It is still going to be a lot of work going through material that
thick. (Hmm ... was it steel, or aluminum?) Steel will be stressing the
Greenlee punch nearly 1mm thick material. Aluminum you can probably do.

The capacity of a 1" slug-buster punch is 14ga (2.0mm) in steel. A 1"
slug-splitter is good up to 10ga (3.5mm) SS.

Good news. But he will still need a good solid vise to hold the
punch end while he turns the screw in the die end. What is the needed
torque for even 14 ga steel, let alone thicker stainless.

For that matter, how does it have greater capacity in stainless
steel (3.5mm) than in plain steel (2mm). (I presume we are talking
about mild steel.)

For that matter -- are those figures for turning the drive
screw, or for using a hydraulic puller?

I've never had a slug-buster (slug-splitter the same?) -- they
came out after I got my punches, but it would be nice to have that
feature.

Slug-busters and slug-splitters are different products. They both cut
the punched out slug in half so it doesn't get jammed around the draw
stud, and they look very similar. I'm not sure why the slug-splitters
will handle heavier material. Perhaps it's the material they're made
of. Slug-splitters are only for use with hydraulic or mechanical
pullers, not a wrench on the draw stud.

Slug-busters have been around for at least 25 years, slug-splitters
are a more recent introduction.
