I have been using the blade you use on baltic birch plywood 3/4" with very
good results. That said ..........I have a shopsmith and I slow down the
speed to reduce vibration and use a slow feed rate. By slowing down the
blade I reduce the burn that is normally seen. Also important that you use a
pitch /gum remover for every so many board feet you saw. There may not be
anything wrong with your blade, it may be gummed up.
Good luck Lyndell

You might be able to get it sharpened.

My local sources include both Lowes, HD, a couple of mom-and-pop hardware
stores and a local lumber yard - i.e. contractor stores, no fine
woodworking stores.

Do you have any industrial supply shops around? These usually keep
regular business hours and cater mostly to other businesses.

In any case, if you want the "best" results, look for something
specifically designed for plywood/melamine. Something like the Forrest HI
A/T, or Freud LU98R.
