    Investigation on drilling of two alpha beta titanium series. Ti-6Al-4V and Ti-5Al-4V-0.6Mo-0.4Fe was conducted using WC/Co carbide drill. Tool life, tool failure mode and surface integrity were examined when drilling both alloys at various cutting speeds. Results showed that Ti-6Al-4V exhibited a more superior machinability property in the drilling tests when compared to the Ti-5Al-4V-Mo/Fe alloy system. The tool wear progression when drilling Ti-6Al-4V was significantly lower than that of Ti-5Al-4V-Mo/Fe. Non uniform wear and chipping on the dril were the main tool failure modes when drilling both alloys. Examination on the microstructure of the sub-surface of the drilled surface, indicated that both materials suffered significant plastic deformation at all cutting speeds.
