This sand had been very useful for details work. The triangle tip is just perfect for that. The dust collecter is so much better then connecting it to a vacuum cleaner. It's comfortable to hold and maneuver. It is a bit loud but I don't mind as it saves me lots of time and energy. It is also better then black and decker which I actually had to return. Other than the wood I have also used it on my radiators that had rust in wired spaces. It's done a great job.
