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.
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.
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.
The appearance of the picture is different from that of the actual
product, and the actual product is the standard.
