We demonstrate a sub-picosecond 1-kHz femtosecond X-ray source with a well accessible quasi-point size (10 $\mu$m diameter) providing Cu, Ni and Ti K$_{\alpha}$ emission with a maximum flux up to $7.0 \times 10^{6}~phot/srad/pulse$ in continuous operation. A new geometry, which essentially facilitates the adjustment of time-resolved measurements and diminishes the temporal jitter between the X-ray probe and the laser pump pulse is implemented. An upper limit of 500 fs was measured for the duration of the X-ray pulses.
