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?

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...

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

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 ..

Nice, now we don't any problem to find Makita's power tools. Cheapest price,? Aiya, just call the shop's phone numbers la.Not cost much to to call laa..

HR2611FT... wow... this is the latest Makita corded rotary hammer. ... I already saw the announcements last year in Makita Japan website.

Honestly, I never expect it going to be in Malaysian market that fast.

Anyway,, thanks for the update.

In my case, I called Jasakita, and they pointed me to the hw shop address in the first page. I called them, and they have HR2810 and HR1830, which both I wanted to see before I want to buy.

I think all the official Makita resellers can be helpful. If not, complaint it to Jasakita.

HR2611F, English



HR2611F, Japanese

I like to have the dust cup, which is a standard accessories for Japanese HR2611F. I also like the auxilary handle, with the depth gauge stopper. Wondering if it can be used to my HR2810.

Added on March 15, 2012, 10:28 amMy HR2810 does not has the AVT (Anti Vibration Technology) or spring loaded handle mechanism in HR2811F(T), but, IMHO, the vibration is still low, and no complaint about strain or pain in my hands, even after continuously making 20 holes into concrete block.

I think it is about the same experience with HR2470, GBH2-26 or other rotary hammers. Other rotary hammer's users can add and share this particular experience here.

Thank you.

How tight is it? Give us some measuring..

The smallest rotary hammer, I ever pick is, Makita HR1830. with size, 279mm x 66mm x 208mm. IMHO, it just as small or a bit bit longer than my impact hammer drill.

Yeah, there are Panasonic compact cordless rotary hammer and Rockwell H3 rotary hammer...

Wow.. that kind of small space... Not sure, what is the best solution for it.

What I can think is... right angle adapter + impact/percussion adapter

Added on March 19, 2012, 11:04 amYes, I like the Marcoza wall chaser too. Very cool tool. Why not you call the distributor and ask them how muc it is, and whether they also have the rental plans.

Aha... the diamond cutter + right angle adapter... Good idea...

Not just pro, he also looks OTAI (old timer), or DIY sifu.

Thank you for the tips. My house is near UKM, Bangi but, I rarely go to Kajang town, because the traffic is quite busy and quite difficult to get parking slot.

The power tools pricing is very reasonable and cheap. I may go there for window shopping.

Hope you can share your experiences with your new power tools here.

My advice to new power tool's users...
Always start SLOWLY. Sometime drilling at lower speed/RPM is more effective than at higher speed/RPM. Increase the speed until you feel it drill smoothly/easily into the wall.

Thank you.

Makita HR1830 ... is the smallest corded rotary hammer I ever hold in my hand. At 18mm in concrete, it is more than enough for home fixing DIY. It's weight 1.7kg, or it is about as heavy as 1/single brick. I think it is very easy to use, especially overhead drilling into ceiling.


The L or D shaped rotary hammers are quite rare in Malaysian market, and only high end or high power rotary hammers have that type.

Thank you.

The main difference is the size and WEIGHT.
4 kg vs 1.7 kg
Even my 28mm HR2810 is much lighter at 3.2 kg. Seriously HR1830 is very compact and I am sure ladies also can use it with ease. Anyway, before you buy, try to pick them up and then, make your decision.
