We have carried punch sets like this in the past until their costs became prohibitive, and have been looking for sets which provide a very good value ever since. Here they are. The two sets complement one another.
The small boxed set of 6 punches, which screw into a steel handle, are sized in very small increments from 5 to 8mm (3/16" to 3/8"). The set of 9 large punches is sized 5mm to 32mm (3/16" to 1-1/4"). These also screw into a steel handle, and you can use the optional supplied spring-loaded auto-centering locater if you are cutting multiple disks on a grid, or when cutting concentric holes (as when making a washer).
