What is a column tooth bit
The ball tooth drill bit is composed of hard alloy column teeth inlaid on the drill bit body. Compared with the chip bit, the ball tooth bit is free, and the number and position of the side and middle teeth can be reasonably determined according to the diameter of the drilling hole and the size of the rock breaking load, and the diameter of the bit is not limited. And because of its multi-point crushing, the efficiency of rock breaking is higher, which can not only effectively eliminate the blind area of rock breaking, but also avoid the repeated crushing of rock chips. In addition, because the abrasion of the alloy column is higher than that of the flake bit, its non-grinding life is longer, and the re-grinding workload is small, which shows high value under the operating conditions of mechanized rock drilling jumbo and deep hole mining.

The ball tooth drill bit is composed of hard alloy column teeth inlaid on the drill bit body. Relative to the chip bit,Ball tooth drill bit cloth tooth free,According to the drilling hole diameter and rock breaking load size,Reasonably determine the number and position of side and middle teeth,The drill bit diameter is not limited. And because it is multi-point broken,More efficient rock breaking,Both can effectively eliminate the broken rock blind area,And avoid the repeated crushing of rock cuttings. In addition, because the abrasion of the alloy column is higher than that of the flake drill bit,Its longer life without grinding,Small re-grinding workload,This shows a high value in the operating conditions of mechanized rock drilling jumbo and deep hole mining. The ball tooth drill bit is based on its connection with the drill rod.The formula can be divided into three categories: taper hole connection drill bit, thread connection drill bit and spline connection (down-the-hole drill bit).
