"I tested a 7/8” and 3” hole cutter on both steel and aluminum. Both surfaces were old concrete chutes off of mixer trucks, which were a little thicker than an eighth of an inch. First off, the tool itself is great quality, from the carbide hole cutter itself to the pilot bit and spring, it’s a very well built tool. Cutting through both the aluminum and steel were super easy taking less than 30 seconds a cut. It really cut through the aluminum like butter. The pilot bit is great and I didn’t even punch a starter hole to get it started. The spring ejects the cut out piece upon completion of the hole like magic. It really is a high quality, well thought out tool.\r\n\r\nThe shank on the 3” hole saw will not fit in a 3/8” drill, it has to be a half inch. Other than that i didn’t notice any difference between the two different sizes. Both of them come with an allen wrench to remove the pilot bit and spring and both of them have stop shoulder which limits cuts to 3/16” depth. If you’re trying to go deeper than that, this isn’t the hole saw for you."
