DHD1120 DTH Drill Bits for High Air Pressure
By using high-quality raw materials, utilizing advanced craft
technologies and imposing strict quality inspection, the product
range covers: down the hole hammers and bits(dth hammers and dth
bits), drill pipes, various size of threaded drilling bits, reverse
circulation hammers and bits, shank adapters and coupling sleeves,
drilling rig, air compressor and spare parts for drill equipment.
Down the hole hammers are connected with down the hole bits to do
the drilling works. New Diamond uses high quality steel and the
best level tungsten carbide as the raw material,with it's special
heating treatment technique and advanced carbide inserting
technique ,the bits perform well even on the hard rock formations
and save the energy to a maximum limit at the same time.
1, Button Shape: Spherical,Semi-ballistic,Ballistic.
2, Mainly used for Quarrying,Ore Mining,Coal Mining, soft, medium
hard, and hard rock,blast hole drilling and water well drilling
project,Marble quarry or well drilling and other construction
3, Our cemented carbide buttons have very good wear-resistant, can
be ground t·ime after time and have a longer service life. Using
the specially processed formula, our carbide buttons can meet
requirements of various rocks.
4, Buttons are strong in the mining process, and the service
lifetime is very long.A lot of grades can be chosen according to
5, Exactly suggestion for the button used for soft, medium-hard,
and hard rocks.
6, Durable performance, wear resistant and withstanding large
7, Very good prices according to market situation.
9, Very fast delivery time.
9, The best and reliable after-service.
It is mainly used in geological exploration, coal mine, water
conservancy and hydropower, highway, railway, bridge, construction
and so on.

1. Long life span: the wear-resist of tungsten carbides is 10-20
times higher compared with other similar materials, which greatly
extends the life of the carbide bits;
2. High drilling efficiency: the high grade hardness of the
carbides can always stay sharp, which could increase the drilling
3. New Diamond's bits are widely used in different rock formations
like carbonate rock,limestone,chalk rock, clay rock,siltstone and
4. It can greatly reduce the drilling cost, because of its high
drilling speed and life span, which reduces the times to changes
bits in the drilling service.
