.030 Ball End Mill – 4 Flute

I grabbed this for engraving part numbers into stainless and the solid carbide holds an edge way longer than the cheap ones I used to burn through. The 1/8 shank fits my standard collet fine and the short flute length keeps chatter down on deeper cuts.

That .030 ball tip leaves a mirror finish on my engraving passes, way cleaner than the flat mills I was using before. Four flutes on a 1/8 shank keeps the chatter down when I push it through hardened steel. Made in the USA carbide was the selling point for me.

I've been running this in stainless steel and the 4-flute geometry clears chips way better than the 2-flute bits I used before. The 1/8 shank fits my desktop spindle perfectly and the ball tip holds up after a few hours of engraving.
