A few years ago I bought a package deal with 3 speed hammers and 1 factory because there was a kepplinger included. I used carbide endmills and copied some of the cuts without issue on the factory hammer. I think I still have a speed hammer or maybe the one I altered... I can try and dig it out if you need pics.
I did read that the weight should not go below a certain number for reliability but can’t recall the number. I think it was on the assra forum.
