Product Details

Progressive Blow Energy

The unique design of the piston generates a perfect, long shock wave of a trapezoidal shape:

better transmission of energy at the couplings

minimum stress into the drilling rods

better bit penetration

Hydraulic Dampening System

This technology is the reason why Montabert’s hydraulic drifters have a long operational lifespan. The action of the dampening

piston, not only absorbs the lost part of reflected energy but ensure a constant, thrust onto the tools:

Optimum shock wave transmission

Protection of the hydraulic drifter and tools

Reduced vibrationsHydraulic Reverse Percussion

Energy Recovery Valve

This valve allows the piston rebound energy to be utilized for the next blow, giving a definite advantage to the HC series of

hydraulic drifters:

Better efficiency

No internal peak of pressure source of cavitation

Best drifter protection

Hydraulic Reverse Percussion

The optional hydraulic reverse percussion system insure a real back hammering:

Tool extraction in fractured ground

No rods left in the hole
