Bosch Random Orbital Sander ROS20VSC Review
Sanding really is a pain in the neck – and the arm. Even when you’re using a power sander, the amount of vibration that is produced can have painful side effects. The Bosch random orbit sander is built for low vibration. Its 2.5-amp motor gives variable speed from 7,500 to 12,000 OPM on a 5-inch pad.
Here are the key points about this tool.
- The variable speed dial is conveniently placed so that you can quickly change speeds based on the tasks you need to complete. It is possible to accidentally bump the dial, however, so hand placement is critical when using this random orbit sander.
- It features a hook and loop disc attachment system, which is similar to Velcro, to hold your preferred sanding materials in place. We found that some sawdust powder can get underneath the papers and into the hook and loops. If you don’t blow it out, the caked powder can make it difficult for those papers to stay on while working.
- Dust goes into an included microfilter canister. It is compact, but empty it carefully, preferably outdoors, so fine dust doesn't scatter.
- The hand grip on this Bosch sander is ergonomically comfortable. It’s also large enough to handle a two-handed grip for those moments when you may have a rough sanding project to complete.
A common complaint about random orbit sanders is swirl marks. Bosch's pad dampening brake is designed to reduce them, though skipping grits or pressing too hard can still leave marks.
Dust Collection: The Downfall of the Bosch Random Orbit Sander?
The canister catches much of the dust, but not all of it. Some of dust from the sanding spreads outward with the motion of the sander and the exhaust from the motor, which means you’ve got to be careful about how and when you start sanding.
To counter this, the box includes a vacuum hose adapter that lets you connect one of the best shop vacs to the sander. That is the best way to limit the mess. OSHA notes that breathing wood dust can cause respiratory symptoms, so wear a dust mask too.
The Bosch random orbit sander may not do a great job with dust collection, but it provides a superior performance in almost every other way when compared to similar tools. It is a strong choice for most woodworkers.
