Watch a manual hole-punch setup built for spiral notebooks. We jog and square the stacks, set side guides and a 3–4 mm depth stop, verify 4:1 pitch with a gauge, then run test sheets to dial in registration. Each lift is clamped and punched, chips are cleared after every stroke, and holes are inspected for no burrs and even spacing. The result: smooth page flip and durable coil binding for small batches and prototypes—perfect for plastic-coil and light Wire-O jobs that demand accuracy.
