This heavy-duty hole punch blows the competition out of the water in a few key areas. First, the three-hole punch features a whopping 160 sheet capacity. This makes it ideal for lawyers, insurance brokers, college professors and more! Many other high-capacity punches only offer a max capacity of 100 paper sheets. Next, the unit is completely adjustable. Users can easily change the punching configuration from three holes to two holes depending on their needs. Last, this unit contains all the features that come standard in any punch. Each Xtreme duty hole punch features an adjustable paper guide and a high capacity chip catching tray. Best of all, users can purchase replacement punch heads and discs to return their puncher to out-of-the-box condition! Why buy a whole new punch when you can swap out the punch heads? To help prevent the build-up of germs on the hole punch, each unit has an antimicrobial coating for communal use. If you plan to use your heavy-duty hole punch daily, this is a great option to consider! Agion® is a registered trademark of Sciessent®. For more information on Agion® Antimicrobial their website.
