Rhino Impact Diamond Drill Bit 15mm/ 1/2" Twin Pack

I ordered this, but what was received was 17mm / 5/8". The package said 15mm / 1/2" so I received what I ordered, but not. It was either a package lable issue or product quality issue. Due to the the fact that I needed a 1/2 hole and not 5/8" this product would not work.

Used these drills to drill over 80 various bottles for a "bottle wall". Worked very well, had to use both because after about 40 bottles, the first drill was getting dull. Very helpful tool.

Good price, worked great.
