The Rhino Tuff Binding Machine binds loose sheets into impressive looking documents with and can quickly punch 25 sheets at a time. The system’s self-lubricating dies keep us punching at maximum capacity, and overloading the punch isn’t a problem with the automatic jam-stopper which quickly reverses punching jams. Its large and powerful coil roller quickly zips the coil into place, while determining what size coil to use is simple with the built-in Document-sizer. For binding thicker books, the built-in Book-former aligns punched sheets for easier coiling, so even your biggest jobs will get done quickly and with wonderful quality!
