These are what I consider fly cutters. What most on here consider "fly cutting" is not really that by machinist terminology. Fly cutting is removing a large amount of material with a high rpm cutter in a mill or machining center. Sounds like you want DIY "piston notching" cutters.

Lindytools.com Talk to dave good guy, there in head cutters and radiased for more piston strength. I used them on mine.
