DTH hammer is used for drilling holes through a wide range of rock types, the variety of which continues to extend well beyond the original conception of early blast hole drilling.
Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs.
Drilling Supply Store offers a wide range of DTH hammers suitable for a variety of drilling operations. Our Down the Hole hammers provide the most versatile and cost effective rock drilling method.
The DHD350 is a general purpose hammer suitable for all rock conditions at a wide range of air pressures. The hammer is fitted with a reversible cylinder to prolong the service life. Mach 50 is versatile and reliable, requiring only a few simple tools for servicing and maintenance.
This hammer is most suited for use with the Overburden system because of the high frequency of the piston/cycle.
Suitable for operation at air pressures of 100 - 350 psi (7 - 24 bar).
Drilling diameters of 127 mm - 165 mm (5 - 6 1/2").
Available Shanks: DHD 350
1. High hammer impact power and high drill hole efficiency.
2. The DHD Hammer is easy to disassemble and maintain.
3. There is no tail pipe (nylon pipe) in the bit, in order to eliminate the thermal expansion, cold shrinkage and damage of the bit in operation.
