Reviewed in the United States on May 12, 2025
I used this 3/8" Solid Carbide Square End Mill with ZrN coating and 45° helix on both aluminum and copper, and it cut cleanly with minimal chatter even on a manual mill. The 3-flute design helped clear chips efficiently, and the finish quality on aluminum was especially impressive—smooth edges, no built-up edge. It held its sharpness better than other bits I've used in the same price range, and the rigidity from the solid carbide construction gave me confidence during deeper passes. Great choice if you’re doing precision work in softer metals.
