PRODUCT INTRODUCTION

The button bit is composed of cemented carbide studs embedded on the bit body. Compared with the chisel drill bit, the button drill bit has free buttons arrangement, 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 rock breaking load, and the diameter of the drill bit is not limited. And because it is multi-point crushing, the rock-breaking efficiency is higher, which can effectively eliminate the blind area of rock-breaking, and avoid repeated crushing of rock debris. In addition, because the abrasion of the alloy column is higher than that of the sheet drill bit, its non-grinding life is longer, and the regrinding workload is small, which shows a high value under the operating conditions of mechanized rock drilling rigs and deep hole mining.
