Just bought one of these. Or rather one of our Clients is paying for the gear![wink ;) ;)](/forum/styles/smilies/icon_wink.gif)
We need to diamond drill a load of post holes into reinforced concrete, 42.4 CHS posts, so 80mm ish dia holes, then grouted in and finished off with a laser-cut disc.
Any recommendations on decent quality core bits. Need 400mm long. 1 1/4 UNC thread. Nimbus? Golz? There were turquoisey-coloured barrels i used years ago, anyone have a stab at the make?
