  • Good quality By on 8/13/2017

    I have cut a total of 10 holes now and the bit still looks like new.
  • Dulls too quickly By on 8/6/2017

    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.
  • Good product. By on 5/25/2017

    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.
  • Michael would recommend this product By on 3/14/2017

    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 By on 12/30/2016

    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.

  • Amazing drill! 35 and 45mm By on 11/21/2016

    It was my first time to drill my tank, and this product was easy to work, I recommend it! greetings from México!
  • Dulls quickly By on 9/29/2016

    3/4" bit got dull before finishing the 1st hole through 1/2" glass. Second hole took almost and hour to drill
  • Drilled my first tank! By on 9/9/2016

    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.
  • Bits work great By on 9/4/2016

    Drilled two holes with the 60mm and one with the 48mm. Was super easy, had no problems.
