I have had blade failure where one of the teeth has come off (I still have the sharp “23″ tooth blade made by SKIL still hanging on the wall for when I am cutting ugly scrap or OSB), the tooth was lost when cutting OSB and only maybe a total of 2 hours worth of cutting. You don’t notice until you are trying to drive the saw through wood and it requires more force than what it usually does. I’ll try the Irwin out as soon as it comes out as my circular saw is always being used.

I’m kind of with AZ_Engineer. Maybe it’s my lack of experience, but I’ve never had a blade failure. Blades get dull before they fail. Or if they fail, it’s because I abused the blade in some fashion.

Do others regularly experience blade failures in circ saws? Or table saws?

[...] Preview: Marathon WeldTec Blades Irwin’s new Marathon WeldTec circ saw blades feature welded-on teeth — as opposed to braised-on like most. We’re looking forward to getting our hands on some of them soon to try ‘em out. [...]

The blade gets hot enough for the braze bond to fail, really? Sounds like marketing hype to me. When brazing steel, you need to get it pink hot. I doubt the blade would have to get that hot, but it would certainly have to get to several hundred degrees for a braze bond to fail. Certainly hot enough to flash boil water drops on the hot blade and I’ve never seen a blade that hot.

Now if you were trying to cut steel…………………..?
