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

So there's no all in one tool then? Have to get a rotary drill for concrete and another drill/driver for basic stuff?

hammer got two type.

QUOTE
If you need to drive a screw into concrete, you've got two choices. Either you use a large rotary hammer or a drill driver with a hammer-drill function. Both tools pound the bit while it spins, pulverizing concrete, but the two differ in the mechanisms that do the actual pounding. In a rotary hammer, a cylinder of air is compressed by a piston, which in turn beats the bit. In a hammer drill, two ribbed metal discs click in and out against one another, causing impact. Among tradesmen working daily, rotary hammers are preferred because of their superior strength and shock-absorbing qualities. For the occasional user, the large, bulky tools are often overkill—a powerful all-purpose drill driver with a hammer-drill setting makes more sense.

Thanks for the info!
So, just to know... the GDR 1440-LI, does it have hammering? Here's the specs I found;

Max. Torque 130 Nm
Bolting capacity M4 - M14 standard bolt
No-load speed 0 - 2900 rpm
Impact rate 0 - 3200 bpm
Battery voltage/capacity 14,4 V / 1.3 Ah
Tool holder 6.35mm Hex
Charging time 60min
Dimension (length x height) 153mm x 231mm

Is that impact rate that hammering function you're talking about?

Ok, Thanks for the info. Maybe I'll get a basic one 1st before getting rotary drill.

What do you think of the GDR 1440-LI? Good Investment?

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..

i think got some torque and RPM difference.. but i use it for drilling screws directly into metal so use driver is ok (to hold hex screw tip)

if drilling with drill bit then obviously use chuck type , which i already got the 10.8V makita for those type of application

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

Probably rarely gonna drill holes in concrete. Even so will probably drill holes to screw in for shelves or racks and picture frames and such. Nothing too extreme.

You reckon still need to get a rotary?

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.

Thanks for the info! Will keep an eye on the hammer drill when I need it!

Between the GDR1440 and GSB10,8-2-LI... Why do you recommend the latter? Is it because GDR1440 overkill for screw driving? or it doesn't fit with my usage?

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

Hi there, I am new to here but just a thought, if buying cordless lithium battery range, seems like bosch lithium batteries do not have cell balancing circuits internally. Basically the charger considers the battery is fully charge when the battery start to heat up. Newer generations seems to try to correct the previous lithium battery generation but still not as good as it should be. Balanced charging is very important for lithium batteries if you are heading towards that direction.

Thanks so much for this info. Really helps a lot. So I guess its the GSB10,8-2-LI then. Gonna wait a while for the impact drill.

Just wanna share my diy experience:

Recently had to do some drilling for my tv wall bracket and other bathroom accessories. Went to hardware shop wanted to source for used rotary hammer drill. It's about 200ish for makita or bosch. No warranty.

But shop owner suggested to get brand new cheap one dat costs less than rm200. At least he said got warranty for few months.

So I bought it, and man it did all da drilling job I needed to do with much ease and effort. (fyi, i was using my impact drill at first. But gave up.)

Blue one da new rotary hammer drill.

Orange color my impact drill.

i would rather get the used refurbished makita if I were you
it will probably outlast the no-name brand

anyway thats what I said too....impact drill is a waste of time.....go straight to rotary even if you only gonna drill a few holes. that few holes is enough to kill your mood to continue the DIY
