Good day, I need some help with cutting the top of my box. I will use my table saw. My question is which blade do I use, a 24 tooth rip or a 80 tooth crosscut or some other blade.
Thanks for the help!!

I would go with the rip blade. That is, of course, provided your grain is running horizontally, or parallel to the top and bottom of the box.

wont matter because you will likely need to do a bit of sanding anyway.
However start on a short end and work your way around so that you are making a long cut last
Some will put a 1/8th shim at the top with a piece of masking tape – but that more depends on the shape of the box and how stable it is.

Though I tune the fence alignment – I always need to sand the box lid to remove a little ledge from one of the corners, as there will be a little spring to the box lid as you cut it free that can push you away from the fence just a smidge.

To Sand it all back flat I usually use doublestick tape on the sandpaperpaper on the wing of the table saw.

Another good tip (not mine) is to make your cut approximately 1/64” short of the full thickness of your box sides. This will eliminate the need for shims. After you have cut all four sides you can use a razor blade to cut through the remaining wood.

MisterBill’s technique is much safer and less likely to ruin your box than making full thickness cuts.

I have also used the same method as MisterBill..It is a time proven and accurate method. i also would put some tape where the outside cut will be to help avoid splintering.

I build a LOT of boxes and cut the tops off in my band saw.

I cut mine like Mister Bill, too.

Then I put a full sheet of sandpaper on a table with doubleback tape. I sand all four edges of the box and the lid with a rotary motion of my hands. Works great and insures you don’t sand too much on one edge and make a gap when the lid is on.

Since boxes are generally half an inch or less in thickness, a good combo blade works as well as a rip blade.

Another vote for Mister Bill’s method.
Especially if your saw does not have a riving knife.

Thanks again for all the information!! Now I can not only cut a box lid off but I can be safe doing it.
