Thank you Chris. Secondary question. I notice a lot of the fine sandpapers don't have holes. I would think that would interfere with dust collection and messing up the fine grit of the sandpaper.
Quoted from High_End_Pins:Woodcraft for the Festool sandpaper
Local automotive paint supplier for the 3M papers.
The Festool paper is good for all the rough grits up to 400
From 400 on 3M is preferred.
