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.
