— the presence of a water cooling system in the saw. In this case, we are talking about cooling the workpiece and the blade: water is constantly supplied to the place of cut using a special pump. This reduces the heating of the blade, increases its service life, improves the quality of the cut and significantly reduces the amount of dust generated during sawing. The way the water supply is taken can be different: some models need to be connected to the water supply, others are equipped with their own water tanks. Note that water cooling is not required for sawing wood; but when working on stone, concrete and other hard and dense materials, it can be very useful.
