I have a rotary SDS Bosch Bulldog. Bought it used and it would have been worth the money even is I had purchased new.
I was going to be doing some work, and I looked at Hilti ($$$), the Bosch Bulldog model
Miss The Pontiacs bought, and then I stopped at HFT to see what they had.
Recognizing that the amount of work I was going to be doing was several days of demolition and then construction, and that after that, my need for the tool wouldn't be frequent, I decided to buy the HFT SDS-MAX (120 volts 8-1/2 amps) and their carbide-tipped drill bits, and a set of several demo bits of different configurations.
The cost of the HFT SDS-MAX was <$90 w/the at-the-time coupons, and the two sets of drill bits and demo bits was half of that, maybe a bit-more. Call it $160 out the door.
The HFT SDS-MAX tool worked like a champ, as-did the bits. My plan was to use the HFT items, and if the tool gave me any issues, I'd return it and buy the Bosch. I didn't need-to do that. I've had it at least a couple of years now, and when I need the HFT, it does whatever I need it to do, quickly, without fuss, extra effort, or breaking.
If I was going to be using it daily, the Hilti has a good reputation for ease of use and longevity, but the Bosch is cheaper. However for my needs, I worked that HFT SDS-MAX all-day for several days, and then occasionally since, and it's never not done what I needed it to-do. I did buy a SDS-MAX Bosch wide-spade bit, for a spare, but it's been sitting unused in its OEM wrapping since I bought it.
The HFT rotary hammer-drill with its switchable action has proven to be capable of doing the job, at reasonable cost, and reliability. One tip, be-sure to grease the flutes of the bits in the chuck, to ensure proper action.
I have a Milwaukee 1/2" impact drill, corded, I've had for many years, I bought it new, and that's what I use for smaller fasteners into masonry, like tapcons.
