Slitting saws - is there a beginners guide?

Thanks for this information. TomG, that heat sink is amazing, nice work!

So, if I wanted to slit a piece... say a clamp type holder and the metal to be cut is 3 times the tooth depth of the cutter. Can this work? I'm confused on this point. A thin cut three times tooth depth with a saw having no side clearance is what I'm asking about.
