My house was built using hard burned red brick (which is so damn hard) thus Makita HR2470 does the job efficiently.

Then I bought GSB1080v cordless. It does the job same like makita but a bit longer and u need to press harder. Certain areas I cannot drill to expected level, makita finish off the task..

However, when dealing with new house (mostly white brick), my GSB does the drill job easily like kacang putih..

So for me, u need to see type of brick your house have. Decide from there.. We can recommend powertools but the person who use it knows better which tools suitable for him/her..

I personally nowadays prefer GSB than Makita.. Lightweight, compact and flexible.

Depends on the wall you want to drill.
Normal landed house that used red or cement brick usually a hammer drill will do.
Concrete wall, hammer drill also can drill but it will take longer and you need to push harder.

Unless you need to drill into the support beams which are very hard concrete then you will need rotary hammer.

I use bosch GSB18V hammer drill and it can drill 5-8mm hole in both brick and concrete. Just concrete will take longer time.
