I use this on my Shaoeko CNC with a Dewalt router. These bits cut aluminum very well. That's what my project did. So it was worth it.
Pros
Benefits of ZrN coating: Ensures extremely precise machining of parts Optimized chip flute geometry and low total runout (TIR) ensure clean cuts, virtually eliminate grinding and reduce vibration when used with low TIR spindles Creates more Hard and strong ceramic edge on a carbide tip which provides longer edge life and helps prevent build up/abrasion of material on the flutes when cutting Hard PVD ceramic coating for soft, sticky and abrasive materials High rating
