  • 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.

  • 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.
  • Definitely Worth It By on 8/1/2016

    My buddy and I have been reefing together for about 2 years now. We've cut simple tanks, 1/4" glass, but recently, I got a 220 custom tank I needed to drill the bottom for my returns and overflows. Whoever built this thing went nuts and used true 3/4" glass all around, but also inserted a true 1/2" piece of glass on the bottom, including a 1/4" polycarbonate sheet. We got the 48mm bit and went to town. Cut 5 holes through all of it and did an amazing job in the process. Probably used this thing way past its life, but it didn't seem to care.

    If you need to cut some glass, use these bits.
  • Worked great. Reasonable price By on 5/2/2016

    Worked great. Reasonable price
  • Product does what it's designed to do By on 4/29/2016

    For some reason mine cut a square. Just kidding y'all! I've purchased 3 of these hole saw bits from BRS. They work great and are perfectly priced!
