Can I Use My Hammer Drill to Install Tapcons in Concrete?

Your hammer drill should work just fine for one that size! I've installed plenty of Tapcons with mine, even used it for 1/2" screws. Just a tip: don’t overtighten them, or you risk breaking the heads off. It really helps to clear the dust out of the holes before you screw them in. I learned that the hard way; breaking heads about 20% of the time really adds up! Always wear a mask and some eye protection too, that dust can be nasty!

For such small bits, you probably don't even need the hammer mode. I usually just hand-tighten my Tapcons to avoid stripping or snapping them. It’s a good way to keep things simple or if you're just starting out!

I think your hammer drill will work, just be careful not to break the heads when you screw them in. Once I figured out to blow out the dust from the holes, I had way fewer issues! By the way, if you do break any heads, I've found a pair of pliers really helps get out those stuck pieces.
