Dado stack with only the 2 outer pieces.

most dado stacks are 6.4mm with the two plates.

Have never really thought about it as the number of times where i needed a 6mm kerf I've either gone with the 6.4mm dado kerf and left it at that or made two passes. If its not something you're doing regularly might be an option.

Alternatively you might have better luck with using a router bit? or router plane/multiplane

Those have conical teeth, you won't get a square groove with them.

Here's one ̶y̶̶o̶̶u̶̶ ̶̶c̶̶o̶̶u̶̶l̶̶d̶̶ ̶̶h̶̶a̶̶v̶̶e̶̶ ̶̶r̶̶e̶̶-̶̶g̶̶r̶̶o̶̶u̶̶n̶̶d̶̶ ̶̶t̶̶o̶̶ ̶̶6̶̶m̶̶m̶̶,̶̶ ̶̶n̶̶o̶̶t̶̶ ̶̶c̶̶h̶̶e̶̶a̶̶p̶̶ ̶̶t̶̶h̶̶o̶̶u̶̶g̶̶h̶ https://www.timbecon.com.au/sawing/c...dado-saw-blade

You're looking for a fairly specialised tool, expect to pay for the privilege. If you could use a 5" or 6" diameter moulder blade you'd have no trouble finding one.

EDIT: no need to re-grind

Well I found that Timbecon were selling them as 6mm blades here, but look at the cost!! The sales guy swore it was a 6mm blade despite 6.4mm being written on the blade itself by the manufacturer. And the sales guy wanted $46 postage from Melbourne to Townsville !!! Well that's not happening !

Went online to see what the calculated postage would be - $20

will check out my old Dado set

From the site "Offered in a metric 6.0mm kerf"

EDIT: Also, $130 for a special blade is downright cheap in my books. I don't know what you were expecting/hoping to pay for it, but I certainly don't think it's a bad deal.

well, I might have been a bit hasty, elanjacobs. I initially got the impression that the sales guy didn't have a clue with the ridiculous postage and the size of the kerf written on the blade in the web page that was in contrast with the 6mm written elsewhere

Assuming that you want to use the blade for a dado or cutting box joints.
I think that it was Freud that offered a box joint blade set at one time. IIRC you put the blades in L-R and got ¼ or when R-L you got 3/8 kerfs. Us Luddites here in the US still use Imperial but in Metric it translates to 6.35 and 9.525 MM respectively.

Apparently Freud no longer manufactures the set but you may find some in old stock.

Another solution might be a rip blade (Flat top grind or raker as the luddites call it) and then a pass with a 6 MM router bit. The rip blade will make the 6 MM cut easier as half the material will be removed.

I've been using a Freud as a mini dado blade for years. Not sure if it is 5mm or 6mm but it is thick.

You can get Freud box joint blades that are flat topped and will do a 1/4" kerf.

Edit: this is the same one rrich mentions. $100 from Amazon US shipped to your door.

A bit off topic and apologies to the OP.

That Freud blade is lovely but they seem to come only in a 5/8 arbor size, my Harvey tablesaw has a 30mm arbor unfortunately. Is 30mm a common size in AU or is it a NZ thing?

Timbecon in Melbourne have such a blade. I have one and it is great for dados and grooves.

Most saw blade sharpening companies can change the arbor size for you. I did that with my dado stack after I purchased my Harvey saw as well. Cheeper than finding a 250mm dado stack with a 30mm arbor

30mm is industry standard for larger machines
