Drill a drain hole in concrete retaining wall

I have a concrete retaining wall 120 mm thick. When it rains water collects at a certain point in front of the wall. I'd like to have a 50mm diameter hole drilled at a 30 degree angle down from horizontal in the wall to drain the water. I would estimate total drilling thickness including the angle 130-160 mm. Someone with the right drill and drill bit should be able to get this done in a few minutes.
