The bigger the object, the longer kakashi needs to transport it. He transported a nail in an instant, yet with the gedo's head or even deidara's arm he needed quite a bit of time to warp it.

Given that he needs to maintain perfect focus for extended periods of time, it's simply not practical to warp someone's limbs or head in combat situations.
