There are a few larger pieces of shale that needs to be broken through. I also have a few old posts cemented it the ground, which I want to break up. With this in mind, do you guys any suggestions of a jackhammer I could buy?

I did this when I had to break up a brick front fence. Cost about $50 for the day. Much easier than using a sledge. Re: Jackhammer advice 5Feb 21, 2015 1:25 pm I have a GMC machine. 2000W. Looks like a super overgrown power drill. Sure, it works but it is very slow, noisy and the vibration is terrible. I have hired a Kanga in the past and it was far better for the bigger jobs, you could use it standing up and the sheer weight of the machine made it far more effective and easier on your body. Re: Jackhammer advice 6Feb 21, 2015 8:17 pm You have to work out whether you can knock this over in a day ( probably hire is best ) or whether this is going to be over a couple of weekends ( buy one ). Anything less than a decent sized electric jackhammer like one of the bigger Makitas is going to cost $900+ but will last a long time. The cheaper stuff won't. As with anything in the building industry you get what you pay for. Stewie Re: Jackhammer advice 8Feb 21, 2015 9:57 pm The bigger Makitas and Bosch jackhammers are closer to the real pneumatic ones that run off a compressor. Then there are those that other companies call jackhammers but they are really only a bigger version of an electric drill and OK for stripping render off a wall, taking up floor tiles etc. Stewie Re: Jackhammer advice 10Feb 22, 2015 7:31 am It will do the job. I used to have Bosch electric breaker and yes it's a great tool but there is no point buying best tool if you are only going to use it once or sporadically. It will come with home use warranty with return option if it does not perform as it should.

The closest match to these in the bunnings models "full boar" is the $400 machine, not the $300 one. Don't waste your time with the $300 one, I've got the same size machine in the Kanga brand and it's got nothing on my bigger one and will be under done for what you want. I've used the Full boar $400 one and also the "Good" brands and they do run smoother and seem to break better, but for what you want the $400 Bunnings one should do the job Re: Jackhammer advice 12Feb 22, 2015 10:29 pm If you are only going to use it for 1 job then even if it takes you 3 days (3 x $150) you'll save $150-$200 over a Bunnings one and the job would be easier with a hire unit. Re: Jackhammer advice 13Feb 26, 2015 7:14 pm Just make sure you have the strength to actually lift and control the jack hammer over a period of time. My neighbour board a $450 jack hammer at Bunnings. (I cant remember which one but I think it was the largest one they sold). I borrowed this jack hammer and found that although it easily cut through rock, I could not lift it out of the hole that the bit had made. In addition, in order to get the jack hammer started one needed to lift the bit of the jack hammer off the ground some distance and drop it. (This jack hammer was mounted on a spring and one needed to get the spring to resonate for the jack hammer to work effectively). I found lifting and dropping the jack hammer very hard on my back. I eventually gave up on using it.
