If you want super sharp result continuously then sharpening router bits is essential as the best wood router bit is essential for your workpiece. The hand tool, router bits don’t require shaping on daily basis. But fairy is requires reshaping as your working criteria. If you often work with your router bits you should once in a week.

While you working with chisel or hand planes, you have to stop fairly often for a quick round for sharpening again and again. Usually, good quality carbide can be expected to hold an edge perhaps twenty to thirty times longer than took steel. So it should be clear that sharpening is going to on a regular basis. A carbide-tipped router bit can perform the same if you share it once in a week as like a good chisel with twenty times of shaping.

Sharpening Router Bits

Sharpening router bits is an easy procedure. For that, you don’t need a shaping jig, precision measuring instruments or any, other complex machinery. You just need some diamond paddles or diamond tile saw blade. Or the diamond needle files for the smallest bits; a good light source etc. there is no fussy finger work requires this job because you are only going to work on the flat radial face of each flute.

But it’s important to sharpen uniformly so the bit will remain balanced and cut well. Not the working on single flute until its sharp the go for the next one. You can ensure an even job simply by giving one flute five else ten strokes rotating the bit and giving the next flute the same number of strokes and that previous step.

How to sharpening router bits

You will need a diamond wheel for sharpening carbide cutters. You can use a diamond tile saw blade instead of the diamond wheel. Because a diamond wheel is quite expensive. Buts the diamond tile saw blade done the job but quite rough in finish. But you can try a dermal tool with a diamond wheel to sharpening carbide saw blade for smoother performance. It’s quite cheaper compare and works well.

First, you have to sharpen the flat part of the cutter and then sharp the outside edge. For round over bits and other bits with inside curves a wheel really would not work so well. Look careful at each edge you are working.

You may want to complete it with unmistakably clear or putting more pressure in one place than another to sharp with clear but still, there is a possibility to left some spots. It’s obvious so doesn’t be so surprised. If it’s your first time it might take some tea time and work out to lap each flute entirely slate. It’s better t work with fine or extra fine 600/1200 grit diamond abrasives.

You will feel once it sharps enough. Just look at the router bit observe under a strong light your vision will answer once it sharp enough. But if your bit needs more work to do than these can provide it probably should be sent out professional help. Usually sharpening router bits done just in one to two sessions at your personal workshop.
