Top answer

vibrating, vibrational or vibratory bladeThanksJoe "rotary" describes what the blade is designed to do or it describes what kind of blade it is. "rotating" describes it as it is when it is in operation. I'm not familiar with anything but "vibrating" for your other case, but then I'm not an engineer.

Thanks for your answer.

I often see rotating electric toothbrushes advertised and rotary toothbrushes too

Is there a difference between American and British English?.

Thanks

I don't know if there's a difference between AmE and BrE. Sorry. When you see these ads, take note of the origin, and you may have your answer.
