Product Description

CIR90 DTH Hammers and Button Bits Down The Hole Hammer for Quarry Drilling

CIR90 DTH Hammers and Button Bits

 

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.
 

Roschen 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.
 

Advantages:

1. Valveless air distribution. More reliable.

2. Simple design of the piston, long life.

3. More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.

4. Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated.

5. It is easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi step thread.
