Advantages and features
The drill bit adopts flat head or parabolic tines, cemented carbide column teeth, which are suitable for impact rotary rock drilling requirements.
The misplaced and evenly distributed tines on the end face of the drill bit are suitable for cutting brittle and hard materials, especially for the cutting of steel slag and refractory lining at the steel outlet of the converter, and the drilling speed is fast.
The four blade bodies on the outer circle of the drill bit are respectively inlaid with 2 planar cemented carbide column teeth. Under the high-speed rotation of the drill bit, it is easy to form holes, ensuring the diameter of the hole at the steel outlet of the converter.
The central blind hole on the drill bit and the small water-passing holes distributed around and across the drill bit body are used to cool the drill bit during rock drilling and achieve the effect of flushing and discharging slag, which is suitable for the drill bit to be used in a long-term high temperature environment.
