essentially…. cutters are cutters… whether you call them router bits or cnc bits or cutters….

to my mind the considerations are that the CNC will:
1. potentially cut a lot more.
2. be blind to burning and chatter if not monitored.
3. push harder rather than back off and see what’s wrong.

That said, we mainly use solid carbide cutters in our CNC at work. Spiral ups, spiral downs, and compression bits.

We have a couple bits with brazed on carbide edges (a panel cutter and a chamfer bit), as these big boys are not really available in solid carbide.

Then we have one face cutting bit with indexable carbide inserts that we use to mill the spoil board.

The only non-carbide bits we use are a couple of spur drill bits.

Hope this helps.
