Three questions.
1. What wall material? Concrete/RC/AAC block or just normal red clay bricks (exclude concrete beams)?
2. Wall plug size only?
3. Cordless cannot do with this budget if don't have existing 18V battery and charger system. Tool only (GBH180LI sans battery and charger) is 350-400 for rotary hammer. Full set with 4AH procore battery and fast charger 777.

This makes life easier.

Bosch GSB (B for bang=impact) GSB180LI will suit your needs.

The machine (solo tool only) is about 220-230

About 450 for complete set with briefcase.

About 500 for complete set with the fisherman toolbox and extra drill/screwdriver bits.

I would suggesttake the cheaper one and add the milwaukee impact bits is better idea.

Do not get the GSR (R for reversible, NO impact function) =  instead

It'll work up to 10mm in bricks (masonry) according to spec sheet.

Have the same myself, just on bigger battery shared with cordless rotary hammer (for concrete), but this works well for 6mm wall plugs in brickwalls.
This has also been abused as a "mini grinder" to polish out socket backbox holes in brickwalls.
Usually for me I use it for tile bits around 6mm, it works well (as tile bit cannot use at >500 rpm).

Just because it is quite new in this power tool arena I guess even though brushless motor has been around so long already.

Anyway, the cost of part in brushless is more expensive than brushed type.

In my opinion, not worth to pay for the price now unless you just want to be able to tell you have brushless power tool and don't know where else to spend your money 

It depends on usage pattern. For commercial use or home use actually some EC brushless like the GBH180LI cordless i remember getting it (EC brushless solo) for approx 350 to 360 bucks as sifu ijan recommended so it didn't really cost more than the outgoing brushed model i would say?

In your case since the differential in price 200 bucks..not worth lor.

Between the two
I believe the higher priced tool has a metal chuck, TBH for fixing screws like wall plug size, drilling tile bits, mixing paint, the GSB180 is already more than enough..I usually run at 1-5 lowest setting to avoid overtorquing the screws too deep in the material (kitcab), driving into 1.75/2" wall plug maybe around setting no.5 (highest is 20) on low speed gear. The price diff is almost enough to buy another GSB180 solo unit 

If you run this in screwdriver mode most of the time it is plentiful enough. Important to get impact rated screwdriver bit like the milwaukee shockwave 10 bucks per pc, less prone to snapping the screwdriver head off. Comes in shorty 65mm or 110mm length. For fixing shelves 110 easier. For tight spot 65mm minus off the 1in in chuck it makes for a shorter tool but its not very flexible for non head on (as in not aligned 90deg perfect angle) application.

The only time where the plastic chuck (still can buy replacement chuck head) may fail earlier when it is abused as a wannabe grinder (sideways movement polishing of the wall for socket backbox); or if you have hard concrete wall (brickwall is easier to go thru) and abuse this for weeks as an impact drill whereby a rotary hammer will do the job easier.

Normally the the with metal chuck has higher torque. If the price is not much different, then I'd go for higher torque.

I also tend to buy higher spec tool if I think the price difference is worth the the additional feature or spec which I may not need to use now. I bought lower power drill thinking I may not need higher power, but in the end I end up buying another one with higher power with hammer function. Then I bought a rotary hammer with ability to chisel as well. Then I bought cordless 

I still found each one of them has own use for different situation and requirement.

In thins case I'd say I'd go for the GSB 18V-50 even if Rm100 extra.

I have no idea the price difference here but most of the time the price difference due to what the package provided like casing additional accessories. Need to ask the seller. The picture is just trick in business 

Sikit sikit jadi bukit they said 
All the ones below in my collection come with the briefcase looking case, except circular saw and grinder papeŕ box only.
There are some variants coming with fisherman box.

Power Tools
Bosch GBH 2-24 DRE rotary hammer 490
Bosch GBH180Li cordless rotary hammer(solo tool,4AH procore,fast charger) 777
Bosch GKS7000 circular saw 335
Bosch GSB180-Li 229
Bosch GWS060 angle grinder (with grinding discs) 115
Bosch grinding discs 10
SDS Drill bits for rotary hammer 28
SDS 22mm bit 44.8

Depends also if there's a bigger toy for more heavy duty work as well. In its class as a 18V drill driver I would say it works very well (GSB180). Most contractor video also get by with the GSB120 (those china amoi electrician) https://www.facebook.com/watch/?v=211347934082616

@blanket84 , torque is 28/50 Nm in the 18V 50 vs 21/54 in brushed GSB180.
Not much diff in actual usage, but you will get metal chuck (which I believe can be replaced) and brushless motor only.
Torque almost similar but the low torque is higher by 30pc in low gear.
If usage more as screwdriver I think GSB180 is plentiful already, use the money for bigger battery if needed.
Coz based on experience driving 2" screw I didn't need to max out the torque even on low gear 

It also depends on your strategic planning. If power hungry stuff e.g. lawn mower/cordless grinder/cordless rotary hammer are not in the collection master plan anytime soon, then any 1.5AH also will work fine.
Just for reference - Cordless rotary hammer need min 3AH. Drilling about 20 holes 2" 5.5mm in RC wall already took up 1 bar from 5 bar of the 4AH procore.

If you don't have concrete wall to worry about - Drill driver should be perfectly fine with the 1.5AH or 2AH (lighter battery).
3 and 4AH weight similar but weight is more than the 1.5-2AH sizes.

Per https://www.cnet.com/home/kitchen-and-house...cordless-drill/
It appears that for 1.0AH alone you should be able to do these for sure. The 0.5AH not included as "reserve capacity" 

Number of 3-inch screws screws driven into hardwood ("balau" or similar) per amp hour for 18-volt brushed drills. ~ 125x

High torque Number of 1-inch wood spade bit holes bored per amp hour for 18-volt brushed drills. ~ 20x

For my GSB180Li on a 4AH procore (my only battery ) it hardly deplete the battery at all in screwdriving use. Drilling 20-30 wall plug 6mm holes in brickwall should be easily doable on a 1.5/2.0AH.
Would be fun to see a pic of his tools collection  if its convenient lah, no worries. Just my curiosity.

Bought online. Should be brushless based on the sticker

Ahh my apologies I messed up the pricing abit, should be RM395 c/w a set of free Makita bits and the briefcase.
Coz that time they had a promo for Grabpay I got to claim the RM80 grabpay credit for GBH180LI back then
Idk why in my mind it was ~350-360 worth (I think I must have discounted away the briefcase and set of free Makita bits)   apologies!

[attachmentid=10830664]
[attachmentid=10830665]

All in all gross 768 after some free shipping etc. Actual value undiscounted should be around 777.

[attachmentid=10830667]
from the 475
GSB180LI w/ fisherman box solo is 229
balance 246
for one piece 2AH its already 207
for set of 2pc 2AH and one charger its 379 https://shopee.com.my/BOSCH-18V-2AH-STARTER...00441.289836963
so for your case looks good

I think this is quite a good deal, there may be some TnG credit promo to claim (current ongoing) IIRC.
For the solo unit nowadays very expensive already. So it may not be so worth to buy piecemeal like my rotary hammer, 2021 combo meal cheaper

Seems like everything went up RM50..
GBH180 rotary hammer solo also around 450 nowadays..
GSB180 impact drill solo was 219/229 (briefcase/fisherman) last year.. was 180 but earlier seller I ordered from didn't want to ship out from March till May

Fisherman box itself also worth RM50 on its own coz its a very nice toolbox for the price

For your question..
usually I use CYL-9 for tiles https://shopee.com.my/MAJU-Quality-CYL-9-Ce...37111.192248145
You can also use Makita glass bits but cost a bit more https://shopee.com.my/MAKITA-GLASS-DRILL-BI...6835.9004738524

It will need 5 min, use slow mode (gear 1) on your GSB180 on drill mode only (without the hammer!)
Slower you go the longer the bits last. They wear out crazy fast /break easily if you rempit them.
After the hole passed the tile already, change to the cheaper masonry bit, and impact mode the mortar behind the tile.

It looks like an improvement over the old CYL 9 ceramic, seems to have more than one cutting edge so its like a mini TBM (tunnel boring machine).
Shank wise being hex shank can go into any drill or impact driver which kinda makes good sense in terms of maximising tool compatibility since to work this tile bit you just need something that rotates (NO impact).

The only potential caveat I see in HEX-9 is the tip is not as sharp pointed as the previous CYL 9, so care need to be taken to hold the drill precisely otherwise it might skitter horizontally, you can solve this easily with masking tape and drawing a dot for the hole.

For all tile bits the heat kills the bit so although they say cooling not required, you can make a single bit last longer if you constantly cool it with a trickle of water (if it doesn't make a mess such as in bathroom, no issue with wetting the place). Bits can be used dry mode also but don't rempit them until smoke come out. My POV is either run it pure wet all the time or just pure dry mode as frequent hot cold hot cold stress the bit tip and more prone to cracking in the case of CYL-9.

Hahaha it does "save money" especially for smaller jobs like install shelves and curtain rails. I think I made enough from a few small paid jobs (neighbours and friends) to pay for the rotary hammer itself as compared to calling contractors which naturally won't be too inclined to show up for minor minor jobs.

For Ikea kitcab as I did need to invest in additional tool i.e. circular saw to chop the countertop and cut out the sink hole it was just over half of what the usual installation fee circa RM600 would cost.
Ignoring the cost of the rotary hammer since other jobs already paid for it

Whatever ceo684 is charging, I offering 50% less  :thumbsup:
