Air core bits |
|
 |
The dynamo of the air core industry. Available in 3", 3 1/2", 4" and 4 1/2" sizings. Choose between 3 and 4 blade configurations and a wide range of thread types. These extraordinarily robust bits feature extra heavy-duty tungsten carbide blades giving you the ability to withstand the penetration shocks of high speed air core drilling. The blade design balances cutting power with an open bit face to maximize drilling rates. These bits perform powerfully in a broad range of air core drilling conditions giving you more metres drilled per day in almost all situations. |
Vacuum Bits |
|
 |
The powerhouse bit for cutting ability and hard band penetration configured as a vacuum bit. You can use this bit to overcome face discharge drilling problems such as air loss in loose sands or fractured clays. The heavy-duty tungsten carbide blade design will maximize cutting ability and durability to lift productivity.
