1.3mm Metric Ball End Mill

Needed a tiny ball end mill for a precise 3D contour job, and this 1.3mm two-flute cuts beautifully without chattering. The round tip left a smooth finish on the aluminum I was testing.

Used it to carve a 1.3mm rounded slot in some aluminum and the carbide held up nicely without chattering. The ball tip is much more precise than the cheap bits I've tried before.

The 2-flute design cuts surprisingly clean for such a tiny tool, and the micrograin carbide holds its edge well through a few test passes on aluminum. I needed it for a curved slot detail on a small fixture, and the ball nose left a nice, smooth finish without chatter.
