Hi, I need to drill a 32mm hole, horizontally, through a 230mm x 350mm brick pier (through the 350mm deep part). This is to connect a rainwater downpipe diverter on one side, to the water butt on the other side. (going round the pier would look untidy and foul the gate)
I can see there are all types of drill bits available but considering this will be a one-off need, what is the cheapest type of drill bit that would be long enough to go through 350mm of brick and mortar using a standard Bosch electric hammer drill? Or, I guess with a shorter bit, I could drill from both sides and hope they meet in the middle :-)
Thanks in advance
