Topic tags/keywords: tablesaw blade dado

Does anyone know who sells a saw blade that is slightly smaller than 1/4 inch (for use with 1/4 inch plywood)? I would like to make dadoes for draw bottoms on the sides of the drawers with just one pass in the table saw. Thank you in advance.

Not sure on the saw blade, but I have a set of Rockler router bits that are sized for plywood thicknesses for grooves and dadoes.

Can you say, “wobble dado” ? That would be a pretty hefty blade, to match the thickness of the metric plywood.

Use a standard combo blade and make two passes. Doing it this way makes for a PERFECT fit.

Maybe I do scum work, but for something like a drawer bottom I will use a 1/4 dado blade. The ply it rarely dead flat, that slight bend will hold it in place. Now if I come across a situation where the 1/4” ply is structural, I will two pace it, however, I have never had that situation.

Have you thought about a small grooving plane?

I had a dado set for awhile called “The Hogger” and what it lacked
in versatility it made up in heavy dutiness. Each side blade had 1/4”
chippers and the inside chippers were 1/4” too…. so I think it could
cut from 1/4” to 1” wide in 1/16” increments – with a pretty flat

I have a cheap wobble dado head that I use. It cuts a 3/16 groove when it is at its smallest. Works for me.

I have a dado set from HF that starts at 3/16” wide also at a cabinet shop I used to work at they stacked 2 thin kerf saw blades with maybe some shimming to get the desired width, this was mounted on a dedicated tablesaw for drawer boxes

Tim, in my opinion if one goes to the trouble of making a drawer then one should use decent quality ply preferably 5 ply or even more. Better quality ply = better consistency eg in thickness. So for 1/4” ply the standard 1/4” dado set or a wobble saw are good and Neandernormite makes a valid point about straightness.
A saw blade with a 1/4” or 6mm kerf is not something I would expect to see for the usual 10 or 12 inch blades….
Maybe on a 24 inch cross cut ….
Might be an idea to check ply thicknesses before buying-someone may be selling 6mm ply and calling it 1/4” (6.35mm) ply….

Thanks everyone for your replies. I did not realize there were so many options. I like the wobble blade idea.

Have your say...
