Our Mission : Better solution and Lower cost

Our Vision : Trust and Reliabity,

Our drills are made from the best steels and alloys in the country. Japan or Germany CNC lathe thread and drilling alloy perforations to ensure the accuracy of the ball tooth bit. Advanced thermal inlay technology ensures that the quality of each ball bit is stable.

The ball tooth bit uses different alloy teeth (hemispherical teeth, bullet teeth, parabolic teeth, etc.) according to different rock formation structures and hardness. We can make alloy ball tooth drills of different specifications and different forms according to different needs of users. Widely used in mining, tunneling, underground plant excavation and other construction sites. It is an ideal substitute for the same type of ball tooth bit in foreign countries, with stable quality and high cost performance.
