Thread: Can I use a disc grinder as a cut off tool?

  1. #1

    Can I use a disc grinder as a cut off tool?

    I got this one recently: "Can I use a disc grinder as a cut off tool?"

    My first thought was - of course it can, but what are you trying to cut and why would you use a disc grinder to cut with?

    I wrote back to ask what they were trying to cut, but since I'm not a woodworker or heavy tool user I never know if there's some inside jargon going on in these questions.

    Does "cut off tool" mean anything besides, say, a SAW?

    Is there enough in this question to answer reasonably?

    Thanks guys.

    I use my right angle grinder as a metal cut off tool all the time, if thats what they want. Just change out the grinding disk for a metal cut off blade. They can be scary though,,, ,,,, they turn real fast. Just use proper precautions.

    Cool! Thanks Don - I didn't realize it could be that easy...

    Do you have recommendations for cut off blade brands?

    I second that. I bought a cheap Harbor Freight RA grinder just for grinding and cut off use.
    God grant me the senility to forget the people I never liked anyway,
    the good fortune to run into the ones I do,
    and the eyesight to tell the difference.

    I don't see any answer to what material is involved - an angle grinder with an abrasive cut-off wheel can cut a lot of materials. The one it's probably least suited for is wood. Depending on the wood you might end up with a workshop full of smoke. In any case the cut will wander a lot more in wood than it would in metal or PVC, for example.

    For you folks with air, I have found that I go for this $20 little jewel more than I ever though I would have. It even cut through the 1/8" steel on the lumber rack standards like it was butter. Best $20 I've spent in a long while.

    I don't bring home a lot from Harbor Freight but sometimes........

    It says it consumes 6 CFM, so what does you pancake compressor produce?

    I use the 4" angle grinders for cut off too, there are a LOT of different cut off discs out there, from normal mild steel, Aluminum, Stainless Steel etc.

    Two hands, leather gloves, the guard in place, safety glasses, a full face shield and some hearing protection are in order. Add to that, when cutting steel, they throw a ton of sparks.



    I saw a guy in a body shop cut his hand off at the wrist, he was too lazy to use a wrench to replace the grinding disc, he would cradle the grinder in on hand, against his body, and then take the disc off with the other hand, well somehow, he bumped the on switch....... Yeah, he did not unplug it either

    had to learn how to write with his left hand, and drive, do up his jeans, etc. etc.

    They are a VERY useful tool, but you got to handle them with respect.
