I bought that same drill recently in order to chisel up about 500 square feet of ceramic tile from a concrete slab. It held up well even though it was in continuous use running in hammer mode for hours and hours at a time. I was prepared to consider it disposable but I'll hang on to it. Only thing I had to do was put some good synthetic grease in it. The stuff it's supplied with over heats and breaks down after about 30 minutes of continuous hard use. You could feel the gearbox begin to overheat and get a little noisy until I swapped out the grease. If only drilling holes I can't imagine it would ever be a problem though. The drill will take any SDS bit.
