For some reason that I will likely find out after the fact, my wife bought me a Festool Domino set, it will arrive tomorrow. I see that it comes with the 5mm cutter, the project i’m working on right now is a coffee table, I’ll be attaching a ~3/4” thick apron to ~1 3/4 square legs. Would the 5mm dominos be appropriate for this joint, or would i need to go straight out and get the 8mm cutter?

A lot of guys stick with the 5 MM cutter and the tenons are plenty strong. I think I’d go ahead and get the 8MM, don’t forget to get the tenons as well. There are aftermarket cutters now that are a lot cheaper, CMT offers them, and it seems like I read they make the OEM ones for Festool as well.

I would get the Assortment Systainer (#498899) which includes 4, 5, 6, 8, and 10mm bits and a good assortment of dominoes.

I have it and it’s a great start to see what sizes you need. Only having the 5mm bit will really limit you projects.

She does have a sister, but they’re both trouble. Are the dominos LOTS cheaper by the sustainer full? Are there some sizes tab just seem to sit around and not get used? That sustainer comes with a bunch of cutters right?

If my wife sprang for a Domino, after I got up off the floor after fainting, I would make anything she wanted.

This was, I think, a stealth gloat. There is a big ‘you suck’ somewhere around here.

Have fun!

For your project, the 5mm dominoes will be fine. (I usually use 6mm for 3/4 stock, but 5mm will work fine)—but I would definitely get the assorted bits and dominoes. I use all the sizes. The Domino is like a dream come true for making M&T joints quick, easy, and accurate. You’ll love it!!

The 5mm would be fine if you don’t want to buy more cutters at this point as it’s a good size for 3/4” stock which is about 19mm in thickness. What makes the domino systainer set a good deal is the bits and the box. If you already own the other bits and don’t need a good place to store the dominos you are better off just buying them by the bag.

That’s called a win win and you’re wise to purchase the accessory systainer.

You can also attach the top to the apron with the dominos, elongate the apron and
domino it to the top.

We often use festool dominoes in our structural work. In fact, there’s a reclaimed maple landing in the Warner music building in Manhattan, that was repaired using 610 structural epoxy & 8mm dominoes. Pretty sure that sucker ain’t goig anywhere for a good long time.

Domino’s are pretty much the same price for everyone. Buying the systainer with Domino’s can be a plus or minus as you may never need all the different sizes….Jack

This is the first thing I’m using the Domino on, just the frame. It was pretty easy to figure out, couple joints were not perfectly tight but I think I know why. Awesome tool. This is a dry fit, no finish on frame yet

You should have a gap about a 1/16 -1/8 gap split between the two pieces. Double check this each time you use it on different domino’s…

Usually I will put the domino in the first practice piece(mark it) to make sure more than half the domino goes in and put the other end in and mark it. With the two marks you’ll see your gap..
