I 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.

Drilled 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.

I 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.

Worked great to cut a hole in my sump for an external skimmer fast and clean and ready for more cuts. used plumbers putty to create a water pool to help cool the bit and painters tape on the other side to catch the glass plug.

I drilled my 40 breeder frag tank with this bit and it worked flawlessly! I couldn't be more happy with the end result. I was very nervous as this was my first time drilling glass but I went nice and slow and used the drill guide which in my opinion is a must.
