so far no body here used einhell rotary hammer? i am thinking of getting rt-rh32. this can whack up to 3.5j. what do you all think ?

I just published another youtube clip demonstrating the rotary hammer's power. Yes, it is possible to drill into wood, but, the hole is not as clean as when drilled using proper wood bit. :


Impact Driver : Makita TD-010F
100Nm torque; 230 W

230 W vs 800 W of the HR2810 rotary hammer... But, wood is quite a touch material to drill . Compared to my previous clip, rotary hammer + 12 mm masonry bit can drill into concrete block in 4 seconds... but it took longer with wood.


Thank you.

Note: A new addition to my DIY tools.... the Black and Decker's Workmate 225, workbench... and.... Makita GA4030 grinder..

Added on December 2, 2011, 3:19 pmThe higher impact energy (3.5J) is more suitable for demolition or bigger bit's size usage. But, it will be much bigger and heavier, (5kg and above), and of course, more EXPENSIVE. Depends on your usage, the bigger rotary hammer may suit the purpose. Planned it carefully before buying it.

That is NOT a SDS rotary hammer. It is just a typical percusion impact drill, and performe just like any impact drill.

lol , your rotary drill on hammer+drill mode... sounds like a scooter.. hahah

just curious your using the normal sds bits for concrete ? to drill wood ?

care to share pic of your

It was in Rotary+Hammer mode, just what I pointed at in the clip. Yup, it may sound like scooter, because, rotary hammer uses piston to compress air and push the 'striker' to push the drill bit. In other word, it works similar to typical 2 or 4 stroke engine. Since I drilled into wood, the metal to metal (striker - bit) collision's sound; the 'kaching, kaching' sound is lesser compared to when drilling into concrete, because striker hits the bit much softer and being absorbed by the wood's fiber.

Here is a diagram of L shaped rotary hammer. In this case, Makita HR4000C. Look at the piston and cylinder and how similar to typical engine.



Here is my new 'family' picture.

Just found another rotary hammer's review. The model in this clip is Makita HR2811F, which is same as HR2810, but with shock absover and worklight LED. Unfortunately,this model is not available in Malaysia. Yeah, the few extra features also make it more expensive and not competitive in our market. I realized that the rotary hammer looks 'SMALL' in western people's hand.



Here we can see how the rotary hmmer with 'hammer only' mode being used for demolition and even 8 year's old kid also can handle it... mmm... I am thinking to train my 10 and 11 years old sons to do the drilling for me heh eh he.


Here is another review for Bosch RH328VC which is one of the GBH3-28 series.

The only thing stopping me from drilling more is the cleaning up. While looking for vacuum cleaner, found this ..

Yes bro. I know which shop you are talking abt. Was there during weekend. They are selling HR2470 for RM550. Warranty half year only.
Reason they don't stock is because they mostly do repairs/servicing.

But I want to know if it will do the job (drill holes on concrete). Any owners of 2470 can advise?

Thanks.

Yes, HR2470 or any 'big' professional grade rotary hammer. is very capable to bring concrete house down to dust!!. Use the it's 'power' wisely for peace and harmony.

Maybe 1/2 is to exaggerate, about 1/3 more like it. My contractor plaster wrong, using normal cement. And only use the dye on the final surface. He should mix it with the dye i brought when plaster. So i tear down the plastering. But guess it just too easy, i took down part of the concrete too leaving the rebar

I learn tearing down portion of concrete also need some skill and art. Better drill the area you don't want, than rotary it down. Is much easier and cleaner.

Great tip. Thank you. The holes make the concrete weaker and you also have the points where you can start the chiselling/demotion.

Waa.. your contractor seem to be had a hard time, working with the rotary hammer's owner like you. heh eh he he... Now, you can show them who is the MASTER.

If i move another house, think i will have most of the tools to build new house

ha hah ah ah .. ... By that time, most probably you are already listed in home renovation contractor association's BLACKLIST...

Max abt 10mm diameter? I want to drill 6-8 mm only.

ah yo 10mm only ah...

the makita 2470 can sap sap sui settle it la...

it can support up to 24mm

u should check out google for more info or a few pages back... the spec of 2470 has been shared/discuss before..

http://www.makita.com/en-us/Assets/Output/...4A947_79193.pdf

Yup... HR2470 drills 10mm into concrete just like child play, or like cutting butter with hot knife.. If you buy HR2470, most probably you will also get Makita brand 5 pieces masonry drill bits. 6, 6.5, 8, 10 and 12 mm.
