Digga Heavy Duty Core Barrel 400mm | 16–20 Ton Excavators | From $5,390 Inc GST
Australian Made Heavy Duty Core Barrel for Hard Rock Drilling Applications
The Digga Heavy Duty Core Barrel is designed for drilling applications where conventional augers become ineffective or when used in conjunction with tapered rock augers for extremely hard rock drilling conditions. The Core Barrel features a thin cutting edge designed to maximise penetration rates by reducing the amount of contact surface area that must be cut and removed during drilling.
