Any craft or project that requires drilling a hole through glass is easy. It is just a matter of using the correct drill bit to make it a success. Always use a drill bit specifically for glass.

What you need:

  • Masking tape, packaging tape, or painter’s tape
  • Marker
  • Gloves
  • Safety glasses or dust mask
  • Glass drill bit
  • Oil or any applicable lubricant
  • Cordless or corded drill

Steps on how to drill a hole in a glass (door, panel, or glass with a flat surface)

  • Determine first what time of glass you will be drilling a hole to. Research on the recommended speed for glass materials.

  • Put a reference mark on the glass where you want to drill the hole. The mark will serve as your guide as you begin drilling the hole.
  • Then tape the outside of the glass right where you want to drill the hole and on the part where you will be holding the glass while drilling the hole. This trick will prevent the drill from slipping once you start drilling.

  • Start at a very slow RPM (Revolution Per Minute) just enough so you can create a small dent or mark on the glass. Then, remove the tape and continue drilling at 400 RPM. But before drilling fast, if necessary, use a larger bit to enlarge the initial hole you created on the glass. While doing this, make sure that the glass is firmly supported. Also, do not put too much pressure on the drill or press too hard to avoid breaking the glass.

  • Or if you are drilling a hole on a horizontal surface, you can put a little oil around the area to prevent overheating.
  • Slow down the speed and lighten up the pressure when you are close to breaking through as this is the phase where the glass is most fragile. Another way of drilling a hole with a sure way of not chipping or breaking the glass is to just drill a hole halfway through. Then, carefully drill another hole on the other side until you meet the first hole on the other side in the middle.

How to drill a hole in a glass bottle

If you are considering doing Do-It-Yourself projects, you might want to turn your empty wine bottles into something useful and beautiful.

  • A drill press is easier to use compared to a handheld drill. But if drill press is unavailable, cordless or corded grill is OK.

  • Wrap the part of the bottle where you want to drill a hole with masking tape, packaging tape, or painter’s tape.
  • Mark the tape with a dot, enough to make it visible. Again, the dot will guide you in the placement of the glass bottle hole.

  • Place the bottle on a towel or a cushioned surface. Make sure the back of the bottle is firmly supported to prevent rolling, sliding, or shifting.
  • Use a small spear-tipped carbide or diamond bit for a starter hole.
  • Wear safety goggles and gloves and use your non-dominant hand to secure the glass bottle. Make sure the hand is on a safe distance from where you will be drilling the hole. Or you can position the bottle neck and hold it between your knees so to hold it securely. Another option is to position the neck part or upper portion of the glass bottle up around 45 degrees so there is no need to move your handheld drill up and down.

  • If working on a thick glass, make it a point to halt from drilling every 5-10 seconds. Continuous drilling risks the bottle glass to break or shatter. Spray the area with some cold water using a sprayer. Another option is to wash the drilling area with running water and continue working on that hole.
  • Position the tip of the bit on the center of the maker dot. Now, for the starter hole, begin with slow speed and moderate pressure. Keep drilling until the tip of the driller bit breaks through the interior of the bottle glass.
  • Change to a larger bit if you prefer a wider hole or until the desired size is attained. Apply the same rules the same way you did with the original or starter hole; low to moderate pressure, keep the glass bottle cool and lubricated.

  • Remove the tape and file or sand the edges of the hole to smooth them out. Roll high grit sandpaper and insert it into the glass hole. Work your way through the hole until sharp edges are smoothed out.
  • Rinse the glass with to remove glass particles.
  • Dry the glass bottle and install a rubber gasket over the hole. Apply a little bit of glue to secure the rubber grommet.

Reminders on how to drill a hole in a glass so it does not break

  • Always use a new drill bit. Old drill bits tend to get dull which risks the glass to break. And use the appropriate bit for glass.
  • Firmly support the glass. Put the glass on a cushioned or even surface. Another approach is to put the glass bottle in a small tub or ice cream container enough for it to fit. Add a pile of newspapers into the tub for cushion and to avoid drilling a hole into the container.
  • Start by making a small hole. Change the size of the drill bit as you go until the final size is achieved.
  • Also, always start slow, and then gradually change the speed for better results. The recommended drill speed for glass is about 400 RPM.
  • Keep the glass cool by constantly spraying water or oil as you work. The drill friction can heat up the glass material making it prone to breaking, cracking, or shattering.
  • Follow the ¾ inch rule. Do not drill on the sides or edges of the bottle glass as these are the parts with less support. If not on the center, then drill a hole at least ¾ inch away from the sides or edges.
  • Smooth the hole after drilling. If you intend to use your drilled glass bottles as hanging decors, then file the hole to smooth jagged edges. Sharp edges pose safety risks and can potentially damage the rope, string, cable, or wire you plan to thread into the glass hole.
  • Put a rubber grommet into the hole after smoothing. You can purchase affordable rubber grommets from home improvement shops or hardware shops. These rubber grommets come in different sizes or diameters. Apart from aesthetics, rubber grommets are extra protection in place.
  • Always clean the glass with running water after drilling a hole to remove glass particles.

Drilling holes in glass panes or glass bottles look pretty easy, but one simple mistake can be a waste of time, energy, and materials.
