10kg Demolition hammer

[aidank]

Im in the market for a concrete demolition hammer ~10kg weight.

Initial thoughts were to purchase a rotary demolition hammer however I was doing my research, it appears the impact energy is much higher from a dedicated hammer machine rather than from a rotary demolition hammer.

doubt I will buy a hilti $$$$$$$$ even though I know they are the best

I dont have enough experience using rotary demolition hammers and single purpose demoltion hammers to confirm the theory. Anyone able to shed any light

From the hilti website
Hilti 700 Drill and Hammer Impact energy 7.9kg 11.5Joule
Hilti 800 Hammer 10.6kg 21Joule
Hilti TE1000 Hammer 12.5kg 26Joule

From the bosch website
Bosch GSH 11E Drill and Hammer 10.1kg 16 Joule
Bosch GSH 11 VC Hammer 11.4kg 23joule

I guess a X quantity of the motor power goes into twisting the drill and Y into breaking, so that when switch to breaking only mode that Y is all that the hammer can absorb, whereas if you start with a hammer only machine then 100% of the motor power is available for hammering.

Other than Hitachi Bosch Dewalt Makita, are there any other brands I should be considering, when I use it which will be once a month Ill be using it all day rather than 10mins every day. It appears there is the regular brands and then Titan, is there anything in between ?

I see that Milwaukee is not recommended!

for the cost (negligible), the big titan is an impressive tool and you have three years in which to wreck it and have a new one on the no quibble guarantee

It's 15kg and the vibration is terrible. If you are in the market for a 15kg tool the Erbauer is much better and well worth double the money.

10kg isnt much of a breaker, more a beefed up drill.

If there is absolutely no way i can hire in a micro and pecker then ill use the jcb one off a beaver pack. All the electric ones are just too crap I found, slow not heavy enough.


Breakers are really hard on the body hence always using a digger even for small jobs. I'd rather pay £120 for half day hire and get it done in 20 mins rather than hump a breaker about for an hour and half.

The problem with the cheap ones is the vibration. They don't even give you a vibration figure so must be bad. I've got a draper one and although It weighs very little it's good for digging out fence posts and walls. It's not something I would expect to last much more than a year though. I will be interested to see what you get and how you get on with it because l would like a proper one when my cheapo draper dies.

I think we’re missing the point guys. He’s after a 10kg breaker, probably for smaller work in areas you can’t get a machine to or maybe for vertical work where you have to hold it up.
I’ve got the dewalt breaker, it takes SDS max bits and I thought was a good balance between performance and price. I’d have bought the Bosch one if there was a decent deal on as they seem almost identical, so it really depends on what deal you can get at the time.
The Hilti stuff is great but new it’s fierce money and whilst there’s lots about 2nd hand, it’s almost the cost of my new dewalt hence I bought it.

Yeah,I got the draper and agree with you. Trouble is next step up is £800 plus seems like

Anyone ever bought a reconned model, you can get a bosch gsh11e for ~£250

Avoid the titan or any other DIY branded tool.
They are utter crap, vibration levels are far too high.
Avoid the Milwaukee or the kango branded ones as they are also dogshit.
Beside the joules or blows of the bit of kit, you need to look at the m/S2 levels you can pop these into one of the calculators and it will give you the 2.5m/s2 limit for when you should start to look at alternatives and the 5m/S2 limit where you should stop using that bit of kit. These times are for a 24hour period.

The hilti is the only one that is able to see 8 hours trigger time for a day

I you have workers and at some point in the future they claim for vwf they chase all the employer's back through the history for the compensation and with some claims being 40k how cheap does that titan breaker look now

 

[Jimoz]

In 20 years would an employee seriously be able to prove they used a titan breaker for you on a job for 6 months?

More a case of prove they didnt id say nowadays. Hence why we have all those lovely record sheets for it all.

Same with the claims for silicosis/asbestos they look at chasing payments throughout the work history rather than a "last person to touch it" scenario

Dedicated breaker is always better than breaker/drill more so because they tend to be slightly smaller and lighter for the same impact force. Usually more reliable as well. Lot of builders round me have Makita sds max breakers (think 7kg) seem to last well and good to use from what little I've borrowed one and as gunners says can be used in the air. If i can't get micro and pecker in borrowed makita aint man enough its compressor and jack hammer for me so can't comment on bigger electric stuff

 

[aidank]

I am now the proud owner of a second hand Makita hr5001C 10kg SDS Max demolition hammer

I guess I need to give it a service, even though it hasn't seena a lot of use, is it just regular O rings that are used in the hammer mechanism of demolition hammers or are they a special type ?

How about grease type for such a tool for the conrod, special grease or a regular grease

 

[Russell]

Ive just bought a small, medium and large makita so it will be interesting to see how they compare to what I currently have.

I bought the 30kg hm1812 last month.

Remember to go on Makita website, sign up and register the tools to get your 3 year warranty

I bought my three at auction and all are used.

was gonna ask if you'd had yer numbers come up

I've been using my Makita hm1202c today and it seams to be good and I'm impressed. It's definitely got a lot more power than my draper and is not much heavier. I think the draper must be measured with Chinese joules because apparently it's 25 j and Makita is 21.9j and Makita is considerably more powerful.

Chinese lumens is the other one!
