Description
The Digga A4 450mm Auger Bit is a genuine earth auger bit designed for 1-5 tonne class excavators fitted with a compatible Digga drive hub. It bores clean, straight holes suited to larger footing holes, stump removal prep and heavier landscaping work. Unlike an auger drive unit, the bit itself requires no hydraulic supply — it is driven by the auger drive it is fitted to.
