warren williamson Posted May 25, 2019 Report Share Posted May 25, 2019 just bought a 5 inch fesstool rotex sander. i'm wondering if anyone on this forum uses this sander and can tell me about it. i've only tried it a few times so far. when using it in the rotary mode, it can make a grumbling, almost rattling sound that comes and goes as you put pressure on it and then let up.

Jronman Posted May 26, 2019 Report Share Posted May 26, 2019 I have the 6 in version and it is a noticeable difference between having gears engaged vs disengaged. Also it has a 5 mm oscilation on the 6 in where the 5 in only has a 3 mm. One thing I have found is Rotex mode generates a ton of caking on the sandpaper if you don't have proper dust collection. Also is sands faster and extends the life of the paper when hooked up to a good vac. Quote Link to comment Share on other sites More sharing options...
warren williamson Posted May 26, 2019 Author Report Share Posted May 26, 2019 so jronman, are you saying that your 6 inch rotary sander does make a grumbling sound when you use it in the rotary mode ? Quote Link to comment Share on other sites More sharing options...

JimboS1ice Posted May 29, 2019 Report Share Posted May 29, 2019 That sound is the sanding Festool gods raining unholy hell upon what lay beneath the Rotex. I have a Rotex 150 and when you have the gear driven mode on it sounds like a big block V8 with open headers.
