Depending on the size of the box joint and your tolerance for tedious work a rip blade will do it. Obviously if your need is larger than a single kerf it would require multiple passes and that is where the tediousness comes in :)

Not sure what your idea of “value” is but I have a neighbor that uses a 6” freud dado set that would work fine for box joints looks like Rocker has them for just under $90.

My father uses an Oshlun which is in also in that price range, they also have a box joint set for around $60 but then you can’t use it for the varying widths you can with a dado set.

I currently use a 8” freud dado that I got because someone returned it to a store without ever having put it on their saw but the store wouldn’t sell it as new anymore so I got lucky.

I don’t have any personal experience with the lower cost dado’s that are out there just what I have heard others complain about…

I make a fair number of boxes with box joints. All 3 of my dado sets (Amana, CMT Orange, Oshlun) leave slight bat ears, not desirable in a box. Router would be my first choice, but absent a router table i’d be real tempted to try that Oshlun box joint set. Carbide Processors had it marked down a little earlier this week—and I almost bought it then. The Oshlun dado set I have is a very good set in my opinion, especially for the money.

Unless you’re willing to square the cuts, a flat tooth grind is the minimum starting point. But by the time I get decent FTG, i’d be at least in the neighborhood of the Oshlun box set which will give consistent 1/4” and 3/8” slots with flat bottoms.

Value? Depends on what your time and patience is worth.

Have used many things to make box joints: cheap rip blade(many cuts), router bits, Box joint blade (Freud, Oshlun, & Forest make them), and Dado blade. FTG Rip blade is cheapest entry point, followed by router bit; unless you find a used deal on dado/box blade.

After I picked up a Freud box joint blade at garage saw for $25 a few years ago, have never used anything else. Dedicated box joint blade is super easy to use, no adjustment shims required like with universal dado blade, and cuts square edge in plywood with no splintering. Once I had one, can say that is worth spending $60-70 (sale prices) on dedicated box joint blade, if you are going to make boxes on a regular basis. YMMV

Unless you want to do it with a saw blade (the many cuts thing) those sets all seem to be around $100 (or more). That is, except for the Oshlun set. I have a couple of Oshlun blades and consider them to be high qua;ity, and i see Carbide Processors sells the box joint Oshlun set for $55…..if’n I was in the market with your criteria it’s the set would look at.
