ONYX HD6500
The HD6500 is a 14-inch (365 mm) open-ended spiral, comb, wire and coil punching machine that has interchangeable dies. The HD6500 punches 30-40 sheets of 20lb copy paper depending on punch pattern. Dies are removed by removing 2 bolts from behind the chip drawer. A great choice for those who do not require changing of the hole pattern frequently.
