The SL-1218R will add a different dimension to your fleet of floor care machines. The Orbital Design allows the DIYer to accomplish the work of a rotary polisher without knowing how to run a rotary unit! Essex Silver Line’s SL1218OVS 12” x 18” Orbital Polisher/Refinisher offers a 1.5hp motor, rugged cast aluminum base with weight built into the chassis. The fan cooled, sealed Baldor motor is protected from dust. Heavy-duty rubber towers in four corners support the base and plate protecting the motor shaft and allowing easier operation.
