Oh I thought you wanted a driver.
What you need is rotary drill for concrete

hammer got two type.

Yup i bought two also

i think i have the same model in the workshop 14.4V .. this is impact driver (the head is hex to hold screw driver head) (i use it to drill blind holes into thick Aluminium extrusion for my projects)
there is another impact drill (head is using chuck to hold the screw drills and screw driver head)

yes it has impact function which can drill into concrete but slower and u need to apply some weight going into the concrete.. good for a few holes here n there.

in the video the 2nd drill that one is made for drilling concrete holes all day.. but its overkill for house hold use..

For Rm430 you can add another rm100 can get a rotary already. Cordless drill concrete better forget it. Even those plug in hammer drill also takes forever for one hole. Don't waste your money. Drill until your hand painful also cannot finish one hole LOL

For your simple job, just get a hammer drill. Like bosh GSB13RE or GSB10RE. It can drill concrete and wood and metal. But too powerfull for screw driving.

For screw driving, get the GSB 10,8-2-LI Professional. No need GDR1440. GSB 10,8-2-LI Professional can use for drilling metal and wood and brick. But not concrete.

Both is enough for your job.

Actually GSB13RE or GSB10RE is a must for any renovation or start a home for small DIY.

The battery running type is optional. You can use screw driver anytime.

1. GDR1440 is for contractor use which require heavy duty and long working time. Overkill for you.
2. It is much more heavy. Not suitable for beginner.
3. It have less function compare the GSB10,8-2-LI. See at the chuck side. GDR1440 mainly for impact screw driver. It can't hold a drill bit. And can't drill a hole on metal and wood. So it doesn't bang for your money.

The bosch my website is useless. Doesn't give much more information. It is difficult to select and understand for beginner.

You can take a closure look at similar thing here https://forum.lowyat.net/topic/2234276/+480

If not mistaken, the drill itself is same. But gsb500re is bundle with kits. While gsb10re is only the drill selling.

There is no different. Probably different country model no.

But you better get a higher model like GSB13RE. This 10re are not that powerfull drill.

I check on their website http://www.bosch-pt.com.my/my/en/impact-dr...-re-131432.html

Just go to any bosch dealer and check. Hardware shop.  If no stock, order from them.

GBM 13RE is just a drill function. Which is only for metal and wood. Doesn't have impact function for wall drilling.

The drill bit kena the some steel bar. You can't do anything but drill another hole. Sometime you would able to see some spark coming out. There is also possible that meet some hard concrete stone. 

Concrete drill bit good at concrete wear (grind wear) but not sharp enough for metal drilling. Compare both drill bit tip, and you can understand.

If you hit rebar, and really want to go deeper, you need to Change to metal drill bits, but you need a good bits to drill it. And spray some water regularly. But I don't advice to drill through rebar.
