Drill a bottle without causing breaks, cracks and splinters

With a few drilling jobs, a greater sensitivity is required than with the drilling of bottles. The round bodies have a basic tension that needs to be outwitted. In addition, glass is one of the hardest materials to penetrate only with even harder materials. Due to their round shape bottles are also unwieldy.

Dosage is the deciding factor

Crafting glass with attention and patience is a solvable medium-heavy task. Indispensable are the correct drills and a slow controlled procedure. The drilling process is more like ablation than puncture. 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. Slow turning of the drill, sufficient frequent pause and cold water keep the heating in harmless context. If in doubt, the drilling process should be interrupted longer. Cold water on hot-rolled glass may otherwise cause a voltage discharge instead of the cooling effect.

So you drill a hole in a bottle

  • Glass-compatible drills with carbide or diamond tip (1.0 mm and 0.5 steps)
  • Masking tape
  • Storage vessel or
  • Rubber mat and retaining wedges
  • Cold water
  • As far as possible with adjustable speed
  • spray bottle
  • safety goggles
  • working gloves
  • respiratory protection

1. clothing and protective equipment

Do not wear outerwear with wide sleeves and dangling jewelery when drilling. Only drill with eye and respiratory protection and work gloves. Glass drilling produces microfine glass splinters, which are already whirled up by the draft.

2. Secure the slip guard

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

3. Store the bottle

Place the bottle in an oblong container and, if necessary, laterally stuff plastic bags or substances between the inner vessel wall and the bottle body. Alternatively you can lay out a non-slip mat and fix the horizontally placed bottle with two lateral wedges.

4. Initial drilling

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

5. cooling

Spray cold water around the hole.

6. Bore out

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

Tips & Tricks

If you spray hair or icing spray, as it is known from the sport, on the drilling site, you reduce the dangerous fine splinter flight.
