The hilti is a lot more money and tbh if it's going to be abused I'd get the bosch and buy another when is done.
That's my opinion as well. With my 240v sds I know I am going to use it to drill well over what they say you can so I go and grab a screwfix catalogue and look what's on offer at the time. I've only got through 5 in 15 years so that's not too bad for probably not a lot more than £500.00
Don't buy dewalt though I've burnt 2 out, my Bosch I have sold on 1 when I got fed up of lugging a transformer and the other I sold as I had it for a fair few years.
