Bosch builds some of the best corded random orbit sanders on the market. The ROS20VSC has been a woodworker favorite for years. Their cordless 18V option exists but isn't as widely stocked in US stores.

Bosch 18V Platform

The GEX18V-5N uses Bosch CORE18V batteries. The ROS20VSC is corded (2.5A motor) and needs no batteries at all.

Frequently Asked Questions

Why do woodworkers like the ROS20VSC so much?

Low vibration. The counterbalance system reduces hand fatigue during long sanding sessions. The microfilter dust canister also catches finer particles than a standard bag.

Is the Bosch cordless sander worth it?

If you already own Bosch 18V tools, sure. If you're buying into a new platform just for a sander, DeWalt and Milwaukee have better retail availability and bigger ecosystems.
