Drill the bottle without causing breaks, cracks and splinters

For a few drilling jobs, greater sensitivity is required than when drilling bottles. The round bodies have a basic tension that has to be outwitted. In addition, glass is one of the hardest materials that can only be penetrated with even harder materials. Because of their round shape, bottles are also unwieldy.

Dosage is the key factor

Technically, drilling glass with attention and patience is a solvable medium-difficult task. The right drills and a slow, controlled approach are essential. The drilling process is more like a removal than a piercing. A kind of temperature management helps to protect the bottle glass from overheating.

The temperature control can be controlled by the time factor and external cooling. Turning the drill slowly, pausing sufficiently often and using cold water keep the heating within harmless limits. If in doubt, the drilling process should be interrupted longer. Otherwise, cold water on hot glass can cause a voltage discharge instead of the cooling effect.

How to drill a hole in a bottle

  • Glass-compatible drills with carbide or diamond tips (1.0 mm and 0.5 steps)
  • Masking tape
  • Storage vessel or
  • Rubber mat and retaining wedges
  • Cold water
  • Drill (€ 48.00 at Amazon *) with adjustable speed if possible
  • Spray bottle (€ 12.99 at Amazon *)
  • safety goggles
  • working gloves
  • Respiratory protection

1. Clothing and protective equipment

When drilling, do not wear outerwear with wide sleeves and dangling jewelry. Only drill with eye and breathing protection and work gloves. When drilling glass, microfine glass splinters are created that are blown up by the draft.

2. Attach slip protection

Apply masking tape in two to three layers over the drilling site, which will hold the drill bit in place.

3. Store the bottle

Place the bottle in an elongated vessel and, if necessary, stuff plastic bags or fabrics on the side between the inner wall of the vessel and the bottle body. Alternatively, you can lay out a non-slip mat and fix the horizontally placed bottle with two side wedges.

4th. Initial drilling

Clamp a carbide or diamond drill bit between 0.9 and 1.2 millimeters in size in the drill. Work with the lowest possible turning speed.

5. Cool

Spray cold water around the borehole.

6th. Boring out

Drill the hole in 0.5 millimeter steps until the target diameter is reached.

Tips & Tricks If you spray hair or icing spray, as it is known from sport, on the drilling site, you reduce the dangerous flight of fine fragments.
