  • 45 mm Diamond Coated Glass Drill Bit By on 11/23/2016

  • 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.
  • 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!
  • Works weill..... By on 4/2/2016

    These work well and BRS always used to be my go to place for glass drill bits but they've recently raised the prices on these by more than 50%!!!! what gives?!?! once again it feels like members of this hobby are being taken advantage of.
  • Worked great for two holes By on 2/21/2016

    I was nervous drilling my first tank but after i did the first one i had no hesitation in the second one. It seems like it could do more holes, but now it is no longer necessary.
