i do not have a pic of it. so i'll just describe. basically, it looks like a excavator, except the end of the extended 'hand' is not for digging, but is attached with a driller kind of thing. but it is not for drilling holes, to be exact, it usually break concrete roads/floors such that a new concrete surface can be built again. don't think it is called a excavator drill.
is it this one its called uammer excavator
It sounds like it could be an excavator with a hoe-ram attachment. This attached where the bucket usually is and is operated off the hydraulic system of the excavator.
