Demolition hammers

[Driller]

I need a demolition hammer and have been looking at the Makita HR4511C but can't try before I buy. Anybody got one of these or tried one. Any good?

I hired one a while back. It did indeed knock down the fireplace I needed to knock down.

I though this thread would have been about Spurs' last two games with West Ham

There's no need for that. Tell Big Ern I'll have his money by the end of the week. 'Onest.

I wouldnt really class this as a demolition hammer as it has no rotary stop function on it. I have one though and as a regular hammer dril it is superb, but i do find my self getting out my smaller makita sds drill as the largest holes I drill are usually 28mm. Any larger and the core bits come out

I've got this one. Not let me down yet.

i bought a no make one from screwfix . its had a hard life and never let me down. it is a bit agricultural but has roto stop. cost about £50 and will go through anything. if i used one every day i might buy a really good one but i do not have a use for one anymore

I have the previous version of this:

For diy use its fine, had a lot of abuse especially on Chisel action.

Do you specifically need SDS Max

Doesn't state if you want 240v or 110v

Or makita unit much cheaper:

Thanks for the replies everyone.

HI, when you say "no rotary stop" do you mean that if the drill bits snags then there is nothing to stop the whole body spinning around and twisting my arms off? I specifically wanted this feature and thought that the "torque limiter" feature was the same thing.

If this isn't the same thing what would you recommend in this class that has this feature?

i think roto stop is if you just want to use it as a chisel / hammer , so the bit does not spin around. taking down a wall for instance , you would set it to roto stop and then chisel out the mortar.

In this context that's called a clutch.

Rotary stop means you disable the drilling (rotation), leaving just hammer.

if you can get 110v (or buy a 110 transformer), you'd get a kango off ebay, or a hilti one

Thanks for that. It would appear that this model has something called a:

"Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the bit will stop turning"

I presume this is the same thing.

Also I think you jumped the gun a bit HomeImprovements because apparently it has a Hammer Only setting which means it can in fact do demolition hence "rotary demolition hammer".

If it's just for use as a breaker you can buy titan and other crappy makes for £30-40, we use them at work for drilling also. Whilst they aren't fantastic they do the job and its better than half a grand on a top notch piece of kit if it's only to be used a couple of times?

It's not just for breaking, I left off the rotary in the title. I may go for a slightly less OTT version though, SDS+ rather than max.
