Product Description

Product Description

 

We 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.
