The Mach 122 accepts A100-15 (SD12) shank bits and works over a wide pressure range with an optimum performance reached at air pressures of 200 psi (14 bar) and above as its higher air consumption provides increased uphole velocity, particularly when using oversized diameter drill bits.
Mach 122 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. Mach 122 has no liner which increases the 140 kg
piston blow energy and reduces parts required. This hammer is suitable for use with overburden systems.
Suitable for operation at air pressures of 100 - 435 psi (7 - 30 bar).
Drilling diameters of 300 - 445 mm (11 7/8 - 17 1/2").
Available Shanks: Sandvik Mission A100-15/SD12.
