Review on 🔧 CZHS16P Piece from Cal Hawk Tools by Djkutt Kent

I bought this set because I needed a 4" hole saw and figured I could get a full set right away. There were no instructions and connecting the bit to my power tool was a bit unclear. I finally managed to assemble it and started drilling a nice 4 inch hole in the plywood. It twirled and twirled, and after a few minutes the plywood began to smoke. I looked to where the hole should have been and there was just a millimeter sized groove where the teeth had been ground down. I looked at the teeth and they were half removed. So now the hole saw has a "meth mouth" and I still don't have a hole. It's sad when a hole saw can't even cut through plywood.
