How to Sharpen the Festool Domino Cutter?

You can easily sharpen the Festool Domino cutter with a credit card diamond sharpener.

Festool is a well-known manufacturer of good quality woodworking machines and available in the United States and Europe. The brand Festool has become a bit of a cult and in some circles wields tool snobbery. 

It is undeniable that this German brand Festool has earned its place as top quality.

Why not just buy another Festool cutter?

At fifty euro each for a Festool Domino cutter, it makes sense to sharpen these tungsten carbide bits, and why wouldn’t you. 

The sharpening of these cutters is actually very simple but first, you need to understand how they work.

Ok, then let’s delve straight into the cutter bit ethos. The Domino Dowel does not have a traditional cutter profile. Not every machined edge makes contact with the workpiece. This simplifies things somewhat. 

My Video on sharpening the Festool carbide cutter

In this video I demonstrate how I sharpen my domino carbide cutters. You too could save money by sharpening your own cutters. It is good to regularly sharpen the Festool cutter so they do not overheat. A sharp Festool cutter will speed up your workflow. The Festool Domino DF700 XL is featured in this video. You can also sharpen the Festtol Domino DF500 but the cutters are smaller and can be tricky to sharpen. It is still possible to sharpen the cuitters of the Festool domino DF 500.

Where do we sharpen?

So If the cutter has an unconventional cutter profile then, where do I sharpen? That is a good question. You only need to sharpen the cutting surfaces.

This image shows the cutting edge of the Festool domino cutter.

What we have to acknowledge is that the Festool Domino dowel cutter only cuts on the premier contact edges. What I mean by that is that the cutter only cuts on the tip of the tool.

Well, it is simples, just take the easy route and put an edge on the tip. The Festool cutter cuts with the machined edges. 

I repeat, So where do Sharpen?

Place the Domino cutter in a vice or find another way to secure it. 

Take a Trend or DMT Diamond sharpener and make a few swipes with those angular edges. This is the ad-hoc method of Sharpening a  Festool cutter.

These DMT credit card sharpeners work really well

Should I use a Jig to sharpen the Festool Domino Cutter?

Personally, I feel that the process of sharpening the Festool domino cutter would be a lot easier and more accurate with the use of a jig.  At the time of writing this article, I know of no commercially available jigs for the purpose of sharpening a festival domino cutter.

This does not mean it is not possible but you will need to use your imagination.  I am in the process of making a jig for this sharpening task. A simple method of holding the cutter rigid and a guide to assist the diamond sharpener to make accurate passes should suffice.  You might find my last few years experiences with the Festool domino interesting  

In Conclusion, should I bother sharpening Domino Cutters?

I have been sharpening my cutters for just over Four years and I don’t see any reason why you shouldn’t consider doing the same. When cutters cost around 50e it makes sense to sharpen them and also sometimes they need sharpening during a prioject when you have no spares!

Malcolm the Boat ‘RIP’

Woodworking for me is in my blood as a son of a traditional boatbuilder. My Father Malcolm Kett was highly skilled and inventive individual often referred to as ‘Malcolm The Boat’.

Marcus Kett and my Mortar!

Although I have spent a considerable portion of my life seeking further education and gaining qualifications in woodworking, electrical installations, bricklaying and to top it a degree in photography.

Yes, it is a medley of possible career choices but the one that I felt truly at home with was Woodworking. Woodworking has been my staple career choice that has given my family stability.

Why do I write these guides?

Well that’s Me

We started to write these guides to help our customers. The idea was to provide the information needed to install our made to measure wooden products that we sell on this website and directly to our local customers.

We soon received feedback from people abroad and interested readers not local to us. I like to help people and I am excited that fellow woodworkers or keen DIYers found guidance in my articles. I intend to carry on writing and producing youtube videos for the purpose of providing useful content. Please share our blog with your friends and anyone that could find interest in the magic of working with wood.

How did we come up with the trading name ‘Wallybois’? Well, it is simple really, my best buddy ‘Wally’ and the fact that ‘Bois’ is French for wood and we live in France.
