Medium to hard ground formations are no problem for this DTH Hammer
Bit. The DTH bit keeps average hole straightness but drills at an
excellent speed.
3.

When percussion or hammer drilling your choice of hammer bit is
just as important as your choice of down hole hammer. DTH stands
for “down the hole”. When hammer drilling, the hammer bit gets its
energy from repetitive striking of a pneumatic down hole hammers
piston. This hammering with slow rotation drives the hammer bit
gradually through ground formations. DTH hammer bits are most
commonly used in percussion rotary air blast drilling, mining blast
holes, and mineral exploration and water well drilling industries.
The cutting interface of the DTH hammer bits are loaded with high
quality tungsten carbide, which is an extremely hard material.
Since hammer bits work with air pressure delivered to the down hole
hammer, it is important to use the recommended pressure provided
when hammer drilling. Down hole hammer bits come with a wide
variety of carbide styles. The sharper the point, the softer
formation it is used for. The different styles of carbides on the
hammer face include dome, cone and ballistic tungsten carbide
inserts which are press fit into the DTH bit.
Roschen can open up the flushing holes to provide hammer bits that can be used in reverse circulation drilling. Customized Hammer Bits, Flat Faced Hammer Bits, Convex Hammer Bits, Drop Center Hammer Bits, Concave Hammer Bits, and all kinds of exceptional custom drilling tools are offered at Roschen group limited.
