Yup I bought a Stanley STEL503K to do just exactly those stuffs. RM 290 from Lazada after voucher.
A contractor that I engaged to put up a partition wall in my house even used a Boyai rotary hammer from Mr DIY and they work just fine.

It's a worthwhile investment for me, I'm doing some DIY home reno at the moment and was having a hard time drilling into ceiling concrete with a GSB16RE which is an impact drill.

Decided then to get this Stanley and it took few seconds for the same depth and drill bit size that took almost a minute on the impact drill. Your hands feel less tired and less vibration also, and it's actually not as noisy as an impact drill, also the holes are cleaner because u spend less time boring the hole.

Only downside is, they're heavy compared to an impact drill, but the weight penalty is offset by being able to finish ur drilling much faster

Most of the rotary hammers, including the STEL503K, can do drill-only, hammer+drill, or hammer only for light chisel work (I haven't tried that out yet), just bear in mind that they take SDS+ drill bit, not the usual rounded drill bits that impact drills use.
