Air Core

When customers think Air Core they think Brown Bros Drilling. We have a rich experience in Air Core Drilling dating from the mid 1980's. Only brand named Australian Factory pipe and tooling is employed, resulting in a quality sample, less down-hole issues, and more holes in the ground.

Some of the geology Brown Bros Drilling has Air Cored include: mineral sand, coal, aggregate sand and pumice, and soft limestone.

You will be impressed by the drilling speed and sample quality.

  • 75mm Air Core is the most common size (we also offer an 89.00mm & 114.30mm diameter)
  • From vertical to 45 degree angle holes
  • Hole depths of up to 100 metres possible on 75mm size
  • 75mm Reverse Circulation Down-Hole Hammer can also be used on this drill system – Air Core the top R.C the bottom
