Anyone who has encountered the need to drill tile knows that it is not a simple matter and the main difficulty is the slippage of the drill bit on the smooth surface. As a result, we get a deep scratch on the front surface of the tile and it can already be thrown away. To avoid this, it is recommended to use a guide. It is fixed on the tile with a suction cup and does not allow the crown to "walk", and the bearings facilitate rotation. The guide is suitable for crowns with diameters from 18 to 80 mm.
