Awesome! Review by James
At first I was very leery of drilling my own holes in my tank. I had just spent almost a year custom building a stand for my 72 gallon bow-front. It already had the holes drilled for the over flow but I needed the hole drilled for the return. I delayed and delayed drilling the hole. Worried that I would shatter the glass, ruining the tank. Especially since I had spent over a thousand dollars on the stand. But I took the plunge and I bought a used tank with the same glass thickness and used it to practice on. I bought the 1.5" drill bit, made a template to keep the bit centered and set up the garden hose to lube the bit and keep it cool, just like the guy at AquaCave told me. After the fourth hole I had more than enough confidence to drill my tank. Worked like a charm. It was one of the best investments I have made so far in my hobby. Thanks guys! (Posted on 7/31/2014)
Pleasantly Surprised Review by Brian
Typically diamond cutting blades and bits are extremely expensive; so I was rather hesitant purchasing this bit. I used it to cut through a 3/8" piece of glass in my sump. Using a drill press and a constant flow of water; it cut through the glass with ease; and still has plenty of life left for multiple more cuts. So long as you have a constant speed and water; you'll have no problem using this bit. (Posted on 4/3/2011)
