5'' Hard Rock High Air Pressure Black Color DTH Hammer for Mining
Drilling
Product description
A down-the-hole hammer (DTH hammer) is a tool that can be attached
to the end of a drill string and inserted into a bore. It's a small
jack hammer used to break hard rock into small particles that can
be flushed away by the DTH hammer's air exhaust.
Product Advantages:
1. Valveless operation to maximize energy output, provide efficient
air utilitzation and reduce service requirements
2. Extra air-flow system allows for better hole cleaning in
troublesome holes
3. Reversible hardened wear sleeve for optimum wear resistance even
in the most abrasive conditions

Face shape Features
Drop Center
For high penetration rates in soft to medium hard and fissured rock
formations. Low to medium air pressures. Maximum hole deviation
control.
Concave Face
The all-round application bit face special for medium hard and
homogenerous rock formations. Good hole deviation control and good
flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to
medium air pressures. It is the most resistance to steel wash, and
may reduce the load and wear on the gauge buttons, but poor hole
deviation control.
Flat Face
This kind of face shape is suitable for very hard and abrasive rock
formations in applications with high air pressures. Good
penetration rates an resistance to steel wash.
Double Gauge Face
This kind of face shape is suitable for fast penetration rates in
medium to hard rock formations. Designed for high air pressures and
good resistance to steel wash step gauge bit.
Product application
At present, DTH drilling tool is widely used in underground mining,
quarries, hydraulic and Hydro-Power Engineering, water well
drilling, Mineral exploration, anchoring hole drilling, geothermal
engineering, Subway excavation, another civil engineering.
DTH is one of the most efficient ways of drilling rock, using a
rapid hammer action to break the rock into sizeable chips which are
then evacuated from the bore hole by the air exhausted from the DTH
Hammer. The technique provides fast drilling of accurately aligned,
straight and clean holes in most ground conditions.
