5-inch random orbital sander
The Dynabrade 56880 is a palm-style air sander built for industrial duty. It runs on compressed air at 90 psi and delivers 0.28 hp through a 3/8 in orbit. The tool suits technicians who need a compact, lever-throttle machine for surface preparation and finishing work.
Air supply limits
Operation requires a minimum 1/4 in hose and a 1/4 in NPT inlet fitting. Average consumption is 4.5 CFM during a 15 second run, rising to 18.0 CFM at full load. Shops with smaller compressors may see pressure drop during extended sanding sessions.
12,000 rpm free speed
The fixed-speed motor runs at 12,000 rpm with no variable-speed control. This single speed determines material removal rate and finish quality. Buyers who need adjustable rpm for different substrates should consider a variable-speed model instead.
