How Do You Drill a Hole Easily in a Glass Aquarium?

People use their imagination when they wish to make something exceptional for their fish aquarium by making a bulkhead and cutting a hole near the top of an ultra-transparent glass aquarium (i.e., waterproof plastic fitting that prevents the hole from leaking).

Everyone has a different method for drilling glass tanks, including using a drill press, mineral oil, dish soap, and various other possibilities. This article describes the tried-and-true method we ultimately settled on. Including the following:

Step by Step, Drill the Aquarium

  1. Place the aquarium on its side so the tank wall will drill upwards to begin the procedure. Place the wood piece, so it is flush with the tank's rim and side edge. Place the hole saw in the desired location for the bulkhead and mark the center of the hole with a dot. Mark the wood so you know which side touches the rim.

  2. Remove the wood from the tank, mark the spot with a dot, and drill a hole there. The wood is a guide to keeping the hole saw from moving while drilling.

  3. After creating the guide, align the wood piece with the tank's rim and side edge and clamp it in place. To prevent the glass hole from falling out and breaking your tank when drilled, tape the aquarium's interior where you can see the hole. The tape also lessens chipping, resulting in a relatively clean hole.

  4. You should pour water into the guide's hole. To keep the glass moist, you'll need to refill it because some water will leak out constantly. Water aids in cleaning up the dust and prevents the hole saw from becoming too hot, as suggested by the experience of Aquarium supplies in Bellingham.

  5. Pull the electric drill's trigger to start it spinning slowly, then gradually speed it up to a moderate pace. Let the weight of the drill carry the hole saw downward while applying light, uniform pressure. Additionally, strive to keep the spot saw level and prevent drill tilting to avoid uneven hole cutting. The drilling process could take 5 to 20 minutes, depending on the thickness of the tank, to steadily file your way through the glass.

  6. Pour extra water onto the hole saw and into the guide's hole if the glass begins to squeak. Then, keep drilling.
  1. If the frequency of the grinding sound begins to fluctuate, the glass hole has either already broken through or is soon to. Although the hole may have slightly sharp edges, the bulkhead's gasket will cover them, negating the need to deburr the hole. Pull the tape off cautiously, careful not to touch the glass hole's interior.

  1. Place the aquarium in its final location before building the bulkhead because the hole is relatively weak. The locking nut should be on the tank's exterior, and the flanged head should be inside the tank as you insert the bulkhead through the hole. With pliers, tighten the locking nut down after tightening it with your fingers.
