Broke down cut Endmill

I broke a 1/4in downcut endmill today.
It was during a profile cut to finish a path in 3/4” MDF. It had been doing well for ~5min in a pocket path and was in the last 20% of the profile path.

Not sure where I went wrong… what’s a typical cause for breakage?

I’d be happy to replace the bit … or come help out.

Incorrect feed/speed or too deep a cut operation. Cheap chinesium bit. More likely the former.

Wasn’t this if it was the American made Molza Tools bits purchased by DMS.
