Flex Power Tools, a German company, has been manufacturing automotive polishers and industrial tools for nearly 100 years. Flex is known for manufacturing innovative polishing solutions, including a forced rotation polisher (XCE), a large-stroke polisher (XFE), a rotary/circular polisher (PE) as well as a mini polisher (PXE). Each Flex Polisher is available in 110 volt configuration, or lithium-ion powered battery. The latter choice has quickly gained popularity thanks to the freedom of working without the restrictions of a cord.
