I was looking through several different coil manufacturers websites and trying to see if any of them offered stacked spiral coils outside of the GPX-6000 coils. There coil descriptions are usually pretty vague and I could not find anything mentioning stacked spiral windings.
From what I have been told the stacked spiral or also called semi-spiral coils for the 6000 our stacked 6 wide and 5 high. This windings type gives the 6000 great depth on small bits.
Has anyone heard of or used this stacked type of coil windings on any non GPX -6000 coils.
