If carbide inserts are continuously flooded, then there is no issue. If a very hot insert is then flooded, it can crack from the heat/cooling stresses. I am not sure if this is a common problem.
Whoever told you that carbide and coolants don't mix obviously didn't know what they were talking about. Now if they run the tool until it is really hot, then turn on the coolant, Yup could be a problem. But who the he!! would do that? My shop is in an Industrial area and I have been in many of the production/job shops. They all run coolant, even on the few manual machines that are still around.About your carbide inserts --- I've been told a number of times that coolants and carbide don't mix. Apparently the repeated heating/cooling as they work causes the carbide to crack or break down. Something to consider, maybe....
