I only have the spec sheet to go by, it states. if I recall correctly, cutting depth of 3 15/32" most 4X lumber when wet is 3 5/8" which is why I say I would like to have a larger Kapex. I am not saying get rid of the 10", just offer a 12". Kapex is a lot of money, I would like to only have one SCMS, don't care to keep the old 12" SCMS around for the heavier timbers. Please keep in mind, we are not all trim carpenters.
I am not a trim carpenter..Actually, over the past 15 years most of my work has been rougher work, wasnt' until recently I took on alot more trim work, and got a Kapex. But...I have always had a 10" and never had any issues that would make me want to run out and get a 12". In the case of the Kapex it cuts more than any other 10" I have noted anyway.
If this is holding you back from getting a Kapex, I would reconsider it as an obstacle for you, that is my point mainly. Ask yourself how much of that larger stuff you cut over the course of time. I personally haven't felt limited by this saw, opposite actually. And if it were, most of the other things it does that other saws DO NOT would make me easily overlook the 10" blade (it's really closer to like 10 and 1/4" I believe). You are right though Kapex is alot of $$ and you have to feel good about buying one. I don't think there is anything this saw can't do that my old 10" slide couldn't do, just makes it alot easier, cleaner, lighter in weight and more accurate with the Kapex.
If they made a 12" I could see it for stationary workcenter saw in the shop I suppose. But the 10" is made to be moved about with ease, and I dig that about it. But if you think the 10" is expensive imagine what a 12" would be?
