    Cutting Basalt Rock

    Anyone know what type of disc I need for my 230mm grinder to cut some strips in basalt rock? Will a concrete disc do it? Segmented?

    While digging the plumbing trenches I've come across a few and the rock breaker takes forever. Just want to cut some lines to aid the breaker and not have to battle the entire rock.

    The old man spent a few days on the en of the jackhammer in central getting through the schist. Don't think he used a grinder but will ask

    Use a wet saw, I have cut every type of rock with them from Igneous granites, basalts, and Metamorphic rocks as well as sedimentary. It cuts them all as I had to cut hundreds of rocks during my Geology studies.

    Yeah What Stickbow said. See if you can get a petrol powered one from hirepool, Basalt will kill a grinder sized diamond wheel real quick.

    Petrol powered with a hose attached. The water makes all the difference.

    100mm nail hole in the lid of a soft drink bottle filled with water and get some bystander to keep squirting it at the cutting area - segmented diamond blades are fairly cheap on tardme and children are just unemployed labourers y'know

    Fibre concrete cutting blades erode extremely quickly and are as much good as a chocolate teapot


    Best tool is a powersaw Husky or Stihl with hose attachment and a 16" blade but the version above is for tightwads doing a small area

    Hitachi heavy breakers and the new Hilti ones are the best bang per kg IMO

    Depending what is around powergel or nonex stuff if it is closer to buildings walls etc.Let face it stuff that goes bang in a controlled manner is way more fun than a boring concrete wet saw

    You don't need a ticket for nonex, and it can be sent through the post,I have used it often and you will get the best results from some one who knows what they are doing each man to his trade and all that, it is reasonably straight forward

    a mate was in aussie years ago and he saw a plumber drill holes in the rock around a house put explosives in, cover with sacks and blast. The sacks held in the flyrock and he just shoveled the loose stuff out and laid his pipes
