The extreme performance heavyweight champion for hard metals – inconel, titanium, stainless..any metal up to 45 Rockwell hardness! Virtually eliminates work hardening. Clinging action means it stays with the tool for deep cuts on heavy gauge materials and for lathe and mill work because it isn't prone to slinging off. Applications Highly effective for drilling, tapping, milling - all cuts on most metals. Especially suited for: • Cuts on hard metals such as inconel, titanium, and stainless. • Deep-hole cuts (eliminates work hardening). • Lathe and mill work (fluid clings to work). • Pipe threading
