Description

DTH drill bit with drilling performance is stable, easy to use grinding, and the price is reasonable and other factors by the user. Now high-pressure down-hole drilling, the current design of the face there are four main forms: the convex surface type, the end surface of the plane, the surface of the concave surface and the end of deep concave center. Carbide multi-choice ball, spring or ball and tooth teeth common to the cloth teeth. Drill alloy can be divided according to the shape of hemispherical teeth, tapered teeth, parabolic teeth and other types. Hemispherical teeth with high load capacity, good wear resistance, suitable for drilling hard, hard and abrasive rock; tapered teeth and parabolic teeth drilling speed, suitable for drilling hard and non-abrasive rocks. DTH drill bits can also be used with the teeth (gage, drilling teeth) with the ball, the core teeth (broken broken rock) with tapered teeth, parabolic teeth in the form of compound cloth teeth, can reach under a variety of types of rocks quickly The purpose of drilling.

Applications


It is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.

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.
