Why rent a core drill and drill bit when you can make one yourself! It's not about drilling concrete. You will see several versions of Vidlák's 150 mm drill and not only that, you will see Vidlák's drilling ecosystem in action. You can write your experience with drilling larger diameter holes in the comments. Vidlák's DIY challenge. If you have some useful machine of your own design at home (stove, small tractor, PV plant, perpetual motion machine) and you want to show it off to the world, we can make a video about it together...
