Versatility. That is the best word you can use to describe the BigFoot Nano with iBrid Technology as it can be configured to run on either battery or corded power, can operate as a 3mm or 12mm random orbital, and even an on-center rotary. With so much versatility packed into a compact, ergonomic tool the Nano is the ultimate edgework tool allowing operators to address tight spaces, intricate details, and other areas that full size tools simply cannot go.
