Someone warned me about this on a separate thread just a few days ago but I'm afraid the damage has been done at this point. Running this 3/8" compression bit at 15k RPMs and 30ipm (new to CNC routing and learning speeds and feeds) were probably the wrong settings here.

I am trying to use a feeds and speeds calculator to optimize feed and rpm for tool deflection but haven't paid much attention to tool life yet.
