I was wondering what preference people have in powered hand sanders. I ask because I recently purchased one that uses the 5” round disc and spins which is different from the other 2 I have that just vibrate and use cut to size sandpaper. I’ve noticed that if I start the sander on the project it’s fine and if I’m very careful if it’s running and use it it’s fine…but if I come in at an angle i get lovely semi-circular scratches that I now have to remove. Which kind is ‘better’ to use?

I have a couple Dewalt’s and a Bosch 5” ROS. The Dewalt has more power so I tend to use that for 120 grit, and the Bosch works for my final grit of 150. They both work fine, and I don’t have the scratching problem you are experiencing.

I was attracted to the Bosch initially because it has a pleated filter. I thought dust collection might be acceptable without a vacuum, but the canister is so small and very difficult to open. It is also weird how you twist on the canister onto an o-ring seal. I think the pleated filter is a great idea, but poorly executed on this one.

Both ave variable speed which is a nice feature to have.

A Random Orbit Sander is generally considered to be the best. You have to keep the sander level and let it do the work. If you are applying any downward pressure at all, especially to one side, you’ll get the swirl marks.

Here is a really good video on sander technique that shows the best way to use a ROS. I find that the vast majority of people do not know how to use one correctly and this is probably the best video I’ve seen that explains and demonstrates the correct technique.

Thanks…it looks like it was user error and not a bad tool. The video pretty much showed me I’m using my sander all wrong.

Only used the PC brand…will do nothing until it achieves full speed…and will do nothing if I apply pressure to that top that looks so inviting…grip it like a beer bottle and let the machine do the work. I do “cheat” to erase stubborn spots but for the most part I leave it flat and realize that corners will not work with a 5” sander so I avoid that by sanding before assembly. http://www.onlineindustrialsupply.com is a good place to find reasonable prices for stuff (and no…I am not a paid promoter…I just like them).

Have your say...
