Augers for Mini Excavators 3-5t

Digga's range of drilling augers for 3 ton to 5 ton Excavators are the ultimate in performance, quality and cost effectiveness. Over 30 years of design and development has produced the highest quality range of auger drives on the market today. Completely manufactured and assembled by Digga, using only the highest grade materials and strictest quality control.

Fitted with Digga / Eaton bell motorss with intergrated pressure relief valve and input housing. The innovative design allows the gearbox to go down the hole to maximise drilling depth without extentions, eliminating downtime and minimises maintenance, optimizing your returns.

Digga drilling augers are backed by industry leading warranty and local factory support.

Digga's new Halo Alignment System is the future of drilling. Located on the hood of the ring on the Drilling Drive, the Halo Alignment system eliminates the need for any spotter & ensures all holes drilled are plumb.

Digga planetary augers are specially designed for Excavators for drilling and augering in most ground conditions. The addition of our patented "Energy Control Valve" turns the drilling drive into a screw anchor drive.
