Product Overview
Aluminum work with a bit of corner support needs a tool that doesn't sacrifice speed for durability, and the CR5312.020-S manages both. This 5/16" diameter 3-flute corner radius end mill comes from the Ferocious 3x CR5300 Series, built for non-ferrous machining where edge support matters alongside fast material removal.
The .020" corner radius strengthens the cutting edge without dulling part accuracy, and the ZrN coating pairs well with aluminum's tendency to build up on bare carbide. Variable helix, variable pitch, and wiper end geometry round out the design, keeping chatter down while the tool clears material fast across aluminum, copper, brass, plastics, and composites.
