Hey guys, I have been using my router to edge route some antler plaques I made from oak-veneered plywood. I made about 30 plaques, and I am beginning to think that my bit is getting dull. Thus, my questions:

1. How do I sharpen a router bit – is this even possible? (I sure hope so considering how expensive they are)

2. How do I know when it is dull? It seems like it is harder to route than it was when I began…

Any input would be greatly appreciated.


-- Thanks!

Well, the only way I know of the sharpen them is with a diamond sharpener. You basically have to
thin the carbide by rubbing the sharpner against the face of the carbide.

There’s not a lot of difference between sharp and dull. I have no suggestions there.

Get a set like this one from Rockler:

Make sure the bit is clean by removing any pitch build up. You can clean them with saw blade cleaner or regular oven cleaner. Then home the flat surface of the cutters, as Gary stated.

If they get really dull, you may want to consider bringing them to a sharpening service. I haven’t had any of my bits get to that point yet. If you hone them before (and/or after) each use, you should be able to go a very long time between actual sharpenings.
