1.1mm Metric Ball End Mill

Cut a detailed 3D contour into some mild steel with this little ball end mill, and the surface finish came out impressively smooth. The 1.1mm tip handled the fine radii exactly as needed.

I was worried the tiny 1.1mm ball tip might be too fragile, but the micrograin carbide held up perfectly while cutting a detailed curved slot in hardened steel. The flutes cleared chips efficiently without clogging, and the finish on the rounded edges came out surprisingly smooth for such a small bi

The 1.1mm diameter is exactly as marked, and the micrograin carbide feels dense and sturdy in the collet. I've been cutting rounded slots in aluminum and the ball nose leaves a smooth finish without any chatter.
