THere are stud finder/detector with 'live wire' detector. The live wire emints small amount of radio wave, which ewill be detected by the the specific stud finder. Mmm.. try use portable radio AM. and try put it near live wire.

Nowdays, the pipings are made from PVC, which also quite difficult for the stud finder to find pipes behind it. The highter grage Bosch detector can 'see' the PVC pipes.. but... it is big and ...expensive.

Usually you can see a drill bit sign and a hammer. Switch to hammer for wall.

1) Check your drill bit. You should use masonry/stone/concrete drill bit. Typical size is 6mm, and use the red 6mm wall plug.
2) Make sure, the drill bit is still good. Blunt or weared out drill bits makes the task in-efficient and dangerous. The drill bit may brake if you push too hard.
3) Set your hammer drill to (rotary+hammer_ mode. and starts slowly. Push until it starts to bite/dril.

Err.. are you find, it is hard to drill the wall , especially at the top/near the ceiling?

is the usual wall plug colour coded ?? if so then its something new to me

I just realized it recently when buying new 6mm wall plug. There are several brands, and have same red color for 6mm.

This links help to clarify it...

Thanks for the tips guys and here's my report.

One side of the wall was easy to drill through. I planned to drill several holes actually. One for curtain rod, the other two for fluorescent tubes. Another side of the wall was difficult to drill through. I stopped seconds after impact. It just seemed like a futile attempt. The impact done on the concrete wall = paper cut I got from flipping through papers.

Damn, was hoping I could save money doing it myself. Turns out I still have to fork out $$$ to get a handyman! But thanks for the tips anyway.

I seldom use wall plug now, I notice most of the wall plug sold in hardware shop only come with two size small and very big, so for medium holes is hard to find the wall plugs. I now use the old wood / bamboo chopstick. It hold the screw much better. Recycle and reuse

Yes... we have the SAME experiences ... Before I got rotary hammer, I always suffered when to drill into ceiling for lamp's fixing. It was almost not going into it at all. I already burned couples of the drill bits just to get a hole finished. Sometime, I gave up, cut the screws and wall plugs into half, and fixing the curtain rails. Guess what, it did not hold much longer... The curtain will falls down because not enough grip from the wallplug/screw. After I got the rotary hammer, ... everything is solverd...


So, you can save your money from now and get a good rotary hammer for future use. You can help your neighbors, friends and family members to drill holes in their home, if you are not using it, and your experience also can be gained. As I said, don;t just lend it to them, you do the drilling for them...

Thank you.

Added on February 27, 2012, 4:22 pmI only use 6mm, red plastic wall plug, unless, the specific sized wall plugs and screws are come together with the things that I want to mount to the wall.

I really want to try, TAPCON, the self-tapping screws for concrete... but, I don't know where to buy some

Sometime i need 8mm, and 10mm. This to hold some big bracket. But can't find the correct wall plug. Also sometime I drill bigger hole by accident. The chopstick come save my days

Like when installing a pipe holder (like C clamp), i need to drill 10mm, and put in some woods and hammer the C clamp in to secure the pipe. Again chopstick some save my day.

I have not see any TAPCON, only now I know such things exist.

Yeah, it would be great to own a rotary hammer. Then I wouldn't have to get ripped off by untrustworthy handyman. Might get a cheap china-made one in the future.

By the way, I think I would hurt my male friends and male relative's ego if I started offering to help them do home improvement stuff!

Aiya... don't think like that la... Rotary hammer make concrete drilling much easier. Even my wife can do it by herself.. You can share your experiences awith your friends and make them get the rotary hammer, and ask them to do the drilling for you... heh eh he ..

Just brought myself Makita HR2470 last night..
Did not test it yet, but already can feel the 'power'.
(maybe i'm too excited)

any one know which brand is better to wheel cutter to cut mansory walls?

"cut" ... any diamond cutter would be good... just make sure you diy some dust catcher or suction

the amount of dust/fine particle generated is damn alot

fyi : your talking about "wall chasers" right ?

Yes wall chaser. I saw einhell wall channel cutter some what similar like wall chaser but max width is only 26mm for rm560. i think of using diamond wheel cutter instead since we need to cut wall more than 26mm width.
