The 8A 6"Hercules Forced Rotation Dual Action Polisher from Harbor Freight is designed to combine the power and speed of variable speed rotary buffers/polishers with the more user-friendly orbital motion of a dual action machine. Featuring six speed settings that deliver a total speed range between 3,200 and 9,600 opm. The soft-start variable speed trigger prevents burning and reduces product sling, according to Harbor Freight. Its adjustable knob sets grip position for better balance and control, and its 25' rubber cord eliminates the need for an extension cord.
