General characteristics

The 2” and 2”1/2 are both valved type hammers designed for high performance at low operating air pressures. Simplicity of design, ease of service and low air consumption are all factors which combine to make these hammers robust and reliable drilling tools. Both hammers are available as standard with box thread, Rd 40 for the 2” and

Rd 50 for the 2”1/2. However alternative backhead options are available on request. The 2” and 2”1/2 hammers both incorporate a positive fitting check valve to guard against the ingress of ground water debris when the air is shut off.
