Product Introduction
Our drilling bits are widely used in different drilling applications including mining,quarrying, water well drilling, geotechnical industries and etc.
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.

Detailed photos:
DTH Drill Bits can be divided into the following three types according to their appearance:
1. Flat type: suitable for drilling hard rock layers and highly corrosive rock layers under high wind pressure.
2. Convex type: suitable for drilling soft to medium hard rocks with medium to low wind pressure, with fast drilling speed.
3. Concave type: suitable for all rock layers, especially in medium hard rocks, with good drilling straightness and slag removal effect.
