Digga A4 300mm Rock Auger Bit – Tungsten Teeth for 1-5T Excavators

Description

The Digga A4 300mm Rock Auger Bit is engineered specifically for drilling into shale, fractured rock, and other hard ground conditions that would stop a standard soil auger in its tracks. Heavy-duty tungsten short-style teeth are positioned for maximum penetration, biting into rock and breaking it up efficiently as the auger rotates, rather than simply grinding against the surface. This 300mm diameter bit is a key tool for Australian retaining wall builders, fencing contractors, and civil crews who need to bore consistent, clean holes for posts and footings even when the ground includes rocky or shale layers. Fitted with a standard 65mm round hub, the A4 rock auger is compatible with the wide range of Digga and equivalent drive units already common across 1 to 5 tonne excavators in Australia. Genuine Digga engineering means the flighting and boss are built to handle the torque loading and abrasive wear that comes with rock drilling, extending service life compared to lighter-duty soil augers pushed beyond their intended use. Retaining wall installers boring footing holes through rocky hillsides, fencing contractors working on rural properties, and civil contractors preparing sign or post foundations all depend on this auger bit to get through difficult ground without constantly swapping equipment. Backed by a 12 month warranty and manufactured in Australia, the Digga A4 300mm Rock Auger Bit is available brand new for fast delivery nationwide.
