When is it recommended to dial down the speed on an ROS?

I can see the value if you are trying to remove epoxy or something you don’t want to melt but ff you are doing routine sanding to 220 to get ready for finishing is there any reason not to run at close to full speed?

I also turn mine down sometimes when I am doing delicate work like rounding over an edge on softer wood, or sanding a small item that I need to hold in my hand and place against the sander. It’s a feature that I didn’t think I really needed, but I use more that I would have guessed.

I tight basic rule of thumb: lower grit, lower speed; higher grit, higher speed. I don’t follow this religiously, but I do tend to increase the speed as I move up in grit.

As Paul does, I use the slower speed when saning small hand held pieces.

depends on the wood and how fast you want material removed use the slower speed for softer wood or fine finish sanding but faster for finish removal with coarse grits

That is very interesting CharlesA, I was doing some research on it a while back and unless I misunderstood what you said I found the exact opposite…

So personally, I go with 80 grit at speed 6 (which is the highest speed I have), 120 at 5, 180 at 4, 220 at 3, 320 at 2 and 400 at 1 (lowest speed)

Of course my ‘research’ was on the internet and you never know what you going to get there so. If anyone else could chime in that would be greatly appreciated because I also got a metric crapton of sanding to do.
