I started out using a tool I had to do 1/4" CRES rivets. No luck. With this tool you can quickly adjust the size and just as quickly set 1/4" CRES rivets and I'm certain smaller rivets as well. The nose adjustment was new to me but it worked flawlessly. No need to use a wrench to change the nosepiece, this one you just rotate to the size you are doing and go for it.
