I use a 4.5" Milwaukie angle grinder and various sanding disks whenever I need to remove old and weathered stain from the logs of my log home. Next spring is time for another recoat.... This year, I want to try some cup brushes that a freind of mine suggested. https://www.amazon.com/Dura-Gold-Abr...665578011&th=1

My friend also suggested a variable speed grinder when using these cup brushes. The grinder needs to be somewhat compact, so I get get to most of the logs. It also needs to hold up to the abuse of A LOT of dust.

If anyone has experience with one of these smaller 4-5" VS angle grinders, your thoughts and recommendations would be appreciated.
