I’ve tried punching 100# cardstock laminated with 10-mil. laminating pouch, I have found that the Cinch can easily punch right through it with no issues. As for punching a sheet of 100# cardstock that is laminated with a 10-mil. I have punched 20 sheets of the 32# papers, but it does require much force to push down on the handle, which can eventually break any dies if that much force is exerted.

Because I use 32# text weight which is thicker than the 20#, the maximum amount of sheets I punch at a time is 15 sheets. The typical copy paper is usually 20# text weight. The instructions on the Cinch cautions to not exceed 20 sheets of lightweight paper in a single punch. Yeah, I’m the type of efficiency-conscious nerd who actually have timed myself punching inserts. When using the Cinch, I can punch within 5-minutes a 1.25” thick stack of sheets. Other much smaller brands of 6-holes puncher that I have used in the past would end up breaking after a month punching all the inserts that my customers have ordered. To date, I have punched around one million sheets of planner inserts using the Cinch. But for office use, the Cinch is a work horse that has made the process of hole-punching more efficient. That leads to the next point:Ģ) The Cinch is a Heavy-Duty machine! Okay, so it’s not as heavy-duty as the industrial machines that drill holes into reams of papers in a single pass. So then why am I not rooting for the Planner Punch Board that was designed just for planner hole punches? Because unlike the Cinch, the Planner Punch Board cannot handle punching many sheets of papers at a time.
