Is it cheaper if you just ask the contractor to do it for you? Instead or renting and buying the drill.

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

Strange. Why the Makita and bosch no warranty ?

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.

Yes.

Get the gsb 10.8v and match the GSB10RE. GSB10.8 can't use for wall. Only for drilling and screw driving.

Cordless for wall is slow.

Those 18v cordless impact drill can drill concrete. But don't expecting it as powerfull as cord type and do the job fast. It is not as cheap as cord type too.

You want power cordless ? Nah --> http://www.makitatools.com/en-us/Modules/T...x?Name=HRH01ZX2

All this power tools here are running on 18v battery. Some require 2x battery to get the power to work.

Cordless power tools are getting popular. Wait a bit longer for the technology and you get a more powerfull tools. It is coming. Price too will get cheaper. But not at the moment.

You can't see much this cordless powertools here. But it already getting common in western. The price cheap for them. But not us.

You better leave your wallet at home before go in this store.

You will end up pokai when coming out.

See the top left got a lock? Flip to back, poke that round thing. The lock open.

Break it also can. Not break it also can. If not break it, it will be tricky to open it.

Sometime I also forget and take sometime to figure out how to open.

Wow, nice. How much damage?

Get a block concrete and start training. Train and train till fill confident to handling.

Later he get high and torn down his whole wall. than start to attack the beam.

If you just want to assembly some wood and screw something, this 1 is ok. Drilling metal have to be smaller hole, thinner and a bit longertime. Max speed is only 700rpm.

The torque is not much. Only 7.5N. Generally torque for screw driving is around 4N for a diameter of 4mm.

For battery, maybe not lithium.

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.
