However, my last project involved making about 24 raised panels from MDF. This left my raised panel bit in very dull condition. I have tried sharpening it by using a set of diamond sharpening tools (the cheap flat ones) using 400, 600 and 1200 grits. I probably spent well over two hours on this, but although it came out sharper than when it started, it is nowhere near the razor sharp condition I was used to. Of course, I didn't know exactly how to do it - just tried to follow the original angles.
Anyhow, has anyone tried to do this or is there a professional sharpening service that could do it or should I just figure that I got my money's worth & buy a new one? I think I paid around $75 for the bit.
By the way the coping set which I used only on oak & poplar has been holding up much better.
Any help/advice would be appreciated.
