Diamond Coated Glass Drill Bits

  • Worked Perfect! By Seth on 5/5/13

    I've never drilled glass before but after watching the BRS video and buying the bit, I can now say I have a perfectly cut hole in my sump. Thank you BRS!!
  • Good price does the job By Jeff on 5/4/13

    Drilled as it was suppose to.
  • pretty impressed By eric on 4/15/13

    1st time drilling glass and couldn't have worked smoother. Followed the BRS video and set the tank to drill horizontally and built a little dam to hold water around the bit. I went without a guide tilting the drill about 20 degrees to get it started and slowly squaring it up. Took less than a minute to go through a 1/4" wall.
  • Worth the money By Brandon on 4/9/13

    This is the first tank I have drilled and I was very worried about it but these bits are very high quality and made it very easy. After I drill the first hole now I don't worry about it anymore. Thanks BRS also for the great video's to go along with it. The Drill press stand helps a lot also. Just be careful hard to tell how hard you are really pushing on it when you get the springs compressed down a ways.
  • Easy By Matt on 4/6/13

    I couldn't believe how easy it was to drill glass. I made (4) 48mm holes in my 40 gallon breeder. They were all at the same height on the back glass of the tank. I don't think I could have kept the bit steady without making a wood jig. It took me about 20 minutes of drilling per hole.
  • awesome prices here By John on 3/28/13

    best prices i could find for these
  • Good for the price By Ronald on 3/24/13

    Little on the cheap side of bits, quality wise. Great buy for the money, and preformed as advertised drilled 8 holes before the bit started to show wear. BRS site was a little confusing in determining what size to buy for the 3/4" Schedule 80 Bulkhead Slip X Thread Dimensions, which state to use the 45mm, but the bit page stated to use the the 42mm. Glad I went with the 42 its a perfect fit. One key advice. take it slow and keep it wet and cool while drilling .
  • Easy to use By Travis on 3/15/13

    I was a little nervous at first to dill the tank but it was so easy with this tool. I got the 48mm bit and drilled two holes in less than 20 minutes.
  • Worked just like it was suppose to. By Rick on 3/15/13

    First time drilling aquarium. Watch videos from BSR and project went smoothly. With no problems drilled 3 holes in aquarium for bulk heads easily with bit, A great price also.
  • Great tool By James on 3/11/13
