  • 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.
  • Works beautifully when used with care By on 12/12/2015

    I've only tested my 60mm bit on a scrap plate of 1/4 glass on my drill press(@500rpm), using food grade machinery lubricant. With this arrangement I was able to cut several immaculate holes with a minimum effort.

    It's worth noting that the coated tip of the bit has a tendency to work itself dry of my oil based lubricant once a deep groove has been cut into the glass. I found that the bit cut far smoother if I lifted it from the groove every 5-10 seconds momentarily and allowed oil to seep back in.
  • Nice tool By on 12/9/2015

    Used the same bit on 5 holes and it's still sharp
  • Works as advertised By on 11/20/2015

    Bought the 60mm to drill the holes for my Synergy overflow and the bit preformed perfectly. Should be able to drill many more holes with it if need be.
  • Great product By on 10/22/2015

    Easy to use and cuts like it should
  • Got the job done By on 10/13/2015

    I am the least handy of people when it comes to figuring out how to do things, but drilling a tank was actually quite easy if you follow the BRS steps and get the right drill bit. I couldn't find this ANYWHERE locally as I needed the 60mm bit. Worked great! Clean holes. Couldnt have been easier.
