Rent one at home depot cheaply. I would not buy one for your purpose. They make a mess, so keep that in mind. Glasses are a good idea too.

A real hammer drill uses bits specific for them. Hilti and Bosch are reputable brands that are available for rent.

I own a bosch bulldog that is great for light duty drilling. I just finished pinning my framed walls to the slab with it and hex head 5/32 tapcons. Worked great.
