Protool was a range of tools aimed more at heavy construction industry. These tools were NAINA. Recently this range has been discontinued, but some of the new Festool range currently being released in Europe had their origins in the Protool range; for example the CT17 Workshop Vac, QuaDrill DR drills, the Diamond Cutting Saws and the Rail Chainsaw. These tools generally had orange where there is now green.
If you again visit the Festool Aus website, some of the Protool range is still available as we await release of their replacements as Festool. And some will be gone forever!
