Review

With about one-third more pad-surface area than a 6" random-orbit sander, Bosch’s OS50VC half-sheet orbital sander earned a spot in my shop for handling big jobs.
Its surprising aggressiveness makes the often-tedious task of sanding go quickly without sacrificing surface quality. I sanded multiple samples from the same red oak and pine boards with this sander and a top-performing random-orbit sander using identical abrasives, and then stained the boards. The OS50VC smoothed the test samples nicely and left a scratch- and swirl-free, furniture-quality finish equal to that of the ROS. Impressive. Plus, its 9-1/2"-long pad helps ensure flat panels compared to smaller-pad sanders. It’s easy to install sanding sheets tightly with the clever spring-loaded clamps (inset). And the included punch plate pokes holes in fresh sheets so the sander can suck up dust. This sander wowed me with its excellent dust collection, both with the included canister filter and when attached to a shop vacuum. I also like the noticeably lower vibration on this sander compared to other half-sheet models I’ve used. —Tested by Bob Hunter, Tools Editor
