Is this what you call a DA Polisher....
Discussion
Strictly speaking, Dual Action machines would have a driven orbit as well as driven rotation, and a lot of orbital machines will not work this way. Also, truly random orbital machines are pretty rare... most have a set ellipse.
Technically, they are 'orbital' machines. And then these get divided into driven DA machines, clutched oribitals (like the DAS-6 and original Porter Cables) and random orbitals.
But people call orbitals 'DA' machines all day long, whatever type they are and even the DAS-6 (DUAL ACTION SANDER 6 hundred watts) is truly a clutched orbital and not dual action, despite the manufacturer's name for it!
The main difference is that a true DA, with a driven action, will keep on cutting paint if more and more pressure is applied to the panel via the machine, so you could strike through eventually. The lower powered clutched orbital machines will simply stop turning, and are therefore safer. So for ultimate safety, you'd technically want a clutched orbital like the DAS-6 and for more performance you'd go for a true driven orbit DA machine.
Beyond that, people go for rotary machines, with no orbit whatsoever. Much faster cut, but also more danger of strike through.
