wow, i really impressed by the Rotary Hammer mode, damn fast...

Can sand, but to sand concrete it need special material. Sand paper will not last 1 mins.

Impact drill
- cheaper option
- good for DIY for home user
- best budget for DIY

Rotary hammer
-get the job faster cause is hammering while drilling
-more expensive
- best suited for installer and professional users
- tiles , either very slow speed or use special method

I relied on Bosch product cause Makita/Maktec is cheaper but not reliable as Bosch does.

I recommend Bosch GBH 2-26DRE or else DFR model for removable chuck.

damn the makita i bought seems like the best toy i ever bought

tested it out today drilling a 12mm hole effortlessly...

chiseling out a hole using the hammer only function so easy and effortlessly.. (chiseling out a hole on red brick wall)

damn its the best tool to have.. impact drill sorry i have to abandon you already..

once you go rotary you can't go back lol

I use my makita till now white color, need to take blower to clean it. Use too many time. Another good investment is variable speed grinder. Diamond cutter + rotary make conceal cabling so easy.

After makita, I brought variable speed grinder, and dig back my old sander, Bosch spray gun. Got myself a set of polisher for marble / cement / granit.

if they can find a way to make it work quieter it would be awesome

Great to see and read some more reviews/experiences here.

Quieter? Yeah... but, it's still sound good, just like.mmm... yeah the minigun



BTW, for hole drilling, it just took less than 10 seconds, compared to more than 30 seconds of whining and screeching sound of the impact drill, and I prefer the minigun's likes sound of rotary hammer.

After finish using it, make a practice to wipe off the dust and clean it before store it. Also, put a small amount of grease at the driil/chise/bulpoint bit's grooves before inserting it to the chuck. I already have my rotary hammer for 6 months, and it is like new, even after making about 100 of holes in concrete.

Aaa.. you felt the same, that,we are not going back for the impact drill. 12mm ? It is still a small hole, compared to the H2470's full potential, handling up to 24mm masonry drill bits. In my case, most of the time, I only use 1/2 of the my rotary hammer for more controllable drilling jobs. At full power I need to add more pushing force to keep the rotary hammer from 'bouncing'.

Durability: Since most of the readers here are DIYers, and some of us have very tight budget, buying a good and cheap rotary hammer always a priority. Remember we are not making hundreds of holes EVERYDAY, , then a mid range priced rotary hammer is always a good choice. This is why I bought Makita HR2810. There are several other brands, such as Hitachi, Hilti and Dewalt which are also a good brand too. Don't forget that, rotary hammer has to be built to last. and not being destroyed while destrying/demolishing building into dust.

Last week, I used the rotary hammer + bulllpoint bit to break and remove some stones, bricks and dried cement in my lawn yard. Yeah, my lawn yard is like a waste//leftover dump site underneath the soil. I also use it to loosen up the soil to make digging much easier.

Ok, I did another experiment using roraty hammer.
How fast to drill a hole into a WOOD using rotary hammer + masonry drill bit, compared to an impact driver using auger/wood bit? Hint: Ignore the result quality.

Thank you.

Anyone experience taking out Tar road? My drive way have a raised tar road "Thanks to the big tree root", now i want to remove it and later ask someone to tar it again.

Since the tree's root already made the bump, IMHO, it is not that difficult to remove the stones. Road is made from a stones glued together by tar, and I don't see any problem to remove it with chisel or bullpoint. Take a try, and report it back here.

Or, how about using 9" grinder with stone/masonry cutting wheel, this might can to the trick.

well if the bit's pricing seems to go up exponentially with the increase in size.. not sure how much would a 24mm bit cost

I only have 4" Grinder, where got 9" Cut tree meh.

24mm for DIY use? wow, unless you are a plumber or a builder. The price also depends on the bit's length, material and technoogy. Mmm... I think you can get a cap ayam 24mm for around MYR50 or less (I might be wrong) ... If you use 24mm often, get the Zentro or 4 cutters type bits, for durability and better drilling performance.

yeah heard about those bits with 4 cutters on the head... the bosch one cost a BOMB...

just curious.. does jalan pasar sell this kind of hardware stuff ? , can't seem to find a proper place that has a well stocked inventory of diy stuff...

That type of drill bits expensive, unless you use it very frequent on the same size than is good to invest one. Else normal SDS bit will do. Not that you make 100s of holes a week.

The Bosch 4 cutter's drill bits such as the X5L serie use full head carbide tip, which is very tough and can drill through a rebar steel in concrete, and also long lasting. That's why the drill bit is very expensive.

Most of the hw shops have some drill bits, up to 32mm...or you can order one from them.

How much did you guys get the Makita 2470 for? I'm looking to get some sort of drill too.

You can find the HR2470 price in this thread...more or less than MYR500.

yo out there, I was at an electrical shop when I noticed
that there was a shop selling all sorts of power stuff
including mowers, pavers and makita stuff! Didnt have enuff
time to xplore cos of appt dat day but will do so nxt week...

Its in Paramount Gdn, PJ beside the Giant supermart which was
a cinema before. On a 1-way street with a large Makita signboard.

Just for your info....and expedition....

Know that shop, from outside very run down. Don't stock much drill bits. They do have many new and old power tools. Is same row of the Aquarium fish shop.

Where can buy drill can suck the dust together.? Found it on youtube, it queit impressive. Suitable for indoor use.
