I have no complaints about this band saw and these blades have been around for decades. I have bought blades with finer teeth for cutting stainless steel. I usually stick with 18 TPI for general metal work.
Being a Milwaukee product, I expected more. These blades are brittle and will break or dull too quickly. I never expected a Harbor Freight product to truly outperform a brand like Milwaukee. I will not buy these again.
While it _technically_ fits the Harbor Freight portable band saw, it doesn't seem like it's going to be there. It cuts naturally, but quite shakily. The seam (weld) between the two halves is clearly visible and in the cutting area the whole saw wobbles. The blade that came with it from HF was fine, so I don't know why the Milwaukee is so bad.
