It might be too late for this, but in my own experience fastening to concrete I definitely prefer wedge anchors to tapcons. If you have a nice SDS I am sure that tapcons are lovely, but for my uses I either strip the hole, snap the tapcon, or it drives perfectly. 1 in 3 worked for me so until I started used wedge anchors.

I have both conventional hammer drills and SDS. It's not the drill. Tapcons stink no matter what.

I don’t disagree. What I meant though was an SDS results in a better hole for the tapcon and more successful driving. At least that’s what I have been told. As I said I don’t have an SDS

I fell for all that, too. Tried a better drill. Bought the special Tapcon bits and drivers. Cleaned the hole like we were doing surgery.... still broke 2/3 to 3/4 of the damn things...

Oh shit, well that halts my own desire to splurge on an SDS for tapcons then. Guess I’ll have to find another use to justify it hahah

They are absolutely fantastic for making holes! Also crazy good for removing tile (with a flat chisel bit). Just pick some other concrete fastener...

Titen is a better product for screws into concrete if you don't want to use wedge anchors.
