Best diamond coated hole saw drill bits come with no center pilot drills. Pilot drill bits are for softer materials such as wood or plastic.

Drilling Fish Tanks – Aquariums

Drilling in aquariums is not difficult – it is basically the same as drilling normal glass.  However, additional precaution should be taken when drilling aquariums compared to normal glass.

As they always say, measure twice and drill once.

The sizing for pipes – bulk heads and the diamond coated drill bits are different.  Be sure you have the right sized drill bit.

For example, if you are drilling for a 3/4″ bulk head, you need to be using a 1 1/2″ diamond drill bit. You can always choose to buy a set, and save.

Pipe is measured as an inside diameter.  So 1-1/2″ pipe or a 1-1/2″ fitting will have an ‘inside diameter’ of 1-1/2″.  However, the outside diameter can vary depending upon the type of pipe or fitting used and depending upon the specific manufacturer.  Be sure to measure the outside diameter properly so that you drill the correct size hole.  This may sound rather basic, but we assure you that it is a common mistake.

There is always a small risk of causing a break when drilling any glass.  While the risk is extremely small if proper drilling techniques are used, this small risk is always there.  If a break would occur when drilling in regular glass, it is frustrating, but not a major loss.  However, the loss of an aquarium is much more significant, so reasonable care should be taken.

Avoid drilling in the bottom of the tank:  The bottom of a tank is often tempered glass, but it is extremely rare for the sides to be tempered.  Additionally, the water weight on the bottom is significantly higher than on the sides of a tank.  Anytime glass is cut or drilled, micro fractures always occur along the cut, and the hole reduces the structural strength of the glass.  While tanks are generally “over engineered” to be much stronger than actually needed for their capacity, the bottom is the “weakest link” and should generally be avoided.

Drill at least 1″ from the sides of the glass:  All glass contains minor imperfections and flaws.  Micro fractures also occur along the edge of glass when it is cut.  To avoid placing any additional stress on those weak spots, we recommend staying at least 1″ away from any glass edge.

Drilling Glass Blocks

Drilling in glass block or bottles is not different than drilling in traditional glass.  If you employ the acceptable speed, use low drill pressure and lots of water for lubrication, you will not have any issues.  Glass breakage with inorganic compound bits is fairly common, however with the right diamond drill bit, it’s very rare.  There are a couple of vital facts and tips which are useful for drilling glass blocks.

There are various differing types and designs of glass block created by many alternative makers.  Most have some style of style or pattern, however, for drilling functions, there are 2 main characteristics.  Glass blocks will vary considerably on the thickness of the glass wall and a few glass block is tempered.  This info is never disclosed on the block itself, however ought to be thought-about once shopping for glass block for crafting functions.

If the glass block is 3/8″ thick, it’ll take thrice as long to drill compared to a 1/8″ thick block.

Tempered glass ought to be avoided.


Making a mini dam around the hole is the most effective cooling method for drilling in glass blocks.

Glass block contains a vacuum within. a number of the water and glass dirt can forever be sucked within once the opening breaks through.  However, it’s simple to rinse out {the within|the within} of the block with water as long because the dirty water inside isn’t allowed to dry out.  The plug from the opening can generally be force into the block – it’ll typically drop out simply once the within is rinsed.  However, if an excessive amount of pressure was placed on the drill because the hole breaks through, it will cause the plug to possess a aptitude from the break on the rear of the opening.  Normally, you’ll be able to take away the plug with a combine of needle nose pliers, however the simplest answer is to scale back the drill pressure once nearing the rear of the glass to avoid break because the drill breaks through.

Ceramic – Porcelain Tile Installation

This is probably one of the most popular use of diamond hole saws.  If you have ever been involved in any kind of bathroom – kitchen renovation, this will sound very familiar.  Regular drill bits do not work on tiles. So, you need diamond coated bits. The smaller sizes such as 1/4″ are used for screw holes. The holes that you use for installing grab bars, towel holders, soap dispensers, etc.  The mid sized hole saws such as 1 3/8″ are used for pipe holes or faucet outlets. 

Without these diamond hole saws, contractors used to break tiles and try to make grooves for pipes and faucets.
You can achieve very handsomely clean holes without the mess and hassle of wasted tiles.

What is the Recommended Drilling Speed?

Please see our post on this topic.

This is an example of a small water pool around the hole. You can use play dough or plumber’s putty  to keep water around the diamond hole saw.

The picture above was posted by one of our customers, and this was his first time ever drilling tiles.


There are also some shower heads that need much larger diamond hole saws.  There is a great 5 star review on Amazon. He purchased this large size 4 1/2″ hole saw for rain shower installation.
