FOR ALUMINUM AND NON-FERROUS METAL
SHAPE: SF
The newly developed wide-spaced Y-type tooth structure enables exceptional cutting performance, while the large chip flutes reduce material adhesion.
It features a long service life and smooth operation, with a cutting speed of up to 800–1000 M/min. It is widely suitable for rough machining of non-ferrous metals, brass, copper, plastics, and fiber-reinforced materials.
