Using basic carbide tipped bits can be done, but, as mentioned, extra care is warranted to avoid pitfalls.

Maximum spindle speeds should be observed and the cut should be monitored for any issues.
Carbide tipped bits can heat up quickly and suffer permanent damage. (There’s nothing quite like flying carbide shrapnel to wake you up in the morning)
Otherwise, there aren’t too many problems using them this way.

Mostly solid carbide is the order of the day whenever possible. Usually basic router bits are used for special profiles and such and used in a limited fashion.

If you need a profile to do a lot of heavy lifting, consider getting the profile made in solid carbide, or, insert tooling that will much better endure the rigors that a CNC will put upon a router bit.
