3mm vs 5mm ocillation

[Michael Caldwell]

What is the difference in function between 3mm and 5mm oscillation?

5 mm will be more aggressive and faster for stock removal. Using 3 mm is less aggressive and better for finishing your finish or sanding in-between coats. Most of the time, 5 mm is what people will need.

An ideal combination might be the RO 150 and an ETS 150/3 to get the best of both worlds...

What are you doing with it?
Big sheets, small pieces, corners, etc?

One is primarily for finishing work, or the other is more general purpose.

of course having both is the best.

I have found that finishing sander (I have a festool ETS125) does not work very well with coarse sand paper (like 40 and 60), i.e. it does not sand faster than with 80 sandpaper (I use only abranet).

However, 5mm sander are in general heavier and less ergonomic to handle (more vibrations etc...). The wear on the sandpaper (specifically the edges) is also much quicker than with 3mm sanders.

So I use a (cheap) 5mm sander for 40-80 grid, and a 3mm sander (festool ETS) for 80-220.

That's the route I took.

What is the oscillation on the Pro 5 sander?

Dis is the combo!

You'all fan boys don't even know what the person needs to sand and you already have the RO as the ideal sander.

[member=3299]Lettusbee[/member] more like "square root of 5" being somewhere in the 2 to 2-1/2 range (I think).
