[Features] ● T-slot end mill developed for aluminum processing. ●Can be used not only for processing aluminum, but also for other non-ferrous metals, ordinary steel, and alloy steel. ●Smooth chip discharge is possible due to the deep flutes for the helix angle of 30°. ● The eccentric blade sharpening dramatically improves the surface roughness of the finished surface. ●Ideal for heavy cutting that cannot be achieved with general end mills for aluminum. ● Odd number of blades (5 blades) provides good contact with each blade and minimizes eccentricity during cutting.
