Excessive Wear on Rock Augers

Image
Customers often ask us about excessive wear on rock augers. As rock augers are designed to drill through very tough ground and hard rock, we’d like to outline what kind of wear should be expected, why rock augers wear and how this can be avoided to keep your augers operating at maximum performance. First of all, what types of rock augers are there? At Digga we offer three variations of rock augers. The Digga Earth/Rock Combo Rock Auger features tapered tungsten taperloc teeth and is designed for drilling in earth, shale, permafrost and some fracturable rock. Dedicated Rock Augers on the other hand, come in a standard and Tapered Rock variation, both featuring rotating picks and used to drill in fracturable to hard rock. The design with short flighting and rotating pick pilot encourages regular spoil removal, allowing cool air to enter the hole, and facilitate regular tooth inspection. Additionally, a hard-faced finish is applied to the flight edges and pockets of the dedicate...

Continuous Flight Augers with Removable Cutting Heads

We recently delivered a custom drilling solution for one of our customers, who uses a piling process called Sheet Piling. For this particular application, Digga developed and provided CFA style augers with a removable cutting-head-design and varying lengths.   What are traditional CFA augers? Here is some background information: Continuous Flight Augers (CFA) are mainly used for drilling water-bearing sandy soil, sludge, clay, muddy sub clay, sandy gravel, cobble, and weathered soft to hard formation (rock).  CFA piles are a type of drilled foundation in which the pile is drilled to a final depth in one continuous process, using a continuous flighted auger (CFA). Concrete or grout is then pumped under pressure down the hollow stem of the auger to the bottom of the bore. Once pumping starts the auger is progressively withdrawn bringing the soil with it to the surface, leaving the Concrete/Grout in the pile. Reinforcement (Reo) is then added to the concrete p...
