Our Alloy Steel DTH Drill Bits are made of high quality alloy steel with advanced heat threatment to assure the good drilling performance and long service life. They are widely used by our customers all over the world.The DTH bits have various sizes and styles ,For the most effective operation in various drilling conditions, we offer flat face, concave, drop centre head designs.
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.

Feature Advantage
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 speeds too;
3. New Diamond's bits are widely used in different rock formations like carbonate rock,limestone,chalk rock, clay rock,siltstone and sandstone;
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.
