Great for my needs Review by HK
I purchased this to drill holes in the bottom of large vintage glass jugs to make pendant lights. I realize that this probably isn't what most people are purchasing this item for on this site, but for my purposes, this hole saw worked great, and the bottom line is that it cuts through glass well. the hole saw made it through 3 jug bottoms but did start to slow down slightly near the end. Given the previous review, i anticipated this, though. I did crack one jug, but I think this was because I had the drill on too high of a speed. overall, highly recommended, as this is the cheapest that I've been able to find a hole saw with this diameter and it got the job done well.

Good for the first hole Review by Lang
Pros - easy to use, does as advertised.
Cons - Used this to drill two holes in 3/8" glass. The first hole took about 10 minutes, the second took over an hour. This bit is good for 1 hole, terrible for 2, and I would not even attempt a 3rd. (Posted on 3/11/2011)
