6 Inch High Pressure Down The Hole Drill Bit For DTH And Water well drilling
Application
What are ‘Down-the-Hole’ (DTH) Drill Bits and how are they used?
Down-the-hole drill bits are used with down-the-hole hammers for
drilling holes through a wide range of rock types.
In conjunction with our DTH hammers, our drill bits are designed
with a splined drive for rotating the bit in the ground. Drill bits
are available in a range of different sizes and configurations so
they can drill a wide range of holes sizes, in different ground
conditions.
How have DTH Drill Bits developed?
Down-the-hole drill bits are used with down-the-hole hammers for
drilling holes through a wide range of rock types.
In conjunction with our DTH hammers, our drill bits are designed
with a splined drive for rotating the bit in the ground. Drill bits
are available in a range of different sizes and configurations so
they can drill a wide range of holes sizes, in different ground
conditions.
Rapid advances in drill bit technology have occurred throughout the
last 40 years. The first type of drill bits used with down-the-
hole hammers were ‘cross bit’ design. Four chisel shaped lengths of
tungsten carbide were brazed creating stresses within the drill bit
thereby limiting its life. A further disadvantage of the cross bit
design was that the majority of the carbide was situated around the
centre of the bit face and not towards the outer edge of the drill
bit where there is the most rock to cut.
In the late 1960s however, the button bit was introduced; this was
a landmark in the progress of DTH equipment, which led to bit lives
previously unheard of.
Cylindrical button inserts were precision ground to extremely close
tolerances and pressed into the bit as an interference fit. This
resulted in improved carbide insert retention by eliminating
brazing stresses and other defects associated with brazing and
braze materials.
Buttons inserts are distributed more efficiently than cross bit
inserts by providing more cutting power where it is needed at the
outer edge of the drill bit face.
In many cases, the need to sharpen the drill bit was eliminated
with the arrival of the button bit and the improved cutting action
provided While the cross bit design is still used in some rotary
and drifted applications where the rock is very soft, the button
bit is now used in virtually every DTH application.
