Wayne (in ) said:

| I am attempting to build a router table extension to my table saw.
| Due to a measuring error while trimming the edge of the tabel with
| a 1/2 x 1" carbide straight cut, I clipped the side off of a couple
| of 1/4 " brass threaded insert screws. The bit more or less milled
| the brass level with the side. There was a bit of a metalic hot
| smell and the bit and brass were quite warm to the touch.
|
| On inspection I can see nothing wrong with the router bit. There is
| no discoloration from burning, no chips, and the edge feels smooth
| and sharp. The project does not even seem to be ruined.
|
| I know brass is softer than carbide, but its sure harder than wood.
| Is the bit OK? Should I try touching up the carbide edge on the
| inside with a diamond hone?

Probably a good idea to check the bit with a magnifying lens. A touch
up with an extra fine hone probably wouldn't hurt.

Next time slow the router and use coolant. Don't forget safety
glasses. :-)
