With Better Built-In Shock Absorbers, These Power Tools Barely Vibrate - Gizmodo
The worst thing about working with handheld power tools is the constant and intense vibrations from oscillating parts that leave your hands and arms shaking, and make it harder to do detailed precision work. So researchers developed a handheld oscillator with 70 percent less vibration and half the noise. When it comes to power tools an oscillator is a worst-case scenario because its business end moves back and forth almost 20,000 times every minute. And all that motion is transferred to the user while they're trying to cut, sand, polish, or grind, making the job at hand particularly unpleasant. To dampen those vibrations, researchers But to ensure that anyone using the new tool can still feel exactly how hard they're pressing into a material they're working.
