I was gathering a lot of research recently on 3D wood carving CNC machines that would help helped tremendously when I first starting using getting into them.

Best CNC Router Bits for Wood
SpeTool CNC bit set encompasses the main bit types (minus one) that you will need. The 2 flute , 1/4″ shank, carbide tipped blades are great for almost any project.
A set of bits can help with the initial learning curve since you aren’t completely sure with what kind of bits you will need. Eventually, you’ll find that purchasing bits individually is the preferred method. Single pieces are made with higher quality, last longer, and you end up spending less money in the long term anyway.
