These worked so well. Actually, these work better than my expensive name branded set I had a few years ago. The attachment system is so quick, easy and secure. Blades cut nicely and drill bit is very straight.

This is indeed an impressive hole saw kit. More than twice as many bits as the set I have replaced with these. There are a few things that stand out with this set that makes it well worth the cost. First and most important is the very unique design they have used in order to secure the hole saw bits to the drill bit and housing which keeps them spinning throughout the entire drilling process. This addresses the biggest issue I had had with my old set. When the bit would start to bind it would jump off the drill and I would have to re-tighten it to continue. With this set there are steel pins that protrude through the bottom of the bit which makes it impossible to spin out and hence pushes through the hole every single time. Second was the height of the teeth. They are longer and more aggressive than any bits I have used. Lastly is the selection of sizes. You will probably use only about four or five of these sizes consistently, but it is nice to have the others when needed. A great heavy duty set, much better than my old Craftsman set I had and about half the cost. I do recommend this set and if you register the tool, company will DOUIBLE the length of your warranty.

So the kit looks nice. Box is nice. But I just used this for the very FIRST TIME. I used my 1 3/4 hole saw on some aluminum, and it snagged.... 3 teeth broke off, AND the drill bit snapped. So I'm not sure if this is a great product. Seems the metal quality may be lacking. I'll post an update after more use.
