    Default Cutting fibre cement with 40T circular saw blade

    I have to rip a length of JH Linea weatherboard - can I do it with a 184mm 40T narrow kerf blade circular saw blade?
    I'd really prefer not to buy a new blade for this one off job 😊.

    Thanks,
    Jonty

    You could but it will be shagged when you are finished. You can get a diamond blade for your grinder for $10 ad run that long a straight piece of timber.

    Cool. I have a diamond blade for the grinder, so could do that. The length I have to rip is only about 700mm. ��

    if it needs to be straight, I'd just circular saw it, and buy a new blade sometime - 700mm will blunt it a bit but not completely destroy it - one length of board is worth more than a blade by quite a bit

    Yes ... a real healthy advise.
    You could also use an ax.

    I'm @@@@ with grinders - some are talented and can do a perfectly straight line - one of the little wet saws would be golden

    I bought one of these for my circular saw. Cut a house load of linea board with it. still sharp. only thing to use. Probably a waste of you only have700mm but if you have to do more in the future its worth it.

    And wear a mask, goggles and gloves. The dust is not asbestos, but dangerous even so. No dusts are meant to be inside your lungs! BTW - score & snap still works and the edge can be squared off with a piece of course sanding wheel. eg: https://www.bunnings.com.au/haron-sc...knife_p5761150
