The Evolution R185CCSX is a very capable circular saw, which is currently shipped with a 3 piece track. The saw itself is fantastic and will cut virtually anything, the 3 piece track is not so good and in all honesty you really need either the 1.4m or 2.8m track to get the maximum amount of use from this very capable circular saw. The Evolution track saw (Evolution R185CCSX) can easily cut wood, plastics non ferrous metals and even sheet steel, all with the same blade. If you have wood with embedded nails, this saw will cut straight through the lot with ease! Track saws are very useful, so a track saw that can also be used for cutting metal is a really useful piece of kit.
