  1. 1

    Place the porcelain plate onto a horizontal surface. Attach a diamond hole saw onto the electric drill. Plug the drill into power source.

  2. 2

    Decide where you want the hole to be in the porcelain plate. Mark it with a with a piece of duct tape. Duct taping the spot where you want to drill a hole preserves the porcelain so it will not crack when you start to drill.

  3. 3

    Position the anti-slip guard plate onto the spot that you have applied the duct tape to. Press down hard on the anti-slip guard plate for it to stick to the location. The more pressure you apply the firmer it will attach to the porcelain.

  4. 4

    Push the diamond hole saw into the size hole on the anti-slip guard that you want to drill into the porcelain. Slowly start to drill for five to 10 seconds at a time. Stop and allow the drill to cool between each drilling interval. Drill until a slight depression is made.

  5. 5

    Remove the anti-slip guard from the porcelain. The porcelain has a depression from the preliminary drilling. The anti-slip guard is no longer needed to continue drilling the hole into the porcelain plate.

  6. 6

    Replace the diamond hole saw back into the round depression on the porcelain plate. Resume drilling again in intervals of five to 10 seconds.

  7. 7

    Take a wet sponge and cool the drill bit in between the drilling sequences to preserve the drill bit and to prevent overheating. Repeat Steps 5 and 6 until the hole is completely drilled through the porcelain plate.

Tips and warnings

  • Always wear safety goggles when operating any drilling machinery.
