Core Barrels

Core Barrels are used when conventional augers are less effective or in conjuction with tapered rock augers for very hard rock drilling. The Core Barrel is designed with a thin cutting edge to maximise the penetration rate through less contact surface area having to be cut and removed.

Digga Core Barrels range from 300mm - 2000mm in diameter and come fitted with a Kelly Box (drive hub) to suit your machine.

  • Provision for reamer bars
  • Standard (STD) & heavy duty (HD) base ring option available
  • Comes fitted with Kelly Box (drive hub) to suit your machine
  • Wear ribs extend barrel life and eliminates barrel stalling
  • Custom Buckets & other tooth options available upon request
