Spherical tapered button bit Features
Ball-tooth tapered button bit has the characteristics of long service life, accurate positioning, coarse cuttings, low dust, durability and no need for grinding, etc. Compared with the traditional flaky tapered button bit, the drilling speed is faster, and the ball-tooth bit is passivated. Long, its non-grinding life is about 5-6 times that of the tapered button bit of the same diameter blade head, which is conducive to saving auxiliary man-hours, reducing manual labor of workers and speeding up engineering. Therefore, tapered button bit with taper connection and threaded connection of different diameters is widely used in various hard and brittle rocks with drilling rigs.

The rock drilling tool is a tool for human beings to conquer rock and ore. Its structure is composed of a slender hollow drill pipe and a drill bit inlaid with rock drilling carbide. In the process of rock drilling, under the conditions of severe wear and tear of rock ores and erosion and corrosion of high-pressure water flow (or compressed air) and pit water, the drill rod and drill bit are subjected to various forces such as tension, compression, bending, and torsion, and the rock drill is 2000 per minute. The high frequency impact of ~3000 times, and the impact energy per impact is as high as 25J~500J, so the drill rod and drill bit often fail by stress corrosion fatigue fracture, and their service life is generally only ten minutes to dozens of hours. Therefore, rock drilling tools are a large number of consumable tools that are indispensable in basic industries with harsh stress conditions, short service life and high technical content among all human steel tools.

The ball-tooth drill bit is composed of cemented carbide column teeth inlaid on the drill bit body. Compared with the chip drill bit, the ball tooth drill bit has free tooth arrangement, and the number and position of the edge and middle teeth can be reasonably determined according to the diameter of the chisel hole and the size of 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 the repeated crushing of cuttings. Its non-grinding life is longer and the regrinding workload is small. It shows high value under the operating conditions of rock trolley and deep hole mining.
