A couple years ago I bought a 2 pack of DeWalt 10" 80 tooth blades. I've worn them both out cutting aluminum, but I can't complain. They did a really good job and made a lot of cuts over the last couple years. I still have one in my table saw, but its at that point where I know its going to turn dangerous on any cut now.
I've tried a couple other blades, but I kept going back to these until they just broke too many teeth to use. The one on the saw now is still cutting ok, and its only lost one tooth, but its got a couple teeth that will chip weld pretty quick now. That's when the blade gets dangerous and will grab a piece of metal instead of cutting it.
Anyway, last time I looked those blade packs weren't available in the local stores anymore. What other surprise quality blades might be out there to look for?
Somebody gave me some HF blades and they were a joke. Stripped half the teeth on the first cut, and chipped most of the rest. Some of the stripped teeth came out clean, and some took part of the blade with them. Never saw a blade come apart so fast and so thoroughly before.
