I've got a line of old concrete posts bordering my house, I'd like to put up a wooden fence, but unfortunately they are spaced wrongly and intermittently for panels, so the best thing would be a featheredge lapped fence. Trouble is, I cannot drill into these posts to screw in the cross battens. Invariably I get in half inch or so, hit a stone, then the drill rapdily goes blunt, and goes no further. I havent tried a diamond drill bit yet, but am not too keen to splash out on one if that is going to wear out after 2 or 3 holes. Any thoughts on what I need? SDS drill with diamond bit? Give up and dig out all the old posts? Thanks for any pointers. Alan.
