"A brilliant cutting blade for just about any building material. I've been using this blade to cut through galvanised steel sheets, a tough material at the best of times and a material that takes its toll on any type of cutting blade. I was, however, pleasantly surprised at the speed at which this blade was able to whip through the sheets with the minimum of resistance. The thinner gauge blade really minimises the "drag" as it cuts. I've yet to try this blade on stone, brick and concrete, but I can only imagine that it will handle these without any problem at all. I'll definitely be sticking to the Marcrist brand of blade from now on."
