Product Questions

Can you drill tempered glass with the diamond bits? I have heard not....
Question by: Daniel on Oct 29, 2013 10:04:00 AM
Hi Daniel,
No you cannot drill tempered glass. If your glass is tempered there isn't really any modifications that can be done to it as it will shatter. Fortunately most aquariums do not use tempered glass (though its more common on the bottom panel).

I would like to get a couple of drill bits for a 1" bulk head and a 3/4" bulkhead, problem is I don't know what type of bulkheads they are, SCH OR ABH.
Question by: Carlos on Jan 25, 2016 10:35:00 AM
Great question!
ABS is always a black plastic color. Schedule 80 will be gray. In most cases the bulk heads in the hobby are ABS. Feel free to let us know if you have any further questions!

I have a 45mm will it work on a 3/4 sch 80 bulkhead or will it be to big?
Question by: Ryan on Jan 3, 2014 9:38:00 AM
The 45mm drill bit would be the ideal drill bit for a 3/4" sch80 bulkhead.

How many holes can 35mm and 45mm bit cut before it isn't an idea cutter ?
Question by: Louis V. on Jan 23, 2016 8:15:00 AM
Great question!
You could get around 6 cuts per drill bit before the bit tends to slow down. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 28, 2016 4:06:00 PM
Do these glass drill bits work for acrylic also?
Question by: Barbara on Jan 31, 2014 4:22:00 PM
Hey Barbara,
For acrylic you just need a plain toothed hole saw bit like the set linked below, no need for a diamond coated drill bit.

  • Works beautifully when used with care By Jack 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 Brent H on 12/9/2015

    Used the same bit on 5 holes and it's still sharp
  • Works as advertised By Matt 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 Eddierg on 10/22/2015

    Easy to use and cuts like it should
  • Got the job done By Bryan D 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.
  • Great quality By Shelley on 10/1/2015

    Product worked great!
  • High Quality Bit By Bill on 9/19/2015

    Bit worked great and could probably drill dozens of holes
  • It is what it is By Lukas on 8/30/2015

    Cut four holes and still has enough left to do more.
  • Perfect By Dominic on 7/25/2015

    Cut the glass great, no complaints!
  • Good hole saw By Jul on 4/16/2015

    Drilled six holes and still going strong
  • Cheaper than paying someone to drill! By Kendall on 4/9/2015

    I have other drill sizes but not the one I needed this time for just one hole. I looked all over for a source that would drill my tank for a reasonable price. I decided to buy the size bit I needed and do it myself. Works great and is easy to use.
  • well built By cj on 3/29/2015

    I had no complaints. It's a well built tool cuts through glass like butter!!!!!
