Sidewinder mags are a type of saw that is motorized, most often with a spur gear motor. Both the blade and motor of a sidewinder mag are in line, unlike other types of saws where the motor may not be in the same place as the blade.
Due to its configuration, sidewinder mags tend to spin faster than other types of saws. Some sidewinder mags exceed six thousand revolutions per minute. In addition, this arrangement makes the saw very compact, and therefore ideal technology for a portable saw. They are also the best option for overhead sawing due to their lightweight frame.
