Top Choice｜A4 Earth Auger Bits｜ Other Products

Digga's range of Auger bits is designed with the ultimate in performance, quality and cost effectiveness in mind.
With the A4 range, you benefit from its hex drive pilot over the square drive - giving machines with higher down pressure and higher torque greater strength. The A4 suits Skid Steers and Excavators up to 4.5 ton for drilling in earth.
The A4 is a flat tooth auger bit with chisel ripping teeth on inner pockets. Ideal for general earth & clay drilling. With multi facet tungsten teeth fitted, granulated and soft fractural rock conditions can be drilled.
This auger bit has been designed with a double start single carry flight configuration. Its flight pitch is shallow for greater soil retention, and its heavy-duty body allows for greater reliability in tough conditions.
Can't get your old teeth out? Digga's ingenious knock in, knock out tooth locking systems eliminate the need for cumbersome tools to remove the auger teeth.
