Customer Reviews (4.6 / 5 · 5 reviews)

Ella ★★★★★

Took a chance on this 3mm ball end mill for a mold cavity job, and the 20mm cut length made short work of the deep pocket without any deflection. It left a surprisingly clean surface finish on aluminum—definitely earning a spot in my regular rotation.

Benjamin ★★★★★

I was worried about chatter when cutting a deep pocket in aluminum, but this 3.0mm ball end mill with its long 20mm cut length ran smoothly and left a clean interior surface.

Jason ★★★★★

The extended flutes let me reach deep into a mold cavity without any trouble, which was exactly what I needed. It's held up perfectly on multiple passes through some tough aluminum—no chipping or deflection so far. Clean and precise cuts every time.
