This blade is described as 3TPI (teeth per inch) but that, the one I received has 5TPI . However, I had a deadline and decided to keep it. I've been using this blade for a few weeks, so far it seems to be doing its job well. I haven't had a chance to use it for my main purpose of purchase which is to cut some 10 foot 5x5 white oak joists into 1" or 3/4" thick boards. If he can get the job done with at least 8-10 on those bars I'll happily upgrade him to five stars. For now I leave room for improvement.
