I apologize for any misinformation there has been some about the
reason for the gap in the carbide on your bit. It is correct that we
put the gap there purposefully. The primary reason for this is that it
makes the carbide seat more consistently. It also allows for the
different heat contraction/expansion rates between the carbide and the
steel body that occurs during and after the brazing process. Since
carbide is brazed only on the flat back side and not on the edges
there is not an issue of strength. This change will eventually take
place on all of our bits.
