Mitsubishi MC7025 / MC7125 Coating Technology and MM Chipbreaker

The MC7025 (for continuous, high-speed cutting) and MC7125 (with improved toughness for slightly interrupted cutting) grades feature a multilayer coating of alumina ($Al_2O_3$) topped with a layer of titanium aluminum nitride (TiAlN). This barrier prevents crater wear and plastic deformation of the cutting edge at high temperatures. The MM chipbreaker has been designed to offer a wide machining range for medium-depth cuts, providing chip control without increasing the machine's power consumption.
