The BetterBind COIL-IT Coil Binding Machine offers manual punching and electric coil inserting in one compact unit. Featuring a rugged steel construction, the COIL-IT punches a 4:1 round hole pattern (with 46 disengage-able pins) for easy coil insertion. The COIL-IT punches up to 20 sheets of 20lb bond paper (or equivalent) at a time, and allows you to electrically 'spin insert' your plastic coils through these same holes up to 12 '' in length and up to 7/8" (or approximately 190 sheets in thickness). Larger coil up to 2'' in diameter will need to be inserted by hand. The COIL-IT also includes a foot-pedal to start and stop the coil spinner. The BetterBind COIL-IT is the perfect solution for offices, schools, and libraries! Includes a pair of coil crimping pliers
