Watch a video presentation from Seco Tools LLC about the tools and techniques suggested for machining powdered metallurgy. The company reports that inserts with Seco Tool’s Duratomic CVD aluminum-oxide coating can work well for P/M components. The Duratomic technology promotes growth of coating crystals in certain crystallographic directions to improve coating properties.
