3 ring hole puncher for binder

Most listings show capacities of about 10 or 12 sheets. Some descriptions list a 10-sheet capacity generally, while others specify a 12-sheet capacity for 20 lb (standard) paper.

Several listings specify a 9/32" hole diameter as the standard punched size.

Many punchers include a built-in chip catcher or an easy-open/removable chip tray for straightforward disposal of paper scraps.

Several listings describe a rubber or non-skid base or pad that provides desktop stability during punching.

Some models feature adjustable or semi-adjustable punch heads that let you select 2-hole or 3-hole configurations. Availability varies by model, so check the product description to confirm this capability.

Warranty terms vary and include 30-day limited, 1-year limited, lifetime limited warranties, and some listings that show no applicable warranty.

Many customers report that paper alignment and emptying the chip tray are easy. A few users noted initial setup confusion caused by packaging or shipping locks, which is typically resolved once those are removed.
