Drilling porcelain - is that possible?

To attach porcelain plates to the wall, or to drill a hole in a porcelain cup, you need sophisticated technology and the right tools. But there is always the risk of leaps or destruction. How it still works best, can be found in the following instructions.

That can be helpful

  • the right tool
  • overposting
  • Understand drilling site and wet with kerosene

The right tool

There is no one hundred percent suitable tool for piercing porcelain. There are only better and worse alternatives.

Drill with a small drill and slow speeds is a good option. Start drilling with the smallest drill bit. Drill slowly and without pressure. Thereafter, the Bohrgröße can be further increased. The larger the drill, the further the speed should be lowered.

In the trade there are special drills for ceramics. In most cases, they also work very well with porcelain.

An even better option is offered by Dremel and similar multi-sanders. Then not with a drill attachment, but with the diamond grinder. This can be worked completely without pressure. Diamond hollow drills can also be used.

In any case, a suitable drill stand is recommended for a multi-sander. Thus, the risk of breakage is the lowest.

Risk: tensions in the porcelain

Porcelain may contain internal stresses that are not visible from the outside. The risk that these stresses can cause a workpiece to break apart is always given and can not be ruled out completely. However, it can be minimized by choosing the right tools.

overposting

If the drill site is crosswise taped over with tape, this serves two purposes:

The drill can not slip, causing the workpiece to shatter. But he must be placed exactly on the middle of the crossed Tesabänder.

At the same time, the Tesakreuz also helps to precisely target the drill site and actually drill it there without the drill setting the hole in the wrong place by sliding it off.

Relining and with petroleum nets

It can be helpful to relieve the back of the porcelain item with corks or similar material. The large netting with petroleum on both sides helps to ensure a more uniform heat distribution and thus avoid stress cracks.

Drill holes in porcelain - the manual

  • Workpiece made of porcelain
  • petroleum
  • Corks (pieces)
  • Scotch tape
  • Drilling machine and suitable drills, possibly ceramic drills
  • alternatively: multi-sander and diamond grinder or diamond bur

1. Fix and prepare the porcelain item

Firmly fix the object to be pierced and vigorously wet with paraffin from both sides. This must be repeated several times during drilling. Adhesive tape crosswise

2. Pre-drilling

Start with the smallest possible drill and slowly increase the drill size. After a few drill holes, re-wet with kerosene.

3. Final drilling

Drill the hole to the required size with the drill.

Tips & Tricks

In order to test the appropriate technique, similar pieces or comparable materials can be tested for waste or scrap for the best technique.
