I assume there pretty pricey!

I know the subject of riveting has been covered on other threads but I purchased this small kit mainly for the pointed punch and found it works fine along with a drill to remove existing rivets and a hammer to punch home the rivets. I was hoping to use the jaws of a bench drill chuck to hold the punch and to drive home the rivet but it just did not work. So judicious use of the punch & hammer did the trick for me at minimal cost.

That's right it will not work using the cupped die-it has to be a flat surface. I only used the punch and placed the article on a hard flat & protected surface and it worked fine but it takes a fair blow to secure the rivet.
