Bcassel, I bought the Lenox blade at a local industrial supply. It was the only one they had. I went to this size because the 1/2 inch blades were breaking. This one is 1" x 12" it has 14 teeth. To be honest I did not like it. I found that the teeth were just too coarse and I felt it was beating the saw to death. I ended out using a 1/2" x 12" with 18 teeth, much better. Oh, they are bi-metal and say they are unbreakable.
Now here is the problem I have no idea where I bought them. It could be Home Depot, Lowes or Harbor Freight they are all local to me. If I remember I'll check the name brand.
I know that Enco sells Starrett blades you can also check with Mc master Carr or MSC.
Hope this help's you.
Paul
