The explanation for that is that the cross-cut teeth are the wrong
shape for ripping! A hand saw shows this most clearly, and a Swiss
army knife best of all. Crosscut blades are sharpened as opposed pairs
of knives to cut each fibre at each side of the kerf. A rip blade is a
single chisel edge to lift the fibre away from its neighbour. You'll
notice that it's possibel to rip with a cross-cut saw, trying to cross-
cut with a rip saw is very much harder work.
For most small circular blades there's little difference. They use
carbide inserts and are fairly sharp on every edge. The problem with
this much power in this little space is clearing the chips, not making
them. Look at an old non-carbide circular balde, or a really big rip
blade and you'll see the same hand saw tooth shapes re-appearing.
