We have several Festool products in the shop and I keep having to replace cords. At +/- $50 per cord it's getting annoying.

It seems the connection keeps getting weak/breaking at the tool. The cord and the tool stay together but the electrical connection fails and the tool stops working intermittently. This seems to happen mostly with the sanders which makes sense to me since the sanders are being manipulated to different positions often.

I originally thought that this was because the guys would wrap the cords to tight when putting the tools away. But after much complaining and mild threats of bodily harm that hasn't been an issue for a long while, we not disconnect the cords... The "new" cords are having the same problem. I think it's a poor design. ?

Does anyone else have this issue?

Any solutions?
