masonry drill warning

Anyone know why a 1/4 masonry drill has a warning "don't use on a drill
press"
? This came from a local hardware store.

because you're supposed to use then with a hammer drill, not a drill
press.

they work by crushing concrete or whatever, not cutting into it.

If you don't believe it, just look at the tip. There's nothing cutting or
sharp about it.

With a hammer drill you can drill masonry with regular bits, but they will
break quicker.

He may not have a rotary/percussion bit..there are common "hardware store"
masonry bits that are for rotary use only, as shown he
