  12" Mach 120 cutaway

12" - Mach 122

Available Shank: Sandvik Mission A100-15/SD12

The Mach 122 accepts A100-15 (SD12) shank bits, and its optimum performance is reached at air pressures of 200 psi and above. The Mach 120 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 309 lb. piston’s 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.
Drilling diameters of 11 7/8 - 17 1/2".
