I used the search button but could not find the answer. I have a 10” benchtop table saw and was wondering if it can be fitted for a dado blade? I plan on getting a new saw in the future, but for now, this is what I have.

Probably. The length of the arbor may limit how many blades/chippers can be used.

It can most likely handle up to a 1/2” wide, 6” diameter dado, thats pretty typical for a benchtop i believe

Maybe a wobbler or Twin cutter. Even if a full stack fit, it may not have the “oomph” to run it ( for long).

I started out with a small craftsman we paid 150.00 for brand new. I could get up to 1/2” on it but I would just run 3/8” on it because then I could just make two passes to get a full 3/4” cut. It was serviceable for me at that time and we built some really nice items with that small saw. I look back and realize how dangerous the saw was because of the potential for it to tip over.

Also, we ran a 8” dado blade on our small saw and seemed to do just fine stacked to 3/8”.

Table saws designed to run on common household 120V circuits are considered “underpowered” by blade manufacturers. For this type of saw I would recommend a 6” stacked dado set as this will give you more cutting torque. This will become more important as you cut wider and wider dados.

You will also need to find a saw that has a dado table insert available. Otherwise you are limited to the width of the saw blade insert.

I’d seriously consider using a router. You can make a simple jig that makes super accurate dadoes much more safer than you can on an underpowered saw.

You want to check this out carefully. Some of the benchtops don’t have arbors long enough to safely accomodate a dado cutter of any type. Two examples are the Craftsman and the small Ryobi (BT30?). My brother has the Craftsman and I have the Ryobi for my jobsite saw. My brother has a little DeWalt wobbler that does an ok job on dados , but is a PITA to get set up right, and won’t do 3/4” dados.

Take the blade out of your saw, run the nut all the way on, and measure the amount of exposed threads left on your arbor. That’s the maximum thickness of your dado cutter – either wobbler or stacked.

Thanks everyone for your help. I think a 1/2 inch wide dado would be good enough for now. How do the wobbler dado’s work? Are they any good for cutting dado’s? How are they cost wise compared to a stacked dado? Sorry for so many questions, I know next to nothing about dado blades.

thanks in advance Rich

The wobble blade dado blades has a center adjustment that allows you to change the width of the cut ,I think up to 7/8” .The bottom of the dados made by a wobble blade tends to be somewhat rounded compared to a stacked dado. The wobble blades I think start around $59.

I used a wobble dado for a while and was never satisfied with the performance. Jim is correct, the bottom was never flat and getting a precise fit was next to impossible.

Another thing to consider is whether that insert for the table ( that removable thingee that the blade comes through) has enough room, or has a dado insert. Like the guy up there had a craftsman “contractor” ( bench model on a stand) for a couple years and I could do 1/2” dados, occasionally tripped the breaker on the saw. Craftsman has those alot, just meant slower feed rate.
Good luck

Freud makes an adjustable dado that cuts a flat bottom dado, but it’ll lighten the wallet pretty quick.

I think this is it, but it looks pretty fat , arbor wise.

I think lumberjocks voted the wobbler the worst woodwork gimmick of all time a couple years ago :)
