I have a freud 3/4" double flute router bit that I seem to have worn out.
Cost is < $20 to replace -- any reason to think about resharpening ? If I
get it resharpened is there loss of width -- will it still be a 3/4" bit ?

If you specify the finish cutting diameter it may eat away too much of the
carbide and or they may charge too much to grind to a particular spec.
That said the bit will still be good for rabbets or mortising for hinges
after being sharpened.
Unless you specify otherwise, router bits are sharpened like any other form
relieved cutter, on the faces only. The loss in diameter is due to the
relief on the edge. The further back you grind the face, the smaller the
diameter will be. The reduction is dependent on the amount they have to take
off to get it sharp. To achieve a particular size, the edges would have to
be ground. That would raise the cost to the impractical.
Don't know if I would bother to send it out. But I would try touching it up
myself with an EZ Lap hone. If it's a two flute straight carbide it's
pretty easy to hone the flats.
I agree, cleaning and touch up on the flats definityly prolongs bit life.
As a machinist I am used to honing lathe tools so I also do the same to
router bits, its comparatively easy to feel when the blade of the lap is
flat on the bevel and with just a few strokes it is easy to see the effect.
Get into the habit of counting strokes so you do all surfaces evenly.
Let me see, to avoid paying less then twenty dollars you have to find
someone that sharpens carbide bits, pray they know what the hell they are
doing, get the bit too them, pay for the sharpening, then get it back again.
All for a bit that probably held up for some reasonable length of time.
Doesn't seem like a question it would take a rocket scientist to answer to
Easily found in most areas that have any manufacturing at all.
Any place that does work for machine shops. Router bits are dead easy.
>get the bit too them, pay for the sharpening, then get it back again.
That's a judgement call. I usually send mine out with the milling cutters.
I wore one down on particle board awhile back. I bought a new one for
precision work, and had the old one resharpend. I still use the old one.
The five dollar resharpening on the face worked just fine. I rounded the
corners of the bit but even that is better. So give it a shot you will
probably be surprised.
