a rotary hammer works differently from a hammer drill. thats why the

if you were an expensive sds bit, cut the shank and place the bit into
a hammer drill, its performance would be no where near that of a rotary
hammer using a cheap $2 bit

its in the design of the drill, sds is just the tip of an iceberg.

Precisely.

Its in the hammer action, not in the fact it says 'SDS' on it.
