Quality Bit, Chewing Through 0.25 Inch Glass By Greg J on 3/5/2013

I ordered two of the 45 mm bits with a total of 5 holes to drill, i figured "better safe than sorry", i'm happy to report that with a slow drill speed and constant water flow, these bits will last, even in thick glass. These may be a dollar or two more than other places, but it's so convenient to get the bulkheads and the hole saws in the same box with one shipping charge.
Will buy again.

The product was very economical and a high quality product. Perfect for DIY'rs. Alternative bits from other online suppliers are far more expensive for the same quality. I have seen the bits as high as 65.00 a bit at other places. So in short THREE thumbs up. Thank you BRS for carrying these at affordable prices.

I bought this drill bit in order to drill my tank for an overflow. I have since drilled two more tanks with this same bit and it continues to cut great! Do not be afraid to drill your tank, with the low cost and quality of these bits you cant go wrong!

I had some oscillation with my larger bits( shaft was not perfectly concentric). It still worked fine, just had to cut slower.

Ordered a 35mm and a 45mm to drill overflows and returns in my tank. Made quick work of the 1/2" glass on my aquarium with very minimal chipping (almost unavoidable in thicker glass). Would recommend for anyone needing to drill a tank.

Bought the 1" bulkhead. BRS support said I needed the 45mm drill bit. They were right. Was a breeze to drill my 75g, especially since a local glass shop was going to charge me $20/hole. Well worth the money and time.

I ordered a 45mm bit to drill 5 holes in the back of my 120 gallon for the 1" ABS Bulkheads. The glass was 1/2 inch thick. I was worried this bit would burn up or wear out before I was able to finish all the holes. However, I completed all 5 holes in about 2 hours (First time grinding glass and I was very cautious, maybe to cautious) and kept a steady stream of cold water on the bit. It worked like a charm and the bit is still in brand new condition ready to make more cuts!!! Definitely give this bit a try. Great Value!!!

I drill two holes for 3/4" bulk head when making a custom sump. I was skeptical about it beacuse of the price, but they worked out great and didnt even break the thin glass of 10g aquarium. Then used it on making a 60g cube reef ready. Great item and a great price

Drill bits worked as advertised, cut through 1/4" glass easily. Used a cheap cordless drill with clutch. Didn't need drill guide just held bit at angle to establish a groove.

Used this for my custom sump for my new tank. I have to say that it worked great. Worth every penny.

I was a little nervous at first, with this being my first time drilling glass although it turned out to be a breeze. I purchased the 65mm bit for sch80 1 1/2" bulkheads and drilled 3 holes no problem. It seems like it would be hard to "mess up" unless you are carless. Easy and slow is the way to go.

I have began to convert all of my old non-drilled glass tanks with these drill bits and they work phenomenally. I have drilled 11 holes and the bit is still as good as new. The last three were half inch glass and this drill cut through them in no time, maybe 3 minutes each. Fantastic tool and a must have if you want to utilize a sump system. Forget buying an external overflow siphon, for a fraction of the price you can create a fail-safe drilled tank that looks awesome!

I used the 45mm on a 20 gallon tank. Super easy, and drilled through in about 3 minutes.

Simple and easy to use while following instruction on BRS TV, also you know you're getting the right size if you match the size that the bulk head states it needs on it's product page.

I purchased this to drill four holes in three 40gal breeder tanks that I'm using for my custom refugium under my 320 setup. After I was done with the four holes the bit looks like its still has plenty more to go, and for the price should I ever need to drill again, this is the only place I will purchase from PERIOD!!!

I drilled my cornerflo tank for a extra bulk head to run another overflow and quite things down. I was nervous about drilling but after watching the how to videos it went really easy. I would recommend a guide for multiple holes or where your concerned with spacing as the 45 deg angle technique worked but could be challenging with limited space.

Just got my 48mm bit today and started practicing. I am definitely getting the drill guide before i go crazy on my display tank. But this thing works great. The price is great too

Great product a little hard to control at first but the more you use it the easier it is. I recomend the drill guide if it's your first time to drill glass it will help you drill it right where you need it not where it wants to go.

I was a little nervous about the quality of these since they are so cheap but it worked great. Granted I've only cut one hole so far, so I'm not sure how long they last, but I got a clean hole and couldn't have asked for more.
