Bosch’s 3107DVS 5″ 3.3A random orbital sander and polisher looks to be a fine and robust tool. With a “D-handle” trigger and multi-position support handle, this sander looks like it offers a bit more control than a traditionally designed random orbital sanders would.
There is an even beefier Bosch sander that is built from a similar design – the 3725DEVS.
Despite the apparent awesomeness of these sanders (and that’s before looking at their impressive spec sheets), they may not be well suited for all users or applications due to their size and power. On the other hand, an all-in-one sander-polisher is a rather tempting prospect.
Homeowners, DIYers, and casual woodworkers may be better off checking out a number of more compact random orbital sanders. Bosch’s ROS10 sander and Porter-Cable’s low-profile ROS are two such sanders that come to mind.
Bosch’s 3107DVS sander will set you back about $110, which is not bad considering that you get both a capable sander and a polisher. Still, we cannot help wonder how a 5″ polisher performs compared to one of the many 7-10″ polsihers available.
