Review on HSS Deepcut Holesaw - 1-3/8 Inch (38mm) by Sri Mims

For cutting holes in finished plywood for wire routing. The teeth are so aggressive that they can (and do) snap around (hand drill) and mess up some parts. I suggest you run it backwards at high speed and with some pressure to create a little groove so it doesn't bounce around. Once you do that, it will work fine with fine details.
