rotary hammer drill is damn powerful yo. I bought a relatively cheap wireless china brand for RM200+ at lazada and was surprised at how powerful it is. But it only last me 1 year old plus. Now (bought it maybe 4 years ago) I can still use it, but have to take the battery out and in again every few seconds when I drill inside a wall, else it will just not run. At first I thought it's battery issue, but after changed a new battery the problem still persists. I asked chatgpt about it and it said it's common problem with the chips inside cheap drill. So if you guys have more money, just buy original makita brand. it will last you several years without any problem

buy corded Rotary Hammer Drill

no brand around rm8x-1xx

branded like bosch makita around rm4xx-6xx

if occasionally use jus buy no brand.

corded Rotary Hammer Drill is more powerful than cordless and less hassle worry the battery need replacement after year of uses

Buy Bosch rotary hammer cordless drill, I can safely say it’s one life time purchase if not heavy use like just diy for home fixtures.

The one Pro GBH180 LI, I have dy 12 years, still working fine.

Don’t buy cheap ones

GSB120 only for light use, can drill hole on cement but very slow and drain the battery fast

That's a great question! Drilling into a cement (concrete) wall requires the right tools to make it simple and easy.
The simplest and most effective way is to use a Hammer Drill with a Masonry Bit.

edit typo supposed to be gsb 180 li isn't roratary hammer, GBH 185 li is a rotary hammer. Like user above said it expensive for occasionally diy projects. Unless you have lots dedicated project and it's your hobby go for it.

With all the current precast concrete wall and tiling, 120 tak bole la waste money, go for the one I use pro GSB180 LI. Accuracy and hole precision damn neat and satisfactory.

This should be a one time buy for your life time diy
