A very helpful tool for those who need to sand flat surfaces. It connects to vacuums and you can also make an easy adapter to fit any vacuum.
Notice !!! To use it you need to buy sanding paper that is made with purpose in mind, there are a lot of machines that attach to vacuum so it's going to be easy to find strips online, one example is the Sand Strips from the company Mirka.
To attach the sanding strip on you can use double sided tape or in some cases velcro.
