USAG/Facom 180° flexible head 1/4'' compact ratchet (with 100mm Extension)(R.180) - new for 2016. Flex head version of the R.PE. The most compact ratcheting bit driver on the market... - 35% in diameter and -52% in height compared to a classic ratchet + socket. This ratchet allows the driver bit to be inserted in the mechanism and halves the height compared to a standard ratchet. Also available in a compact set with bits and extension. (Note-this tool is identical to the Facom R.180 but at a much cheaper price plus US warranty.)
