Corded concrete breaker/jack hammer or one of them hydraulic breaker packs?

[Martin Hocking]

I’ve done a fair bit of breaking with the titan type one mentioned above. And it’s good enough for breaking up a 4 inch slab without too much bother. But I would mention one caveat with it.

The bearing housing for the back end of the motor is plastic and if your going to be on it for hours on end be aware of the motor getting too hot, if the thing starts to make a funny noise, stop straight away and let it cool down. I killed our last long suffering one at work when a job needed to be done at all costs.

They are very affordable for what they are and when I took it apart the switch is replaceable and there was tons of meat on the brushes left after all the abuse we have it.

To be honest though I’d listen to @pete the man eats concrete for breakfast and gets paid to do it!

A sthil saw is a very useful addition when breaking out concrete….cut crack lines and break away.

I'd hire a beaver and hydraulic breaker. Way better than any electric we've used.
Its maybe actually more cost effective to get a minidigger and pecker...

all you will do is get the tool stuck and wont get it out

Make sure you have at least two chisels to fit whatever you get. At least you stand a chance of getting the first bit back if you can work around it

Look after your hands. A lot of years ago I hired a girt big electric breaker to take down a surface air raid shelter, weighed about 40 to 50kG at a guess. if there is a chance of breaking through a void then make sure you have good footing as the drill takes a lot of stopping

I woke up the next morning with hands fixed as claws. I couldn't flex my fingers at all. I had to get back on with the breaker to get them loose

At 15kg you are trying to control 3/4 bag of cement

You youngsters! A proper bag of cement weighed 1cwt or 50Kg in new money. Of course, back then, that was a one man lift

Well it got used today, was initially impressed then disappointed, but that was me not knowing what I was doing ie it happily hammers solid concrete but anything wobbly/loose is a no go, and it did a damned fine job, found the slab had 1/4 inch rebar mesh in it, the jack hammer did cut through some of it, but bounced on the rest so I need some bolt croppers.
It would appear it likes a drop of oil as it leaks a bit from the chisel holder, blurb says this is normaL so keep on hammering.

Slight update, I had to buy a smaller breaker as using that big bugger sideways was almost mission impossible.
Have to say smaller machine is actually quite good, I might have been able to get away with just the one, but I have around 10 odd feet of 2 foot square concrete to break up and I rekcon the bigger machine will be the kiddy.

That looks identical to the Titan units - great value for the money, but you absolutely would not want to be using one all day every day.

Quite likely simply a rebadged item? On the other hand, some electrical tools I have seen - that appear identical on the outside - contain different quality internal parts.
