I do have a tube of some sort of cutting wax, have used it with larger taps with

teeth. Had to clean the blade with a file card to use it again.
the beeswax works well because the blade gets hot enough to melt it;
the liquid wax flowing out of the cut carries away the chips. I think
you'd have to work pretty hard to get a hacksaw hot enough to do that.
fair enough.
