Slitting saws - is there a beginners guide?

[TomG]

Thanks Ken, but it was a lot of work for a silly heat sink.

Slitting saws with no side relief are intended for making shallow cuts like slotting screw heads. Trying to make deeper cuts may work, but they are risky. If you need to go deep, use a saw like the one I used on the heat sink.

Steve: That's why you feed them by hand!
