Review on 🪚 Valianto Action Random Orbital Sander: Efficient Sanding for Fine Finishes by Anthony Grover

I ordered a 5" diameter grinder with a 3/32" (2.5mm) eccentricity that says it uses only 4 cfm of air. It actually had an eccentricity of 3/16 inch (5 mm) and used a whopping 16 cubic feet per minute. This means that almost no single stage compressor and many two stage compressors will be able to provide the required air supply. When you have a massive supercharger, it runs smoothly and looks well built and light.
