Drill fence pillars
When constructing a fence with modular concrete elements, it is sometimes necessary to make openings for the passage of the hinges of the gate, for a mailbox or for the son of the bell. These elements are not originally designed to be drilled, the difficulty is to manage to drill without breaking them.
To do this, simply draw the orifice of the opening on the surface of the block. Then, using a long drill of a thin concrete drill (5 mm), drill the contour of the future hole regularly. All you have to do is finish the job with a hammer and a chisel. For even more security for the element, push it into sand.
With this tip, you can work quietly without risk of damaging your blocks.Suggest a tip for this theme
