DTH Hammers

The "Down-the-hole" or 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.

MACH 120

The Mach 120 accepts A100-15 (SD12) shank bits and has a working pressure range of 170 - 350 psi (12 - 24 bar) whilst its optimum performance is reached at air pressures of 200 psi (14 bar) and above.

MACH 122

The Mach 122 accepts A100-15 (SD12) shank bits and drills most effiently at air pressures between 100 psi (7 bar) and 170 psi (14 bar), due to its higher air consumption, provides increased uphole velocity, particularly when using oversized diameter drill bits.

MACH 132

The Mach 132 hammer accepts IR DHD112 shank bits. This hammer, although capable of high pressure drilling is particularly suitable at pressures between 7 - 14 bar (100-200 psi).

MACH 142

The Mach 142 hammer accepts IR DHD112S shank bits.and is equipped with an oversize chuck to drill larger diameters at air pressures between 7-24 bar (100-350 psi). This oversize chuck protects the cylinder and prolongs its life. This hammer has a pin drive arrangement to prevent spline to spline contact therby minimising spline wear and damage which can result in bit shank failure.

SUPER DOMINATOR 1200

The Super Dominator 1200 accepts QL 120 shank bits and drills most effeciently at air pressures between 100psi (7 bar) and 170 psi (14bar), due to its higher air consumption, provides increased uphole velocity, particularly when using oversized diameter drill bits.
