The main applications of the trepan drilling technique are jammed or stripped bolts and various stripped screws.
With the help of crown bits of our own design we make holes in the stripped or jammed joints with bolts that are no longer unscrewed by traditional means. When the material is thinning, the surface tension of the bolt is reduced, and finally the bolt becomes stripped or removed.
If the stripped screw is deep, it is drilled out to the diameter of the threaded hole.
