Routing plaster - does it blunt the blade ?

    So, I wanted to route out a channel in some plaster to bed speaker cables which are, at the moment, sitting in surface mounted conduit. Rather than chisel out such a narrow section, I was thinking of using a router with extraction attached. Any major reasons why this isn't a workable idea ?

    I imagine that the blade will be toast afterwards but that it would work
    I am guessing that you're taking about 16 feet of routing?

    assuming you mean a woodworking router and not some other sort

    very dangerous in my opinion as the machine is difficult to control and held at the most
    awkward and most dangerous angle
    in wood your restricted to half the shaft depth off plunge so would need several passes
    and when the cutter finds something it doesnt like it will kick the machine violently
    and iff the cutter breaks you have a heavy metal missile spinning at 20000 rpm

    I bought a useless bolt on to a drill tool that was sort of a router/milling thing
    It made a ton of dust.

    would an angle grinder/disc cutter used carefully work? Dust would be an issue again

    Fair comments. Although I would say the router I have operates at ridiculously low RPM. The main benefit would be containing all the dust as no matter how careful I am with a cold chisel a lot of dust collects on surfaces

    For the depth of the channel ? Not really.

    I just need it to be about 20mm deep,enough to house the conduit that is surface mounted at the moment.

    get some cheapo router cutters from toolstation -I bought a couple when rebating a liner which had nails in it.

    the cutters were the rubbish silverline brand but they cut pretty well (smallest sliver of TCT on them).

    A router isnt ideal for cutting a masonry material it wont last very long, but I guess itll cut neatly while it does!

    I wouldnt try plunging though -best to drill a start hole.
