The worst bits I have ever seen. Every single one the whole bit would wobble because the shaft was not straight. The suction cup jig is completely useless as it is not flat so if any pressure goes on it it tilts it and pops off the tile.Just buy a bit with a center piece so it keeps it in place vs this.

the hole saws all put in one plastic bag. did no do the diamond cutting medium any favors the inside of the bag was covered in diamond dust so mounted the holesaws in a board to keep them from wearing the diamond medium off. put it all back in the original box for storage.this indicates that the mfg has little to no quality control. the sizes of the holes made is barely within tolerance. no sizes on the holesaws themselves.aside from this the hole made in the glass bottle was adequate.

It was good not great. The bit wore out a little too fast but not horribly. The suction cup was a little below expectations and didn’t hold as well as I would have expected.

I buy crap from Amazon almost daily it feels like and I NEVER right reviews, but I just had to for this. I am a solid DIYer. I've struggled with hole bits many times over the years and never have I had the easy, quickness and success this pack has given me! The pictures above were taken off the very first attempt at using this kit. As you can see, PERFECTION!! Can't say enough about it. Need to make some holes in something, get these!!

I’ve been using this item on Stained glass (art glass). Results were very good.I used a drill press with a water bath covering the cutting area.This has been a great addition to my glass studio.
