We present measurements of Collins asymmetries in the inclusive process$e^+e^- \rightarrow h_1 h_2 X$, $h_1h_2=KK,\, K\pi,\, \pi\pi$, at thecenter-of-mass energy of 10.6 GeV, using a data sample of 468 fb$^{-1}$collected by the BaBar experiment at the PEP-II $B$ factory at SLAC NationalAccelerator Center. Considering hadrons in opposite thrust hemispheres ofhadronic events, we observe clear azimuthal asymmetries in the ratio of unlike-to like-sign, and unlike- to all charged $h_1 h_2$ pairs, which increase withhadron energies. The $K\pi$ asymmetries are similar to those measured for the$\pi\pi$ pairs, whereas those measured for high-energy $KK$ pairs are, ingeneral, larger.
