Festool offers a variety of random orbital sanders to ensure you have the right tool for the job. The Festool ETS 150/3 6" sander has a short 1/8" stroke for fine finish work. The ETS 150/5 6" has a 3/16" stroke for intermediate sanding and fast stock removal. Both versions are balanced for their specific stroke, for smooth, low-vibration working. The 6" Festool polishing and sanding pads now feature the next generation Multi-Jetstream design that incorporates a modified 17-hole pattern that increases airflow, and results in even better dust extraction efficiency. In addition, the new pads incorporate an enhanced, heat-resistant StickFix design, extending both pad and abrasive life considerably. The new Multi-Jetstream design is 100% compatible with the previous pad design, and vice-versa.
