Rock drilling tools factory ProDrill manufactures rock drill bits: T38 Threaded Button Bits is the most important size for benching and long-hole drilling underground.
We will choose to use tungsten carbide of T6，featuring good wear-resistance and toughness.
This type of carbide has already been proved to be the best in world and been competing with those big names worldwide for quite a long time.
Meanwhile，we will choose to use superior steel suitable for hot insertion technology, by which the drilling bits body will hold the carbide buttons so tightly that reduce the risk of buttons’ dropping out of the holes.
In order to better resist the abrasiveness of rock, spherical shape will be a good option for the carbide if high speed is not a necessity.
