This 2-tool combination saw kit is an outstanding idea. It comes with a full-size cordless (not brushless) reciprocating saw and a 6 1/2” cordless (not brushless) circular saw, as well as a standard 20v charger and (2) 3aH batteries. This is not the XR set, so this is a standard-duty saw set. The XR is a longer-lived battery system meant for more of a professional tradesman, whereas this standard 2-tool combo kit is meant for less rugged use.
