Save money and time.

Don’t haul your tank all the way to the store to have it drilled. Use our diamond coated glass drill bits.

Drilling glass is actually pretty easy with the correct tools. Diamond coated drill bits will allow you to drill a hole where ever you need in non-tempered glass for bulkheads, or any other plumbing your system desires.

For drill bit and bulkhead compatibility please see Full Details below.

Product Questions

Can you drill tempered glass with the diamond bits? I have heard not....
Question by: Daniel on Oct 29, 2013, 10:04 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 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!
Answer by: Connor on Feb 3, 2016, 12:09 PM
At what point is it needed to a schedule 80 bulkhead? Would this be for return to tank and or overflow too? I am planning a 125 Gal reef tank with two overflows, two returns. Thanks for any help!
Question by: tim bowser on Dec 18, 2016, 1:49 PM
Great question! The schedule 80 fittings are used for their durability and aesthetics. In most aquarium applications, we do not use high enough pressures to worry about the pressure rating between sch40 vs sch80. :-)

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 AM
The 45mm drill bit would be the ideal drill bit for a 3/4" sch80 bulkhead.
Answer by: Bulk Reef Supply on Jan 3, 2014, 9:38 AM
What size bit will I need for 1/2" SCH 80 bulk heads?
Question by: Kendall on Jul 20, 2016, 9:10 AM
Hi Kendall,
For a ½” Sch 80 bulkhead we suggest using a 35mm glass whole saw.
Answer by: Charlie on Jul 20, 2016, 12:18 PM
What size Hole Saw do I need for a 1" sch 40 BH?
Question by: Dustin on Mar 15, 2022, 9:06 PM
Hey there,
Thank you for reaching out to us. You will need a 1 3/4" hole.
Answer by: Matt Lucero (BRS Staff) on Mar 16, 2022, 8:14 AM
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 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 on Jan 28, 2016, 4:06 PM
Do these glass drill bits work for acrylic also?
Question by: Barbara on Jan 31, 2014, 4:22 PM
-4
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.
