These work great! By Doug on 3/9/14Doug would recommend this product to a friendThese glass drills work great. I hold a wet sponge against it while drilling to keep things cool. The only time I broke anything was when trying to drill tempered glass. Don't try to drill tempered glass!
Worked perfect for my use By Ethan on 2/16/14Ethan would recommend this product to a friendI bought one 35mm & one 45mm. I made 2 cuts with the 35mm and 6 cuts with the 45mm. They made pretty clean holes and appear to have held up well - I can't tell that they've even been used.
I made my cuts with a drill press at a speedy 3100rpm and used a spray bottle with cold water to keep the glass cool and to wash away the debris as it accumulated. The glass I was drilling thru was 3/8" and 5/16" thick.
Worked like a charm. Very happy with my purchase.
Works By Greg on 2/3/14Greg would recommend this product to a friendGot the 30 mm for nano tank and the bit worked great, drilled very quickly on 10 gallon 1/8 glass tank. i didn't use a guide just started with bit on a angle and gently lifted it up to a vertical position using just the weight of the drill bit.
Diamond coated glass drill bit works great! By Doug on 1/30/14Doug would recommend this product to a friendI had never drilled glass before, only acrylic. I actually experimented and drilled a glass sump tank using a carbide grit hole saw and it worked! I ran a slow RPM with lots of water and no downward pressure. Once I tried this diamond drill bit, I was in love. No more custom ordering drilled tanks and waiting forever to get them. It works great!
Easy to Use By Steve on 1/21/14Steve would recommend this product to a friendI used the 45mm bit for two 1" bulkheads. I laid the tank on it's side, put duck tape over where I wanted to drill to help the bit "catch" and ground away! I worked so well I decided to drill a 3rd hole after the tank was standing up again!
Perfect! By Harry on 12/9/13Harry would recommend this product to a friendUsed the 3/4, 1, and 1.5 drill bits and they were easy to use and did exactly what they were supposed to do!
Cost can't be beat By Bryan on 11/29/13Bryan would recommend this product to a friendLook around on the net and you'll soon find these are the most cost effective solution out there. They are only useful for a limited number of uses, but let's face it, once our tanks are drilled the bits usually collect dust.
Works as advertised By Quinn on 11/26/13Quinn would recommend this product to a friendI was extremely nervous about drilling my nano-cube. After watching a few videos and trying it out on a piece of thin glass, purchased at Home Depot for like $4, I drilled my first hole in about 4 minutes time. Now I have drilled 5 holes in aquariums with absolute success. The one bit of advice I can give is: DO NOT APPLY ANY EXTRA PRESSURE, let the weight of the drill do the work. And yes a drill guide does help to get a nice straight start. I found one at Dixieline here in the San Diego area.
Perfect By G Hoover on 11/18/13G Hoover would recommend this product to a friendGreat price. Have drilled a total of 11 holes and have no problem. Keep water on glass and bit and works like a charm. Perfect to drill your own tank

Easy for a first timer By Nathan on 7/28/13Nathan would recommend this product to a friendI had never drilled glass and was very nervous about breaking my tank. After watching the video I knew I was ready. The bit worked like a charm. Drilled two holes, side by side, and everything went smoothly. Can't wait to drill some more.

Do these glass drill bits work for acrylic also?
Bulk Reef Supply Hey Barbara,
For acrylic you just need a plain toothed hole saw bit like the set linked below, no need for a diamond coated drill bit.

Can you drill tempered glass with the diamond bits? I have heard not....
Bulk Reef Supply Hi Daniel,
No you cannot drill tempered glass. If your glass is tempered there isn't really any modifications that can be done to it as it will shatter. Fortunately most aquariums do not use tempered glass (though its more common on the bottom panel).
