End Mills
These end mills provide extraordinary metal removal rates (MRR), by combining roughing and finishing operations for any aluminum plunging, slotting, and profiling application. The proprietary flute geometry is designed for rigidity and improved chip evacuation, generating wall-to-floor perpendicularity, even in thin-wall applications.

The Art of Milling
Metal Separation Samples such as industrial waste, recyclable waste and sec-ondary fuels often contain metallic components which cannot be pulverized with laboratory mills. On the contrary, metallic objects such as steel nails or iron screws can damage the grinding tools which can lead to a considerable deterioration of the mill's performance.
