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 inch 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 (7 - 24 bar).
Drilling diameters of 85 - 100 mm (3 3/8 - 4").
Available Shanks: Halco Mach 303.
