Hi, a quick bit of background: I've used Rotabroach magdrills loads of times at work, but always on thickish steel, RSJ's etc, maybe 16mm upwards roughly at the thinnest.
I was thinking of getting one myself, to make big bolt holes and pipe holes on my barge, but the steel is only 6-8 mm thick in general.
I downloaded the manual, and it just says, "performance of the magnet will get progressively weaker from 25mm steel downwards"
So my question is, how thin is too thin, for the magnet to hold safely? On a vertical surface. Anyone tried it, maybe even found out the hard way and broke a cutter..
Can the cutting bits even cope with such thin steel? If not it will be holesaws.
thanks in advance
edited to add, the more I think about it, the less likely it seems to be a good idea
