Review on 🔩 ZXHAO Bi Metal Toothed Drill Bit for Optimal Drilling by David Thomley

Had to cut a hole in the tub panel for a valve. I only needed to make one cut, so I didn't need a strong one, but I did need a safe and precise one. That was excellent. The hole is true to size and well cut. I don't know how it will behave in wood, but everything was fine in the acrylic edge of the bathtub. I already had a smaller diameter hole saw with a central hub with locking pins, so I used that in place of the hub that came with the kit. these (without locking pins). The supplied socket would probably be fine, but I felt more comfortable with a socket with locking pins. This hole saw came with universal holes for other brands of center hubs so it was nice to have that option.
