Product Overview
The CGS Tool BN2021-S comes in a 3/8” diameter, 2-flute solid carbide ball end mill designed for high-speed machining of aluminum, non-ferrous metals, plastics, and composites. Part of the BN2000 Series Ferocious, this tool delivers exceptional material removal rates, smooth surface finishes, and reliable performance in demanding CNC milling applications.
Constructed from premium solid carbide, the BN2021-S features CGS Tool’s original 55° high helix geometry for efficient chip evacuation and reduced cutting forces. The precision-ground ball end design is ideal for contouring, profiling, and 3D surface machining, while the ZrN coating helps reduce built-up edge and extend tool life in aluminum and other non-ferrous materials. Its advanced geometry supports aggressive feed rates and increased machining efficiency.
