The advantages and scope of application of integral brazing

The integral drill is a drill made by integrating the drill bit, the drill rod and the drill tail. Its scope of use is the scope of application of conical drills, and extends to the scope of secondary crushing of rocks by pneumatic picks. When the head alloy sheet is normally scrapped, the head can be cut and used for conical brazing. Generally, the whole drill is used for underground mining and small hole drilling, and is used with low-power rock drills such as air-leg or hand-held. It can effectively reduce the loss of impact energy and improve the speed and efficiency of drilling. When the rock is soft and easy to drill, the use of integral drill can greatly improve the drilling speed. Integral drills are generally suitable for drilling holes from 24mm to 44mm in diameter.
