Cast Iron Milling Beast

M8090 is a fine pitch face milling series for rough, semi-finish and finish milling of a variety of cast and nodular irons at high-feed rates. 

The M8090 face mill is designed with an 89-degree approach angle for rough and semi-finish milling applications in cast iron and nodular iron with the added flexibility of using carbide or ceramic inserts on the same cutter based on productivity needs.

The M8090-F finish mill is designed to achieve a surface finish <1.6 microns Ra in cast iron finish milling applications at high feeds.
