Alloy Steel ND55 DTH Drill Bits
DTH bit is our company main product. After mang years search, we
have rich experience in development and manufacture which adopted
high-quality raw materials, advanced craft technology and passed
through strictly inspection, manufacturing high quality products.
All our products are widely used in mining, water well
drilling,tunneling, quarrying, construction, and civil engineering
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.

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.
