    Cutting Copper With an Angle Grinder

    I've got a big job tomorrow where I've got to cut out 1 1/2" in some close quarters and propress in some new valves. I hate using a sawzall it leaves a rough edge and causes too much vibration. I want to use my angle grinder with cut off blades. I think it will work out very well but I was wondering if anyone else has tried doing this?

    The only time I have used a cut-off wheel is for demo. It does cut, but it does leave a burr on the pipe.

    Done it before and will again. Only worry was/is the fillings but if its b4 the suction drier I think it'll be ok.

    I would prolly never do it on a refrigeration system. Unless I had a filter downstream.

    On a hot water loop, it shouldn’t matter.

    A cutoff wheel seems to produce more debris than a saw. Plus you’ll have to clean the cut edges before putting in a propress fitting, etc.

    Okay for water this is the way to go, no vibration then you have a grinder to bevel the edges really nice and fast. But 71Chops made a very good point. There were way too much fine particles in the line afterward. I would never do this on refrigeration. I am going to buy that chain cutter that crazzycajun posted though.
