Review on QLOUNI Concrete Cement Cutter Connector by Desmin Dickerson

I bought this hole saw to make a curb cut for a French drain. I was hoping it would hold an inch of cut so I could have a clean look and expected to have to use a ton of smaller holes and a jackhammer to complete the cut. It survived the initial pruning well. I then decided to drill some 1/4" drain holes around the perimeter and some 5/8" holes in the center to drain the sump on the other side of the curb. This had the added benefit of supplying cooling and flushing water to the saw. It took about an hour of drilling and punching to fully penetrate the 4-5 inch thick concrete, but in the end it looked like it would wear just as well. I would give it 5 stars but the pilot bit had significant wobble (I removed that after the 1/4" trim) and the bit was a bit wobbly. Overall it has still performed well and is exceptional value.
