Default Plywood/dado router-bit question

I'm building a simple piece for my shop out of CDX plywood, which is just under 3/4" thick. I want to use dados for some of the joints, but my 3/4" router bit will cut the dado just a hair too big, leaving me with a sloppy joint.

I've read that there are special router bits for undersized plywood. I don't want to spend much money on these bits. Any suggestions? I know 3/4" plywood thicknesses can vary quite a bit.

I believe you can find exactly what you are looking for at Holbren which is one of our sponser's. Here is the link:

I ordered this set and have been very happy with them and they do not break the bank either

You can use a smaller bit,move the fence and make another pass.

I have found them to be quite satisfactory. When I ordered I purchased 2 sets (I believe they had some kind of special or was trying to balance the freight... can't remember for sure), but for the money they are a good value IMHO.

Cheers

I have this set....ordered when starting some cabinets for the wifes laundry room....was a bit skeptical at first but for cabinet grade, sanded both sides plywood...these bits work great...fit was so good hardly needed glue....of course I did glue them on final assembly


one thing I did do....I very slightly sanded the edge that is inserted into the dado...just enough to get rid of the "fuzz" ....making assembly much easier...

dunno how these bits would hold up under production use....but for the home shop they should do you quite nice...

If you have quite a few inches of dado to do, pop for the "plywood bit". Its easier than screwing with a jig. Been there, done that.

Yeah -- I just want to be able to clamp a straight-edge to the plywood and run my router against it.
