Hi
One thing to remember for punch health is to keep them lubricated.
This is especially true for aluminum. It tends to stick to surfaces.
It can cause the punch to skew and break. A light lub on the
blade works best while the threads should use a grease.
Cleaning the threads will also help to keep chips from getting
into the threads.

It happens that I am also active at the diyaudio
forum. I had bad
experience
with those punchs and I started a thread there,

I can't vouch for them, I just noted the coupon and remembered the
tiie-in. I've got a set of Greenlees that's perhaps 40 years old and
works just fine.
Maybe these'd be okay with aluminum or very mild steel. Sigh.
Probably the same Chinese boron steel that makes bolts snap off if
you look at 'em sideways.
