Mach 120 Mach 122 Mach 132 DTH Hammer

12” Mach 120

Mach 120 has a working pressure range of 170-350psi(12-24bar) whilst its optimum performance is reached at air pressures of 200psi(14Bar) and above.

Mach 120 has no liner which increases the 140kg piston’s blow energy and reduces parts required.

12” Mach 122

The Mach 122 accepts A100-15(SD12) shank bits and works over a wide pressure range with and optimum performance reached at air pressures of 200psi(14bar) and above as its higher air consumption provides increased up hole velocity, particularly when using oversized diameter drill bits.

Mach 122 has a one piece top-adaptor with N.R.V fitted for easy inspection and service, with integral finger to reduce maintenance and eliminate shimming which increases service intervals. Servicing requires only a few simple tools. Mach 122 has no liner which increases the 140kg piston blow energy and reduces parts required. This hammer is suitable for use with overburden systems.

12” Mach 132

The Mach 132 hammer accepts IR DHD112 shank bits, This hammer, although capable of high pressure drilling is particularly suitable at pressure between 100-200psi(7-14bar).

The Mach 132 has a pin drive system to prevent metal to metal contact thereby minimizing spline wear and damage which can result in drill bit shank failure.

Mach 132 has a one piece top-adaptor with N.R.V(Non-return-valve) fitted for easy inspection and service, with integral finger to reduce maintenance and eliminate shimming which increases service intervals. Servicing requires only a few simple tools. Mach 132 has no liner which increases the 140kg piston blow energy and reduces parts required. This hammer is suitable for use with overburden systems.
