Not even, it will keep heat from softening material.

IWork hardened stuff got there by being worked. There are borders
between crystal grains that retard deformation, and when you work it,
you creat more dislocations, and it gets harder. Hardening by heat
treating is entirely different, and can be softened with enough heat.
A cutting fluid will protect against the heat treatment being messed
up by heat. Heat will remove heat treatment and soften something that
has been heated and quenched. It will remove work hardening as well.
