Greetings. I want to drill a couple of additional bolt-holes through a 100x100mm concrete spur post, which is currently supporting my fence. I've got an SDS drill, but I'm worried that the post may shatter (after previous "experience" with house-bricks, leaving a nice series of exit wounds on the other side of the wall). Has anybody tried this? Any tips? Thanks in advance, Al. (email address no longer connected)
