Frequently asked questions

What is the difference between the Diamond 6 and the Diamond 7?

The Diamond 7 rounds 2-3/4 inches, or about 700 sheets of 20 lb paper, and has a detachable press bar. The Diamond 6 rounds 2-3/8 inches, or about 600 sheets, and does not. The Diamond 7 runs a 200 W motor, the Diamond 6 a 100 W motor.

Which die is included?

One 1/4 inch die ships with the machine. Additional profiles are 1/8, 3/8, straight and half-moon, with 1/2 inch and 5/8 inch available as special order.

Can one machine cut different corner radii?

Yes. The dies are interchangeable, with a patented upper die and a micro-adjustable lower die. Changing profile means changing the die, not the machine.

Does it run on a foot pedal or by hand?

Both. A switch changes between automatic foot pedal operation and manual hand operation.

For lower volume, look at the Akiles Diamond 5. For occasional jobs, the Diamond 1 manual corner rounder needs no power. Most shops trim stacks on a guillotine paper cutter before they round the corners. See every Akiles machine we carry, and our binding and pressroom supplies.
