Has anyone used one of these. Looks like a nice tool.

Sort of a Greenly style punch like electricians use, not really that useful for our type of work. You have to drill a hole first for a bolt or stud to pull the punch & die together. ~ John Buchtenkirch

I have an old set of these.
I use a shop press for them, after punching the lead hole. I bond in the line-up pin, oil the part, and push. Some setup for the lower die is helpful.

For about the same outlay$$ you could get 10-15 hole saws that work on both flat and curved surfaces. Hole saws also work on thick and thin materials and wood and plastic.
If you are not sure you need them you likely don't.

Default Punch use

My plan was to use these for making lightning holes on a car door. The punch seems like an easier route than cutting out the inner door structure to put it in the press. They sort of imply that you can do dimpling as well , with the right mix-and-match of dies. Making dimple dies wouldn't be hard either. But, I don't want to get this if the seals go out in a week. It doesn't sound like anyone has used one, so I think I will get it and report how it works.

When installing holes in firewall for steering column for example they are a godsend . Many other as well Hole saws are not consistent also as they tend to wander . Also by the time you wear out the hole saw , this punch is still hanging in there . Save the holesaw for wood

I have a drawer full of Greenlee punches that I have been using for decades for automotive, aircraft, and electronics. Can't imagine being without them (well, I can but it's not pretty) and worth every penny.

There are over 200 Greenlee chassis punches on ebay right now.
I'm sure I'm not the only one that uses drill rod as the center on hole saws. A good tight hole made with a stub drill makes for a more accurately sized bore cutting down on saw rim wander and reaming by the pilot drill.

I can get good accuracy with hole saw diameters by using a hard pilot (non-cutting drill stem okay), just the right speed (VSR), and a good cutting lube.

Dont waste your time, Holes saw are the way to go, You can cut 3 holes to 1 compared to that style punch, maybe more..
But! if it flares at the same time different story..
