Prevent Burning End Grain When Using A Router

The whole time you’re routing the sides of your board, everything is going great. Then you get to the end, and suddenly the wood is burning!

It’s common sense that wood will burn if it gets too hot. The heat is caused by the friction between the tool and the particles of the wood. Sometimes this seems inevitable. But there are a few things you can do to ensure that this end burning never happens again.

The most important thing to do is make sure the end of your router bit is clean. Pitches on the blade increase the friction between the bit and the wood. Increased friction means a hotter wood that is likely to burn.

You also need to make sure that your bit is sharp. A sharp edge will slice right through the wood fibers, whereas a dull edge mangles everything.

Also, the faster your route across your board, the less likely you are to create long-term friction. Just don’t do it so quickly that you mess up and make cuts here and there. While you may think that routing the board slower will give you a better cut, but there is a huge difference between a cut that looks clean and one that actually feels clean.

Cut offs complete.

Want to make many cuts at the same point? Feed your work-piece slowly into the bit. Doing so will create a vast amount of heat in your project. This is because the cutter is rubbing the wood and not actually cutting it.

If all else fails, reduce the speed of your cutter. This will reduce the amount of contact between your bit and the wood you’re routing. This in turn also reduces the amount of heat, which means a lower chance of burning over time when you’re working with your pieces.
