The BINDpro Denali 12E electric operated, modular punching machine comes with an affordable price tag and provides the binding options needed for everyday tasks. This sturdy, all-metal machine can handle 30-55 sheets of 20lb paper, and using the same punch, you can switch from coil to a wire or comb binding project. While one die of your choice is standard with the unit, additional interchangeable die sets allow you to switch punch patterns within seconds, without additional tools. The high-quality precision die sets boast fully disengageable pins, allowing the use of any paper size without creating partly formed holes at the ends of each sheet. It includes an auto-reversing function and a lubrication filler port for ease of maintenance. The BINDpro Denali 12E is a stand-alone binding punch that can be complemented with a coil inserter, comb opener, and wire closer for a complete binding package.
