it's a brand new 18v DeWalt DCD950KX hammer drill, $300.
If it's brand new, and putting a normal twist drill into it shows that you're not hitting metal, maybe you can take it back to the store for a refund. That's what I'd do.

Calling a tool that can't drill a 5/32 inch hole more than 1/4 inch deep into concrete a "hammer drill" isn't just misleading advertising, it's fraud.

You might just have a defective product, too. Any hammer drill, even a cordless one, should be able to do what you're wanting to do.

it did it. 5 tries later. it wasn't the drill or the bits. must be a lot of rock in the slab. in clean concrete it did fine, even with the bits i thought were shot.

thanks for the input. now on to the drywall...

Having drilled my fair share of holes into concrete, it had to be something other than concrete that you were hitting.
I've even had success drilling into concrete with a masonry bit and a plain cordless drill.
If you hit metal, the tip of a masonry bit will turn into a blob of metal. It will look as if it melted (technically it did).
Glad you finally got through.

that's the funny thing, the bits are fine, they just stopped.
