A dado joint is a rectangular groove cut across the grain of a board into which another member is fitted. The recess runs either across the grain. So the width is determined by the size of the bit, so in Imperial terms if you wanted to put a half inch piece of wood into another piece of wood you would use a half-inch bit

Looking forward to your participation.

Thank You John

Hi Rouben, the minimum dado with is the width of the cutter.

You can cut a 10mm, 12mm, 18mm dado with 10mm cutter and a jig, but you cannot use a 10mm cutter to cut a 6mm dado.

The maximum width is set by any jig that you use with the cutter.

The smallest bit I have seen industrially available is 1/128" and 1/4" depth, coated with diamond dust, ran at 180Krevs and had a 1" shank (and yes it was used on carbide or wood); I suspicion this is not what you want. I commonly use a 1/32" x 1/4" when I restore Steamer Wardrobe Trunks and have to add drawers or rebuild the remnants of the rest of it.

Use the previous advice on dado joints if this is your first - it is good advice to learn how to make a dado by hand / also read Woodwork Joints. How they are set out, how made and where used. stock_book_yellow-16.png William Fairham (English) obtained at (FREE) Woodwork Joints: How they are Set Out, How Made and Where Used. by William Fairham - Free Ebook.

If you learn to make the joint by hand, your knowledge will guide you to the proper new technology to use, after all a table saw makes perfectly acceptable dadoes, if you have the table-saw.

Best luck - Baker

If you are cutting grooves for drawer bottoms a slot cutting bit works well when used on a router table with fence. They commonly range in size from 1/16" to 1/4" here.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

James, I have never disagreed with anything you have ever said until today. Using an adjustable fence or template, the single pass dado can be any where from 0 to 100% of the bit width. It is easy to use a 10mm bit to obtain a 6mm rabbit. A 3mm bit can be used for 6mm in 2 passes. It is the same principle as a 1/2" dado while only having a 3/4" chisel.

If I am wrong please tell me where I erred. Good luck - Baker

Richard I believe you are wrong you are confusing a rabbet with a dado a dado has two side and run cross grain (Rabbets, Dadoes and Grooves) rabbets have one side grooves run the length of the board.
In your comment to James you are talking about making rabbets,
I agree you could make a 6mm dado with a 3mm bit but how would you make a 6mm dado with a 10 mm bit

I've made dados by using a bit larger than the intended width, then gluing spacers to get the correct width. Mind you, i did not do it intentionally--and hope to NEVER do it again!!
