Drilling sound safely and without break

Sound can easily be burned when burned. Since the hard material such as ceramic is susceptible to breakage, impact drilling is excluded. The risk of breakage or breakage can be reduced by very slow revolutions of the hard drill. An expensive diamond drill is not essential, but it must be sharp.

Drill slowly and extend if necessary

Clay vessels and sculptures can be drilled. The brittle material, however, tends to crack when working too fast and with too much pressure. When the clay is glazed, the time required increases. Clay must be fired at least raw to be drilled.

Important for working on burnt clay is the sharpness of the tool. Frequently used and thus "blunted" drill spirals can damage the clay even at the lowest possible rotational speed. For safety's sake, new drills should be used.

Similar to all breakable materials, the risk of destruction increases with the diameter of the drill. If you want to create holes with cross-sections of more than one centimeter, pre-drilling and then expanding is the safest way. The larger the diameter or cross section of the hole that is to be drilled directly, the more the process resembles a scraping in a circular shape.

How to drill clay

    • Sharp diamond, stone or universal drills or
    • Milling drill bit for tiles
    • Drilling machine with possibly slow drilling speed
    • Non-slip surface
    • Possibly screw clamp
    • Masking tape
    • Cloths

1. Fasten the drilling object

Secure your cuttings in a stable position. A cylindrical vessel, such as a flower pot or cup, into which you drill into the ground, you can easily put upside down on a non-slip surface. If you drill on the side and on rounded surfaces, you must fix the object well. Possible is a textile "tangle of cloth", in which you embed the vessel or the sculpture. With a screw clamp you can fix position. For this purpose, they also put cloth balls in the interior of the horizontally placed drilling object and carefully screw on the clamp.

2. Non-slip drill hole

With masking tape over the drilling point, you can achieve optimal slip protection when attaching the drill bit. Bo 3. Drilling

Drill with very light pressure and the slowest possible number of revolutions. Stay patient and just make sure that clay dust develops.

Tips & TricksThe recommended moistening of the clay in many places before drilling does not help during the drilling process, but it dampens the dust development.
