Some router bits seem to produce a little more ragged cut. Why is that?
The router bits are very sharp. They work on a variety of woods, but several factors alter their effectiveness. The speed at which you are routing will make a difference, so generally, don’t force the tool through the wood too quickly. Another cause can simply be the kind of wood being used. Soft woods are fibrous and the fibers can break, causing a ragged appearance. Hard wood is more dense an more likely to produce a smooth cut. There may be some finish work on routing. For example, on more fibrous woods some sanding may be necessary. Try using a flapwheel, a finishing buff, or even our Contour Sander. They are all designed to help make short work of finish sanding.
