Why should you rotate the star drill after each blow of the hammer?
Due to the nature of the very forceful impact of the hammer on the star drill, there is likely to be some metal fatigue leading to the shaft of the star drill becoming uneven or bent, so by rotating it one is able to compensate this uneven stressing on the drill, hereby prolonging the life of the drill due to it remaining straight and true. You rotate the star drill after each blow of the hammer to release the broken debris that has broken off from the last hammer blow. If continuously hitting without turning, the debris would be impacted in the hole and the surface cutting edges on the star drill would not reach a new cutting surface. This is why a hammer drill will hammer and turn at the same time allowing a fresh cutting surface to appear while removing the broken debris.
