Description

DTH drilling rigs are widely used in the large-aperture open-hole rock drilling project. DTH drill bit with drilling performance is stable, easy to use grinding, and the price is reasonable and other factors by the user. At present, most of the DTH drill bits adopt the ball-type alloy head and the spline-shaped tail handle. 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.
