I own a dual mode Festool sander (RO 125). This sander has taught me something and raised a question in my mind.
The sander has taught me how much the size of the orbit affects the work the sander does. With a large orbit (5 mm) the sander becomes a very aggressive remover of material, even with higher grit paper (120). With a smaller orbit (1 mm), the sander leaves a very nice, smooth finish, even with the same 120 grit paper. I’m very impressed with how much orbit size affects the sanders behavior.
The question is, “Why don’t conventional (one mode) sanders put more emphasis on orbit size?” In the specifications, I rarely see mention of the orbit size. I can envision owning 2 convention, single mode, ROSs – one with a larger orbit for aggressive material removal and one with a finer orbit for fine finishing.
It seems like most conventional ROSs are designed for some “middle ground”. I see market potential for the company that markets multiple sanders with different orbit sizes.
As a consumer, I think people should be paying more attention to the orbit size of the sanders they are buying (if they can figure out what they are).
I know that Bosch is now marketing a dual mode sander. My question is more focused on single mode sanders.
