Good hole saw it did the hole so easy on the porcelain tile in a blink of an eye, however it will be good if they added the bit so it can guide it because it was a really dificult to keep it on the center of the mark every time I try to drill it was spinning all over the tile until I try sideway , even if it cost a little more that is a must needed. But other than that what a piece tool this is!! Great!

Cut through tile like butter, I found that the bit liked to skip around on the tile so after making a hole in 1 tile i put that on top of the tile I wanted to cut and used it as a guide. Worked great!

I have been needing to get a 1 3/8" core drill to make a new hole in my kitchen countertops, which are solid granite. This diamond hole saw was just the thing for this purpose.This particular core drill/hole saw got my attention because I could simply thread it onto my angle grinder's threaded shaft directly; making it really easy to use. No mandrel required! That was a money saver to start with. It also makes it a versatile tool, since it also comes with a mandrel that allows you to use it with a drill. That gives you some power and speed options, between an angle grinder and a drill. The diamond cutting area held up well during use on the granite, with no observed loss of the diamonds after my cut. I did use water to help cool it; I just used a spray bottle set on stream to keep water in the cut for cooling and to help get the dust out of the way.Overall, a good quality tool; a solid value at its price point.My Rating System -Five Stars - Better than I expected; exceeded expectations.Four Stars - Met expectations; exactly what I expected.Three Stars - Average quality; nothing fancy and not quite what I expected.Two Stars - Noticeably below average; disappointed.One Star - Absolutely below expectations; not worth my time or yours.Since ratings are opinions, they vary as much as the authors that wrote them. I try to be fair with mine; if I’m not certain I will tend to give the better rating of what I am contemplating. I will describe the item as best I can from my perspective, giving what detail I think matters and try to give an accurate description as I see it. Hopefully, the review helps you.
