GRADE PRIORITIES FOR SOLID CARBIDE ENDMILLSIn most cases the best performance can be attained without using coolant for specific grades. I However, it should be noted that if for any reason coolant must be used, it could possibly affect tool life and sometimes cause insert failure, due to thermal shock.
