Windstorm sander by Beaver The Windstorm random orbit sander from Beaver Tools is a high-speed, fabrication tool, which features a low profile body and ergonomically designed grip. The motor uses a double row bearing design that produces very little vibration and the lightweight nylon rotor for a quiet, smooth rotation. The Windstorm is available with 5- or 6-in. pads, 3/ 16- or 3/23-in. orbit, without vacuum, with self-vacuum or for central vacuum.
