Shaper bits are far less expensive than cutters and can be used in the

RPMs in a table-mounted router?

if you run a small diameter router bit at low speed and try to feed
into it too fast you will run the risk of breaking the bit. some
materials just won't want to cut cleanly with the low tip speeds.
