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.
