Worked great By Adam on 8/31/2018Adam would recommend this product to a friendDrilled 2 holes for 3/4” bulkheads and it worked prefect on both made it easy. Nice clean holes recommend using a guide to start holes I drilled outside and just put the hose on and let it run to keep the bit cool while drilling. Would order again if needed

Perfect for the job By Kyle on 8/13/2018Kyle would recommend this product to a friendHad to drill 4 holes in the back of my 125. First time ever drilling and first tank that big....ballzy I know.... that drill cut perfectly with virtually no chipping. Great product
works great By tc on 4/26/2018tc would recommend this product to a frienddrilled two 65mm holes and worked as advertised. Takes a while so don't hurry. You'll be happy in the end.

decent price, quick to dull By tyler on 2/27/2018tyler wouldn't recommend this product to a friendI got the 60mm bit, figuring id give it a shot, considering its half the price of the ones i normally get. I don't know if the one I got was used or just defective, but the first hole took north of 2 hours, and the second after 3+ hours i gave up and ordered the ones i normally do. I have drilled alot of glass in my time and know what im doing, this bit just didnt seem to stand up to 8mm glass, I was hoping it would be great as BRS products always over deliver, but unfortunately this did not.
Solid performance By Stark on 2/2/2018Stark would recommend this product to a friendUsed this for 2 tank builds, total of 5 holes - would probably be able to drill a few more safely. Use the bit the right way (keep it lubed, keep rpm bursts to a minimum) and it is well worth the cost. Thanks BRS
Worked Great By GT on 10/11/2017GT would recommend this product to a friendUsed to drill two holes with no issues.
Good quality By Joseph on 8/13/2017Joseph would recommend this product to a friendI have cut a total of 10 holes now and the bit still looks like new.
Dulls too quickly By Ryan on 8/6/2017Ryan would recommend this product to a friendI was unable to complete my second 65mm hole in my 1/2" thick Oceanic glass aquarium before the bit lost its sharpness. Am purchasing another to finish the job and drill a third hole.
Good product. By Shawn O on 5/25/2017Shawn O would recommend this product to a friendDrilled 3 holes for the 1" bulkheads and they came out pretty good. One chip where I rushed the first hole. The other 2 holes looked like a pro did them.
Michael would recommend this product By Michael on 3/14/2017Michael would recommend this product to a friendI bought the 65mm to install a shadow overflow on a 150 gal. I was almost certain the side glass was not tempered but I was still prepared to clean up a shattered mess. Good news, two holes drilled successfully! Go slow and let the bit do the work. Watch lots of videos too.

Can you drill tempered glass with the diamond bits? I have heard not....
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).
I would like to get a couple of drill bits for a 1" bulk head and a 3/4" bulkhead, problem is I don't know what type of bulkheads they are, SCH OR ABH.
ABS is always a black plastic color. Schedule 80 will be gray. In most cases the bulk heads in the hobby are ABS. Feel free to let us know if you have any further questions!
At what point is it needed to a schedule 80 bulkhead? Would this be for return to tank and or overflow too? I am planning a 125 Gal reef tank with two overflows, two returns. Thanks for any help!
I have a 45mm will it work on a 3/4 sch 80 bulkhead or will it be to big?
What size bit will I need for 1/2" SCH 80 bulk heads?
For a ½” Sch 80 bulkhead we suggest using a 35mm glass whole saw.
How many holes can 35mm and 45mm bit cut before it isn't an idea cutter ?
You could get around 6 cuts per drill bit before the bit tends to slow down. Feel free to let us know if you have any further questions!
Do these glass drill bits work for acrylic also?
For acrylic you just need a plain toothed hole saw bit like the set linked below, no need for a diamond coated drill bit.
