BLUEROCK Model Z1S – 4Z1 Concrete Core Drill Anchor Stand Rig 60mm Collar fits Weka DK12 DK13 DK16 M4 M-4 DM230 DM200 CB15 DS150

This made drilling a 3 inch hole in concrete a cinch, took absolutely no effort at all. A few words about assembly…the carriage section comes assembled backwards on the rail so as to better fit in the box, so you’ll need to take it off yourself with a 3/4″ wrench and reassemble the right way…also you’ll need to figure out for yourself where the handle, and ceiling binding bolt go (it’s pretty obvious). Also know that you need to have at least a 5/8″ wedge anchor AND a hammer drill with a 5/8″ masonry bit to be able to set this up properly, and you’re good to go. And remeber you’ll most likely want to remove or hide the wedge anchor afterwards, but I won’t go into that here.
