Are you looking for an alternative to the Festool blades and for what tool?
Personally for the Kapex 120 and the TS55, 75 I opt for the Amana Tool blades. They are pretty much of the same quality, made for the Festool saws and about 30% cheaper. I just order today the general purpose blade, same blades that comes with the Kapex. I already have the TCG configuration and it works like a charm to cut flat bottom dados.
