Recommendations on appropriate drill for drilling into concrete floor
I have a Ryobi 18.8V cordless drill and am having a very hard time drilling into concrete using a Tapconn drill bit. I literally have to put all my weight behind the drill and that is bothering my shoulders big time.
Any recommendations on what is the best way to drill holes into concrete? I am attaching bottom plates to the concrete for the purposes of framing my basement.

Is this a hammer drill?

I believe it is - it has a rotary dial on it graduated from 0 to 24. At the 24 setting it feels like it's vibrating more, so I'm guessing it's a hammer drill.

That's just a clutch of some sort on the drill for use when driving screws and is not a real hammer drill. You'll need a real hammer drill.

You could probably pick up a cheap hammer drill at Harbor Freight for around $40. It should be good enough to get you through the basement build.

You may want to rent a hammer drill from a rental store, pretty cheap, and you can get a heavy duty one.

I personally use powder-driven fasteners for interior bottom plates that aren't part of a structural hold-down transfer path. You can pick up a hammer-blow nail gun for around $20 and shoot hardened nails with washers into your plates with less effort than drilling holes, cleaning them out, and fastening with screws. Some construction adhesive and nails will hold your walls fine. A hammer drill is okay, but a "rotary hammer" is best if you're going to rent something to drill a bunch of holes in cured concrete. H.D. tool rental carries them in a range of sizes and you can rent it for as little as 4-hours.
