Brought this set 2year ago for rm290. Model gsr10.8v-liq bosch. Use for screw and drilling till 4mm dia. Bigger drill no torque. It have torque adjustable 1-10 (probably max 10kgf/cm) which good for screw. It come with a torchlight which you can use the drill battery.

seems like bosch prices quite stable... or hovering in that range

Ya, one battery sufficient for DIY, but sometime you need the job done in quickly and urgent, I don't think one battery is sufficient. Because you need to wait the battery fully charged in 30 minutes, but really fast compared to
older technology, NiCa which need more than 1 hours


You mean this type of chuck ( 1/4" Chuck ) :



I get the picture from lelong.com.my

Sure can , but the drill bit a bit difference , it must have 1/4" hex shank because the Bosch Impact Driver only come with 1/4" Chuck. But the drill bit also more expensive compared with normal drill bit , I bought the drill bit before and just few hardware shop selling it.

The 1/4" Shank Drill Bit :

Or you buy 1/4" Hex Shank chuck like what Eng_Tat Mentions.


Where did you bought it ? Taobao ? Because this model only available at China

Ohter tool which can drive screws... but not as efficient as impact driver.
In this clip, I showed how I drill holes into wall with ceramic tiles.

But the special thing is, I am using rotary hammer with 1/4" hex adapter to use my impact driver's screw bit. A bit awkward and difficult, but it can done...

Enjoy

Yeah. Like that.
I assume you will be using normal drill bits?

What happens when the impact mechanism kicks in while drilling?
Also will the drill bit hold steady when spinning or will it "wave" about (like the screw bit in bahathir's rotary hammer video above)?

If you use the chuck then you can use normal drill bit

If without the chuck , you need to buy special drill bit that designed for 1/4" Hex Chuck.

But the risk , when the drill bit stuck during drilling a steel , impact action will make the drill bit break into two parts because the impact driver will start hammer if got somethings stuck. I think it will create wave or vibration because you already add a big things on the impact driver and it may create more wave or vibration during high speed

Not sure what is the price now for this. I guess the price is reasonable.

Agreed. Impact driver's impact mechanism gives extra TWIST or torque to spin the bit. Remeber, impact driver torque is much bigger than normal drill driver, and the the chuck's jaw cannot grip the cylindrical shaft's bit. Sometime, this extra torque impulses also can loosen the chuck's too, especially in reverse mode. So sometime, better get separate specialize tools for greater result. I know, as a DIYs, we have a limited budget, so, getting a good tools which last longer is very important.

In my case, masonry/concrete drilling is a very tough to the tool. You may get 3 in 1, or 4 in 1 cordless impact hammer drill driver, but, really, how much you achive with this tool? the 4 in 1 cordless tool, exmample BTP140, is very rare in Malaysia, and it may cost you MYR2000 or more. Hey, I bought Makita HR2810 rotary hammer + Makita TD010F impact driver + Makita GA4030 angular grinder, and it still cost HALF of the Makita BTP140! Yeah, sometime conveniences cost more than performance. Yeah, different people, different needs, so up to you to decide which tools are sutable for your need.

Thank you.

Ya, for DIYer. Price ( Cheap ) and durablity ( Last Longer ) is more important. For DIYer, most common tools is Rotary Hammer, Screwdriver and Angle Grinder. If you need to screw a lots screws, impact driver is the most suitable.

For me, portability and performance is the most importance because sometime doing small task at outside or on roof or other. Impossible to bring a 10metre to 50metre wire to outside or roof just for drill one hole, that why I bought a Cordless Hammer Drill.

But tools in Malaysia is the way too expensive, if you bought some tools from USA and send it back , it still cheaper than here.

Brought at jln taman tan yew Lai. I see few shop got sell this model.

If only they put in a switch to turn off impact action

Cheap and durability don't exactly go together.

Damn!
I need to do the occasional drilling but I also need to drive screws into some tough wood.
The wood is hard enough I can't hand-screw the screw all the way in.
I'd love to buy two power tool (power drill and impact driver) but have only budget for one.
I guess the power drill should be my first tool then.
Any suggestions for features I should look out for?

all your answers is here.. http://forum.lowyat.net/topic/2051914

I drill a hole on the hard wood. Slighty smaller hole than the screw size. That make it easy to screw in.

If you need to drive screws alot, impact driver is the more proper tool. Impact driver also can drill into wood, steel and plastic too, with proper drill bits. So, try the impact driver first.

I just added couples of youtube clips in posting #2 in this thread.

About the corded power tools: Since I am using my power tools around my house, which is not 50meters height, so with 2 10m extensions, I can get almost every inches around my house. Last time I installed an outdorr antenna IN the roof, yup, NOT ouside, but IN the roof attic. I mount the pole holder to the roof supporting frames wood with screws, using the corded impact driver. Another case, I drilled holes into the wall OUTSIDE, near my house's number for the instellation of the wireless door chime's switch/transmitter, using my corded rotary hammer. Yeah.. luckily I got power outlet points at the strategic locations around my house.

Nothing is bad about cordless power tools, but, if possible, I'll try to avoid them at the moment. Unless, I am doing the installtions on building sites where there is no power outlets in the reach, and it doesn't matter because, the company is suppying the tools to workers, NOT form my pocket money.

Thank you.

how's the signal quality ? won't it drop since need to pass through the roof tiles ?

Since the antenna has built-in booster, the signal reception is fine and as good as any outside antenna. A good thing is, it last longer because it is not exposed to heat, sunlight, strong wind, rain and bird's dung .. heh eh he.. The antenna syustem also can rotate remotely, so it easy to get better signal. Since is not outside of your house, it make more aesthetic looking house.

Try first,...

I wouldn't say "a lot" but certainly the need for screwing is more than drilling.
But if I had a good drill I'd guess the need to swiss-cheese my house would then increase by a lot.

What about a heavy layer of rain water on the tiles?

Just thought of another advantage to having your TV antenna inside is protection from lightning strikes.
