High Air Pressure Cop 32 DTH Hammer and Button Bit for Water Well
Drilling
DOWN THE HOLE DRILLING HAMMERS
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.
Made with high quality of raw material through special heat
treatment, especially, tungsten carbide of tapered button bits are
from Boart long year, widely applied in Hand Hold ( short-hole)
drilling system for dimensional stone quarrying. At now, we are
exporting the huge qty of Q7- 33- 7 22-80, Q9 -45 -12 22- 71 for
Indian quarry and Norway, Finland quarry.
Diameter of bits from 30mm to 50mm with 4, 6, 7, 11, 12 degree,
premium alloy tapered drill steel with Hexagonal. 22mm and
Hexagonal. 25mm, The deliver capacity are very strong and can
completely meet customer's requirements on delivery design, number
of buttons is 4, 5, 6, 7, 8, 9, 7 buttons is very popular for hold
held (short holes ) and blast drilling system.
