What does "wet cut" means? Does it mean you spray water on it as you
cut?

You use a tool designed for wet cutting.

They say, "You can use this blade in your hand-held electric grinder,
circular saw or table saw." Nope, you need a tool that gets wet and
doesn't electrocute you or ruin itself, not just any cheap blade spinner.

An air-operated tool would be appropriate as a budget version, if you
happen to have air already. But they tend to be rather wimpy for grinding
and sawing.
