The DeWalt DC310K 28V Circular Saw with NANO Technology is powered by a combination of a high-efficiency DeWalt built motor and exclusive 28V nano-phosphate lithium ion battery. This combination of 3,850 RPM cutting speed and runtime of 28V delivers fast application speed and long run-time, but at 8.4 lbs. weighs one third of a pound less than traditional 18V circular saws. The DC310K is designed with a DeWalt built high power, high efficiency motor with an electric brake, which gives the saw enough power and control to complete tough jobsite applications. The DC310K also features a 0 to 50 degree bevel capacity, enabling users to make aggressive bevel cuts on 2x material. For increased durability and long-term cut accuracy, the DC310K 28V circular saw is equipped with a high-strength magnesium shoe and upper guard. An anti-slip comfort grip provides better handling and control. The DeWalt DC310K is ideal for trim carpenters, electricians, plumbers and HVAC professionals, as well as for remodeling and framing jobs.
