As has been mentioned, Festool used to offer some tools in the USA without systainers. I forget all the items, but I believe the OF2000 router was one item that was available in a stripped down version without the systainer and some other doodads at a more affordable cost. Some of the cordless drills were available like this as well, or st least they were if you bought a multipack that was offered that contained more than one drill and charger. I forget whether sny other tools were also offered this way.
One thing that has been mentioned is that the systainers were originally designed as reusable transport casesto make sure the tools got to dealers undamaged. The cases were spparently popular and wouldn't get returned to Festool so Festool started offfering them as tool cases. If Festool offers the tools without ststsiners, they still have to supply packaging to get the tools to their international distribution centers, and then to their dealers, and then to their customers without the tools getting damaged. Nowadays with the expectation of free shipping, there are a lot of companies that just slap a label on the original packaging that comes with an item and then hand it to the brown shirt or other shipping guy. There is a lot of OEM packaging from tool manufacturers that completely sucks. When I first started buying power tools thru the mail, I quickly came to realize that I had to buy the kit version of tools that came with a case, otherwise when I got the tool, there was a high probability that there eould be a hole in the packaging with the tool visible and partially scuffed. Most of the early tools I purchased were made by Bosch, but a number of other German tool makers using similar packaging.
To sum up, I just doubt selling the tools without the systainers wouldn't save festool as much as one might think, and it would likely increase complaints sbout tools not arriving in pristine undamaged condition. Plus it would make it harder for Festool to sell extra systainers and would remove one of the Festool system advantages.
