What is the drill bit of the percussion drill, please?!

The diameter of the drill is in units.
Used of natural stones or concrete. The impact of drilling work in a drill chuck adjustment knob, adjustable normal electric drills and impact drills in two ways. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, but the impact is far less than the hammer. It is not suitable for reinforced concrete drill.
