Trying to cut circles in 2mm chipboard, and I'm running out of ideas.
Hey folks.
I'm doing some boxmaking and running into trouble with cutting circular holes. In my ideal build, I have a number of ~20mm (~3/4 in) holes. Unfortunately, it seems like the 2mm chipboard is too thick for traditional circle punchers. On the recommendation of another hobbyist, I picked up a hammer-driven punch traditionally used in leathermaking, but the tool doesn't seem to be a good fit for the job.
Has anyone tackled this before? I'm thinking about picking up a hole saw drill bit, but I'm worried I'll just tear the chipboard to shreds.
Would love to hear your ideas.
