for general earth conditions. 45-55 RPM when drilling in heavy earth, clay or shale. 20-45 RPM when drilling in rock. Results will depend on rock hardness, type of auger being used and machine down force. Digga recommends the following for attachments for the different ground c...
