Drilling pebbles - this is how it works

If holes are to be drilled in pebbles - for example, to thread them on a chain - this requires the right tool. The procedure must also be adapted to the material. How it works best is described in this guide.

What is important

  • suitable drill and suitable drills
  • break safety
  • fixation

suitable drill and suitable drills

Pebbles are subject to a high risk of breakage when drilling with a strong blow. A hammer drill is therefore not recommended. In general, you can get along well with pebbles using a normal hammer drill. Even pure rotary drilling leads to success, but takes longer.

As drills, diamond drills are best suited for all devices.

break safety

Pebbles break very easily. They must therefore be protected during drilling accordingly. At the same time, it also prevents the drill from slipping sideways on the smooth surface without marking on the smooth surface.

But since pebble is an inhomogeneous rock, the risk of breakage can not always be completely ruled out.


When drilling, the stone must be fixed firmly and immovably. This is best suited for a vise. The stone can also be protected again at the affected areas with Leukoplast against scratches from the stone cheeks.

Piercing pebbles - this is how it works

  • pebble
  • water
  • Leukoplast
  • Impact drill or cordless drill
  • Diamond drill in the required size

1. Prepare pebbles

Carefully clean and dry the pebbles. Mark the drill site with a piece of Leukoplast.

2. Breakage protection

Wrap a strip of Leukoplast around the stone and press firmly. Attach Leukoplast to the vices at the clamping points to protect it from scratches. Fix stone firmly enough. (Not too tight, otherwise there is a risk of breakage)

3. Drilling

It is recommended to drill without any impact with the diamond drill at around 750 revolutions per minute. If this is not enough, you can switch on blow. During operation, always cool the drill with water. Drilling oil can also be used.

Tips & Tricks

Even diamond-crowned cutters or diamond drills for the Dremel are a way to cut clean holes in the pebbles. The only problem is the eruption sites - where the pebble may possibly splinter. Whenever possible, you should drill from both sides to avoid splintering.
