If you have ever tried to use a small desktop 3-hole punch to handle hundreds or thousands of pages you know how frustrating it can be. Those little units are fine for small occasional jobs but for larger tasks you really need something more substantial. These Swingline heavy duty three hole punches are just that. Made from stronger materials and able to punch more sheets at a time they are the perfect solution for larger jobs and frequent use. Compare models based on punching capacity, number of punching heads and their construction.
