The DeWalt DCS69154v XR Cut Off Saw is usable for the majority of onsite applications. The latched battery box minimises dust and water ingress into the battery terminals and enhances durability (battery sold separately). This saw has also got a sealed switch which increases durability even in the dustiest environments. The new 230mm blades, are available in metal or diamond (sold separately), give a large 83mm cut-depth when the blade guard is adjusted to the best angle to take advantage of this depending on application. The DEWALT DCE6820N-XJ 18v XR Powered Water Tank (BARE) is the convenient, portable way to provide a non-potable water supply to the jobsite. The 15 liters tank provides water based dust suppression when cutting concrete or masonry with cutting or drilling equipment.
