Drill operated by compressed air, used in mining and tunnelling, for drilling shot holes (for explosives), and in road repairs for breaking up pavements. It contains an air-operated piston that delivers hammer blows to the drill bit many times a second. The French engineer Germain Sommeiller (1815–1871) developed the pneumatic drill in 1861 for tunnelling in the Alps.

I think that means it runs on compressed air.
