These guys specifically say it works in cast iron.
I gotta say I'm leery too. But the grip nail stuff clearly makes the claim.

well let em try that with their own chipmaster
my lathe already has the holes too, so it is a no brainer to just use standard drive screws. I do wish I could find brass or bronze ones though.
More than leery, how would it be possible? If the material is 1/4" steel, how could anything drill it's own hole?
I'd say just read their literature...

But like I already said, I'm leery. Marketing types love wild claims cuz there is always a fool willing to part with his money.
I'm with @TorontoBuilder, drill a hole and use a rivet nail.
Your wish is my command! Maybe not really brass but they will look like it.

The Gripnail system uses what is essentially a single shot air hammer to drive the pin into the material. There is no drilling, just impact to force the pin in and then the geometry of the pin forces the material to compress around the pin to hold it in place. Looks kinda slick.

yeah, I know. I had aircraft spruce open from looking at the hobby air systems

There is nothing quite as fun or convincing as empirical evidence you collect yourself. Video please..
I'm with @TorontoBuilder! But I don't really care about the video. I just wanna know what happens......
No video, Gripnail into well-seasoned cast iron failed miserably. A few sparks, then the rivet snapped in half. We normally use them into valves made of ASTM A126 Grade B, my test piece was a chunk of mystery metal that used to be the weight in a decades-old floor lamp. A126 is tempered after casting, probably a lot softer than the lamp weight.
