How to Drill a Hole in a Glass Bottle to Make a Glass Bong


If you are looking for a creative way to enjoy your herb or tobacco, you might want to try making your own glass bong from a glass bottle. A glass bong is a device that filters and cools the smoke from burning herb or tobacco through water, making it smoother and less harsh on your lungs. You can make a glass bong from any glass bottle, such as a wine bottle, a beer bottle, or a liquor bottle, as long as you have the right tools and materials.

In this blog post, we will show you how to drill a hole in a glass bottle to make a glass bong, step by step. You will need:

  • A glass bottle of your choice
  • A power drill with a small spear-tipped carbide or diamond bit
  • A larger drill bit of the same type, depending on the size of the hole you want
  • A piece of masking tape or painter’s tape
  • A felt-tip marker
  • A folded towel or a soft pad
  • A bowl of water or a spray bottle
  • Protective goggles, dust mask, and gloves
  • A 600-grit diamond file
  • A rubber grommet that fits the hole you drilled
  • A metal or glass downstem and bowl that fits the grommet

Before you start drilling, make sure you are working in a well-ventilated area and wearing your safety gear. Also, do not attempt to drill tempered or safety glass, as it will shatter when you apply pressure.

Step 1: Mark the drill site

Choose the spot where you want to drill the hole on your glass bottle. It should be on the side of the bottle, near the bottom, and following the curve of the bottle. Avoid drilling on flat or thin areas of the glass, as they are more likely to crack or break.

Make an X with two pieces of tape over the drill site. This will help prevent the drill bit from slipping on the smooth glass surface. Then, use a marker to draw a dot at the center of the X. This will be your guide for drilling.

Step 2: Secure the glass bottle

Place the glass bottle on a folded towel or a soft pad on a stable work surface. The towel or pad will cushion the bottle and prevent it from rolling or sliding while you drill. Make sure the taped side of the bottle is facing up and accessible.

Step 3: Drill a starter hole

Fit your power drill with a small spear-tipped carbide or diamond bit. These bits are specially designed to cut through glass without damaging it. You can find them at most hardware stores in various sizes.

Align the tip of the bit with the dot you marked on the tape. Hold the drill at a right angle to the surface of the glass. Start drilling at a low speed and moderate pressure. You can start at a 45-degree angle and then gradually move to a perpendicular position as you drill.

To prevent overheating and cracking the glass, you need to keep the drill bit and the glass wet while drilling. You can either dip the bit in water before drilling, spray water on the glass while drilling, or submerge the bottle in water while drilling (make sure your drill is waterproof if you do this).

Drill slowly and carefully until you make a small hole through the glass. Do not push too hard or too fast, as this can cause the glass to shatter. Also, reduce your speed and pressure as you near the end of the hole to avoid chipping.

Step 4: Enlarge the hole

If you want to make a larger hole than your starter bit can make, you need to switch to a larger bit of the same type. Remove the tape from the bottle and fit your drill with the larger bit.

Drill through the existing hole using low speed and moderate pressure. Keep spraying water on the glass to cool it down. Enlarge the hole until it reaches your desired size.

Step 5: Smooth the edges

The hole you drilled may have some rough or sharp edges that can cut you or damage your downstem. To smooth them out, use a 600-grit diamond file to gently sand them down. You can also use water to lubricate the file and the glass.

Be careful not to file too much, as this can weaken the glass or change the shape of the hole. Just file enough to remove any burrs or chips.

Step 6: Insert the grommet

A rubber grommet is a ring-shaped piece that fits into the hole you drilled and creates a tight seal for your downstem. You can find rubber grommets at hardware stores or online in different sizes.

Choose a grommet that matches the size of your hole and your downstem. Insert the grommet into the hole and push it until it sits snugly. You may need to use some force or a tool to do this.

Step 7: Insert the downstem and bowl

A downstem is a tube that connects the bowl, where you put your herb or tobacco, to the water chamber of the bong. A bowl is a small container that attaches to the end of the downstem and holds your herb or tobacco. You can use metal or glass downstems and bowls, as long as they fit your grommet.

Choose a downstem and bowl that match your grommet and your preference. Insert the downstem into the grommet and push it until it reaches the bottom of the bottle. The downstem should be submerged in water by about an inch. Then, attach the bowl to the end of the downstem.

Step 8: Enjoy your glass bong

You have successfully drilled a hole in a glass bottle and made a glass bong. Congratulations! Now you can fill your bottle with water, pack your bowl with your herb or tobacco, and enjoy your homemade glass bong. Remember to clean your bong regularly to keep it in good condition.
