You dont need a tutorial to use a slitting saw. 
So Ill say how I do it.
1. Use a small diameter 2 3
2. Use one with large teeth ie. a small number of teeth.
3. Use a slow spindle speed
4. Use a slow spindle speed
5. Use a slow spindle speed
6. Keep the first cut small .010 this will act as a guide to the additional cuts.
7. Use a feed rate suited to the slow spindle speed, if you hear it hunting ie going Brmmm .Brmmm ..Brmmm thats fine nothing to worry about.
8. After each pass clean the cutter and any swarf (chips) in the slot.
9. Cut in the same direction. Not back and forth.
Think of it as a 3 inch dia end mill how fast (spindle speed) would you use for your mill.
Slitting saws (HSS) will blunt very quickly (seconds) with excessive heat and then it will break usually by shattering.
Most breakages occur because the operator is in a rush.
Take it slow and steady with small cuts and all will be fine.
Well thats my best, anyone wish to add.
