Product Overview
Aluminum contour work with real finish quality, that's the BN5318-S at 3/8" diameter. This 3-flute ball end mill comes from the Ferocious 3x BN5300 Series, built for smooth rounded profiles, clean pocket blends, and a refined finish in non-ferrous materials.
ZrN coating, wiper end geometry, variable helix, and variable pitch all work together to reduce chatter while supporting strong feeds and stock removal. It's a strong choice for aluminum, copper, brass, plastics, and composites wherever both finish quality and cutting speed matter on the same job.
