RC Drilling can be hard on air core bits so that’s the way we make them – Hard! Harlsan Air Core Bits for RC drilling are extremely robust and feature heavy-duty tungsten carbide blades. They are built for cutting ability and hard band penetration and to withstand the shocks of high speed air core drilling. The blade design balances cutting power with an open bit face that performs powerfully in a broad range of conditions.
Harlsan Vacuum Bits are ideal to overcome face discharge drilling problems such as air loss in loose sands or fractured clays.
“I’ve used Harlsan Air Core Bits for 15 years. The tungsten’s survive in ground where other bits fail and I can rely on Harlsan for modifications to suit any drilling conditions.”
Eric Brown, Owner – Goldfire Drilling
