3" - Mach 303
Available Shank: Halco Mach 303
Mach 303 is a general purpose hammer for small hole drilling used in applications such as seismic, geological survey, micro-piling, floor, wall and roof-bolting, or for blast-holes where environmental considerations limit hole size and blasting procedures.
The Mach 303 uses less air than most other 3" hammers in its range, which allows you to use a smaller compressor and gain in economy. The hammer is suitable for drilling at a wide range of air pressures in both soft and hard rock conditions.
Suitable for operation at air pressures of 100 - 350 psi.
Drilling diameters of 3 3/8" - 4".
