Pretty good for the most part but the last rung gets kind of hard to drill through.

At the price paid, this is a ridiculous deal.I've already used several bits multiple time and had absolutely no problem with them on steel (light gauge), aluminum, plastic and wood.Not sure about longevity, but I may never find that out. If you need a comprehensive kit for semi-serious work, this is a good deal.

I bought this bit to drill out two 2 inch holes in 1/8th inch steel. Only made it thru one and a half holes. Even kept spraying it with pb blaster to try and keep it cool/lubed. Just dulled right away. I’m sure it would be fine for other materials, but not metal.

This has got a huge cutting diameter and appears to be very durable, I have only used it once, but it cut a 1' 5/8" hole in sheet metal. Make sure you have a good hold of your drill, this big of hole can be difficult to cut with a hand held drill motor.
