Excellent saw blades. I bought another brand and broke 3 blades in half an hour. Put on a DeWalt blade and an hour later it's still cutting. Cutting chain link posts.
So far so good. I cut 80 gauge steel tubing, a 1/4 plate and some thick aluminum. Nothing has given them any problems so far. Finished cuts are fairly smooth and burrs are minimal.
When I use them at the lowest settings I still shoot them in about 10 cuts. I cut a 3/8 steel rod on it which might be part of the problem but I was expecting more since they come in a pipe cutting tool.
Swearing with a blade for a long time and still holding on. Although only slightly more expensive than cheap blades, this one lasts at least three times longer. I will continue to buy them.

These blades suck. You wouldn't get any stars if I could. I hadn't made half a dozen cuts when the first blade began to dull. After a few moments it broke at the weld when I tried to tilt it a bit. I was then able to bend the blade without breaking it. I cut annealed steel. The blade that came with my Wen portable band saw lasted longer than all three combined.
The blades cut well because the teeth are very hard (65 HRC). However, hardness will lead to tooth loss if you choose the wrong TPI for your application. I was guilty of this for a while and chewed those blades like crazy. Now I'm using 18 dpi, which is better for my typical material thickness. The blades tire. I usually replace them for fatigue cracks and fractures, not tooth wear. You may need to find a band saw welder. Generally good quality from Dewalt. Will keep buying.
