All tooth bit series passivation cycle is long, the wear life of about with the blade diameter titles bit wear life of 5-6 times, can save auxiliary worKing hours, reduce the physical labor of workers and accelerating the pace of work. Therefore different diameter of the taper connection and thread connection ball tooth bit is widely used in all kinds of hard and brittle rock with the drilling rig. Sweden's engineering and technical personnel that ball tooth bit and hydraulic drilling jumbo combination, is the best matching of modern drilling technology.

In the recent 20 years, Thread Button Bit series development very fast, it is accompanied by hydraulic rock drill hole quickly save industry to improve the drilling speed and drilling auxiliary working hours.

Compared with the traditional sheet bit, Column tooth drill bit with the advantage of grinding cycle length, drilling speed.
