The manufacturing process of a universal drill
To drill holes of any size in ceramic tiles, you can make an attachment for a drill that works on the principle of a ballerina drill and a compass. To do this, you need to cut a longitudinal cut in a strip of metal 20 cm long:
Cut off the strip.
We drill holes and connect them.
This blank is welded to a pipe ring with a diameter of 40-50 mm.The internal cross-section of the latter is selected to match the mounting diameter of the protective casing on an existing angle grinder or drill.
You need to make a centering pin from a 10 cm long pin by sharpening it.
Then it is screwed into the cut of the strip with two nuts.
To use the device, you need to install a drill chuck with a tile drill on the spindle of an angle grinder without a casing.

Then it is inserted into the attachment ring. As a result, we get a drilling device that allows you to mill a hole in a circle in a tile. To do this, you need to first mark its center in place.
The fixture is adjusted to the desired radius, like a compass, then drilling is done on the underside of the tile.
