Schramm AirDrill 600 Series Reverse Circulation Hammers are manufactured to suit your drilling requirements in any terrain. Maximize your performance and efficiency with Schramm Hammers & Bits.

 

The AD600 Series has been comprehensively redesigned for maximum airflow, resulting in improved flushing at varying pressures. Each hammer is designed with minimal internal parts to avoid complications. With the advantage of a top loading inner tube, the time taken to replace worn components is greatly reduced compared to other hammer designs.
