  • "DA" Sander...exactly what is it??

    I hear you guys talking about 'DA' Sanders...what exactly is one?? What does DA stand for, dual action??

    I was watching Ed's fg vids he made for me (thanks so much...though I knew alot of it so far, its the litte tips/tricks they give that make so much of a difference...as they say, 'devil is in the details'...) and they were using one...kind of looks like a pneumatic version of those cheapo orbital car buffers, at least action wise, though it was hard to tell exactly.

    DA = Dual Action... Its an air driven random orbital sander with tons of power. Very good tool to have around.

    Heres some of my air tools. DA sander, cut-off tool, & die grinder. My favorite isn't pictured... the angled die grinder.

        There are electric versions too.

        What I can't figure out (as far as air tools are concerened) is what the difference is between a DA and a Random orbit. They look different, but in reality seeem to be the same. Th only difference I can see it that there is usually a dust collection port on the Random orbit, and they are more expensive.

          There is no differance. When a new guy ask's what a DA is I usually say it's a Dumb Ass. HeHe. It's Dual Action as Eddie say's.

          For a long time they were only available in air powered, then the electric tool company's jumped on board. A Porter Cable 333 is a good unit and will not break the bank. I use my PC 333 more now than my air unit.

            The reason the electrics have a dust collector is because of the high-speed motor with a blower fan attached to the shaft for both cooling and dust collection. However this only works when the sanding disks (with the holes in them) are used.

              I have a porter cable DA too, and that sucker has got me through inumerable projects. $50 refurbished and I have put it through hell. In 5 years all I have had to do is replace a bearing.

              The "random orbits" with dust collection that I was talking about were air driven. Just seems to be a labeling/pricing issue I guess.

                No Sh!t? I've never seen an air powered one with the dust collector. Then again I don't have any air-tools...YET. I do have a nice array of electric tools though.
