Mach 20 DTH Hammer and Mach 44 DTH Hammer
2inch Mach 20
The valved design of the Mach 20 provides high performance at low pressure. A non -return valve is fitted to prevent flooding when drilling in water.
The Mach 20 has a strong robust design to withstand heavy duty applications. The Mach 20 is fitted with adjustable chokes to give three levels of air volumes for different drilling conditions. The unique drill bit design for Mach 20 does not use foot valve which reduces the possibility of hammer failure.
Mach 20 shank has a long service life reduces contact stresses and wear rates.
Suitable for operation at air pressures of 100-250psi(7-17bar). Drilling diameters of 70-76mm(2 3/4-3”).
