This is a coarse blade with a VERY wide kerf due to the tooth angle. I've used it to cut 4โณ thick hard oak on a regular, tiny, cheap 10โณ band saw from the 1980's. It works, but the cut is huge. I don't know how long this blade will last. I've cut several (probably 10) 4" boards with it and it's still sharp, but I'm not entirely sure about the quality of the blade. I have a dumb, powerful 24" circular saw that I fucking abuse), these cheap saw blades are probably an acceptable solution for meโฆ
