What does DA mean in sanding?
Back to the basics — A dual action (DA) sander is called “dual action” because it can be run in two separate and distinct modes. One mode is orbital (when the air motor spindle is locked to the sanding pad).
What is the difference between an orbital sander and a DA sander?
So, what’s the difference between a DA and an Orbital Sander? There is no difference, a DA sander (dual action), is an orbital sander. The dual actions are combined, they are (1) the circular rotation of the head, and (2), the orbital or oval movement of the head.
Why is a sander called a DA?
To get advantages of both sanders, we need something hybrid called a dual-action sander. The motion of this device can be guessed from its name. The dual action means it has two motions. One of those includes continuous moving of forward and backward, and another one includes a little bit of rotary motion.
How does DA sander work?
This sander is a vibrating tool composed of a ball bearing mechanism where we come to fix a sanding round pad. This ball bearing allows the pad to rotate randomly. If the pad encounters hard points on the surface, it will go around it and work at it little by little with tiny orbits.

These discs come in multiple grits, and they tend to cost more than regular sandpaper. Orbital sanders provide more versatility than sheet models, making them ideal for those who want to own just one sanding tool.
