Awesome! What blades are cheaper that work "just as good"? Please tell us what to look for.
Most older table saws were 8 inch not 7 1/4. 7 1/4 is a portable hand held circular saw size not a table saw size. Nobody makes 7 1/2 inch blades as far as I know.
It was late at night and I did mean 7 1/4 saw blade. Unluckily for users of blades larger than 10 inches there is not much of choice. But for the users of saws that use 10 inch blades we do have some great and not so costly choices.
After years of wood working (hobby) I've have these few facts. If the saw blade does not sing, that is run smoothly with out any side to side movement (no vibrations and no run out), you have a junk blade return it if it's new. You will get a smoother cut with more teeth but there is a point of diminishing returns (depth of cut and if it is a rip). Also use thin Kerf saw blades it does make a difference in waste if you going to cut many small parts out of a large piece of wood. Another benefit is that it takes less power to make the cut.
I have three Ridgid 10" saw blades (2 - 50 tooth combination and 90 tooth combination) and one Hitachi 40 tooth combination. Both brands are laser cut and just sing (no vibration just the sound of the teeth cutting the air is all you heard) All cut the wood smooth. I have the 90 tooth on the compound miter saw and the cuts are glass smooth. The Ridgid cost me about $70.00 USA for the 90 tooth and the 50 tooth's where in the $50.00 range, the Hitachi was the cheapest at $32.00. I have two DEWALT saw blades, they are on my junk blade pile, they do make nice tools but not nice saw blades (too much run out) OK for framing not good for cabinet making.
I have about a dozen other saw blades but most of them I got when I got the saw. Most will just sit there not being used as they are not carbide blades. But the carbide blades that are there do not sing, and they also don't cut smooth either. I use them if I have to cut metals or junk wood that may have steel in it (nails or screws).
