sharpening router bits

Hello, I have straight plunge router bits and I was wondering what the best way of sharpening them would be. I just purchased some diamond pads for sharpening and they say you can sharpen router bits well with this but it doesn't go so well for me. I rub the diamond pad in a back and forth motion on the carbide blade of the bit and I also first use a marker on the carbide blade of the bit to see where I am cutting and then I adjust the angle by looking at where the marker was rubbed of to cut it in the spot where I want it. This doesn't really help that much at all when I use it. It doesn't get worse but it certainly doesn't sharpen them up that much. Is there an easier way of doing this or mayby I am doing it wrong. Thanks alot.

Hello: William

Honest answer. Not possible to hand sharpen router bits. Regardless of claims made by anyone and or any tool maker, etc.

As a professional and vocational sharpener, I know this to be a fact. Unfortunately, router bits are highly specialized cutting tools that cannot be resharpened as a do-it-yourself task.

The bits, whether carbide or steel, etc. require a highly specialized, precision machine & a special size diamond edged wheels for carbide bits. White and ruby stone wheels for steel bits. Neither the machinery nor the sharpening wheels are inexpensive nor practical for non commerical useage.

Router bits have several angles not visable to the eye. Each angle must be precisely duplicated and resharpened exactly as orginal. Failure to do so will produce poor cutting results and or destroy a bit.

It's worth the costs to pay for professional sharpening. Most carbide and or steel bits can be resharpened up to about 5x's, if not overly wornout or damaged.

Sharpening costs vary, but steel bits may cost 2-3 bucks each while carbide slightly higher. Unless they are done at my place. Here we charge dearly. Time is $$$$ and bits do take time to be setup in the machine and resharpened correctly....

Router bits can be resharpened many times. Problem is it takes special machinery and special grinding wheels.

Diamond wheels for carbide and special grinding wheels for the steel bits. White and ruby stone wheels for steel bits. Neither the machinery nor the sharpening wheels are inexpensive nor practical for non commerical useage.
