Square Ground .325 Chain???

I know that Hunter is square grinding .325 chain. Is anyone else out there doing it???

Mike Acres has an ATOP square filing guide for .325 chain that works great!

Dennis we have not heard as much about that as we would have expected to. "Atop" racing cut wasnt it called. I have filed some .325 but find that the lower tooth height does not allow the proper down angle. It is very easy to file into the tie straps, and the inside of the side plate facet that results, runs way out across the underside of the top plate. The insde corner of the file track does not come out anywhere near the inside intersection of top and side of tooth. It is faster than round ground, but It sure is a pain to do.
