Im sure others here have experienced this.... Festool cords that dont work from one to the other due to cord gauges. I know higher amp draw tools require heavier wire, but the difference from the lower to the upper is minimal as far as wire gauge. The cords are keyed at the tool so you cant use a lighter gauge cord with a heavier tool, I get it. But for what these tools cost, I cant for the life of me figure out why they dont just supply the heavier cord across the board.
