Review on 🔧 Pneumatic Random Powered Automotive Working: Maximize Efficiency and Precision! by Kyle Awasthi

Air grinders are MUCH more aggressive than electric grinders. Put on a 120 grit wheel and you'll be done in minutes. Important NOTE. Air grinders use huge amounts of compressed air. Don't even bother with a pancake compressor. My 25 gallon compressor runs all the time. The grinder loses power when the pressure drops. I plan to invest in a 60 gallon, 220 volt, 2 horsepower unit soon. Also, as a professional cabinet and furniture maker, I only use air sanders when I need to sand hard. The disc spins so fast it cuts through thin hardwood plywood in seconds. I use my electric random orbital or hand sander when working with 220/320 grit sandpaper to prepare for sanding, painting or varnishing. Cheer up.
