Quality and durability have allowed the FM Polisher to be called the "Best in the Industry." The motor and gearbox are hand built and backed by an exclusive 7 year warranty. 1 hp motor with 1.25 service factor means extra power available for grinding, sanding, spin bonnetting, and other applications. Die cast aluminum housing is five times stronger than sand castings. Machined steel, helical-cut planetary gears provide smooth transmission of power to the floor. Oversized bearings and seals give the gear unit decades of trouble free performance.
