Review on Efficient Milwaukee 48 20 7497 SDS Plus Tapcon Installation Tool by Frank Villanueva

Works great! It's a bit awkward turning screws with a full-size impact drill when you're trying to get the head into the 'socket' first and then hammer it in. In any case, it makes sense to screw them a few turns into the pre-drilled holes by hand and then drive them in. These are new tools to me, so maybe that's how they should be used. idk The bits themselves quickly stuck into the concrete blocks where I installed the cameras.
