Review on 8-Inch Bi-Metal Arbored Technology Tools by Michael Tegan

Other reviews confirm the quality of this saw. I just want to add that I was personally confused and concerned reading the descriptions of various brands of hole saws as to whether they came with an arbor (arbor shank with center drill). This one fits. I bought this to fit a large peep hole in a solid wood door and it does the job perfectly. I would advise against drilling all the way through on one side as this can split the wood on the other side. Stop when the drill first pierces the hole, then drill through the other side to finish the hole. Luckily I discovered this while drilling a practice hole in a 2x4 rather than a nice door. The saw I received has a small raised line where the metal was welded into a tube shape. I was concerned it would wobble or break, but it worked well and the hole size was within spec.
