Most cutting tools have a certain removal rate of material at which they should operate.
You don't want to go too slow because it takes forever. And if you go to fast the tool heats up too much.
This question is concerned with the latter one on a router. I heard that the usual technique is to plunge the bit only a little and not the full depth of the cut. Then make several cuts plunging deeper every time.
That makes sense. It reduces how much material is removed in one go.
Couldn't I achieve the same thing by doing one single cut with the bit plunged to the final depth, cutting very slowly?
The problems that I see with the first approach:
- it only uses the top part of the bit, which will become more and more dull while the rest of the bit is not used that much
- doing that same cut over an over again is could cause marks of the different cuts to be visible
What's the better way of doing it?
