COP84 High Air Pressure DTH Drill Bits Quarrying Usage With Concave / Convex Face
Hunan New Diamond offers top quality DTH hammers and bits which have been tested in the hardest rock formation. Our bits use quality hardened steel alloy for the bit body and premium quality tungsten carbide buttons. With superb performance and long life span. Our bits won high reputation among our customers.
1. Button Shape: Spherical,Semi-ballistic,Ballistic.
2. Durable performance, wear resistant and withstanding large impacting force.
3. Long life span.
5. Fast delivery time.
Bit face shape selection:
1. Flat Face
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressure. Good penetration rates an resistance to steel wash.
2. Concave Face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
3. 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.
4. Center Drop Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressure. Maxium hole deviation control.
It is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.

|WE can design and manufacture according to customers requirement of the bit diameter,the NO.of air holes,carbide buttons and the face shape.|
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.
