No, the drill is hollow and you pump water through. Also helps to flush out the dust. Except when drilling Aerated concrete or something luke that, then you juat get your bit stuck.
Neat… I always assumed they used the same lube as machining… but I guess you are more interested in keeping the bit cool opposed to the material, where machining is sort of the opposite.
