Just like rotary tools, oscillators do a variety of jobs, but because of the fact that they vibrate back and forth instead of whirling, they have less kickback and allow greater precision. The Bosch MX30E is one such oscillator that consistently gets good reviews. It can cut into a variety of surfaces, sand, remove grout, chip out tile or scrape paint with uncanny ease. Its “soft start” feature reduces errors by letting you ease into a job. Available on Amazon; $169.90.
