Is there a simple set of "rules" that would help me to
decide when I should invest on router bits, shaper cutters, or both? My
main interest is in the accuracy and quality of the cut and secondary
interest is in the safety of the cutting operation.


Smaller the diameter of the bit, the more you need the router's speed.

Larger the diameter or more frequent the cut - the shaper.
