That depends. I suppose a adapter could be made for the ones built

Thanks Wayne. I had a look at the Milwaukee range and I see what you
mean. I've only ever seen the Rotabroach kind for sale in England, and
I'd quite like to be able to use the Rotabroach cutters, so I was
wondering if an adaptor was available? As you say, it might be possible
to make one.

Presumably the kind of magnetic drilling machine which is built with a
Jacobs chuck spins faster, so drilling with twist drills on the
Rotabroach kind of machine might take a while? I don't mind that too
much, though - most of the time my drill press is set on the lowest
speed because the belts are so fiddly to change.


Again it depends on the machine. Mine has a 3/4" chuck single speed
version that goes 350 rpm max. But they also make two speed versions.
