These are a 10 dollar must-have set of punches for any/all gasket work.
The set I got 10 yrs ago had a couple of larger sizes up to one inch.
In five minutes I knocked out a pair of the four hole petcock seals from the lid of a 5gal poly pail with these punches. Much improved over soft rubber orig. No leak and haven't worn out in many years. (edited)
