Electric breaker any good for posts holes?

[scbk]

Has anyone had much success using a circa 15kg electric breaker/demolition hammer for digging post holes in very stoney ground?

The sort of tool you see advertised in screfix/toolstation ie https://www.toolstation.com/draper-expert-1700w-185kg-breaker/p21125

 

Either for trying to break up large rocks, or at the very least dislodge them enough to be removed with shuv-holers

 

 

I have in the past used a 30kg hydraulic breaker (regrettably I sold it) and it was semi-useful. The problem was if it got stuck in the soil, it was an absolute pig to pull out due to the weight of it, and being well buried. (I work on my own)

What you want is the air powered spade thing that Lidl sometimes do. Available on eBay if they don’t have it.

 

need a compressor too but it’s what you need. A breaker is too heavy and it’s hard to find a long point. I’ve tried it but the air spade thing is way better.

I use the bosch 16 kg 25mm light works of generator or mains, have a selection of points chisels and a spade with a good pair of hole spades covers most jobs

I use a Makita breaker

bit heavy and not cheap now but gets job do and got a 900mm long chisel for it.

I remember seeing that in the lidl leaflet at the time, didn't think it would be heavy enough to break rock/concrete etc?

It's surprisingly good. Easily as much power as a 10kg breaker (probably a little more) but in a very lightweight format that you can handle like a spade. Really handy bit of kit, we use ours all the time on any footings that need a bit of hand digging. Goes through heavy clay beautifully- turns an hours hand digging into twenty minutes and no effort.

 

We use a 25l /2.5HP compressor and it makes it work hard.. I wouldn't want to use it on a 1.5HP compressor, and I'm hoping the petrol compressor will keep up with it.

This is the same thing but more expensive

I use a large electric breaker but that looks like a useful bit of kit....not too costly either.

 

It's worth knowing that the Chinese electric breakers do not like the wet or even damp conditions, I keep a plastic sack over mine when out......if moisture gets to the brushes they can evaporate spectacularly, cheers.

Worth looking at the petrol breaker/drills, they use the sds max system. You obviously get what you pay for but handy bit of kit nonetheless.

I've got the same drill. Handy for certain things, but I found the breaker force pathetic compared to a similar electric machine, and not a patch on the air spade thingy. Also very heavy to use.
