A few months ago I bought a used 14 inch Delta band saw that came with a variety of Olson blades which I thought were sharp. Even after adjusting the saw several times and changing blades and guides, all of the Olson blades drifted horribly and the saw performed horribly. I thought it was a problem with the saw so I just avoided it for a while. Enter this Powertec saw blade. I bought this saw blade on a whim (for less than ten bucks, why not?) and it's like a brand new saw. It now has minimal (if any) drift and runs like new. It cuts through an 8 inch oak log like a hot knife through butter. Highly recommended.
