You can use this paper hole punch to create clean 1/8 inch round holes. It is recommended that the thickness of the material should not exceed: 0.04 in / 1.0 mm for hard card, 0.06 in / 1.5 mm for paper, and 0.06 in / 1.5 mm for PVC. Up to 15–20 sheets of A4 paper can be punched at one time. This heavy-duty hole punch features a super long reach with a paper input depth of up to 53 mm, allowing it to punch holes in business cards or 6-inch photos. Paper feed depth is 53 mm (measured from the center of the hole to the edge of the paper). Unlike traditional hole punches that only punch within 10 mm of the edge, this design offers greater flexibility. The hole punch is constructed from zinc alloy with a stamped structure and chrome-plated surface, providing a bright, attractive finish and refined appearance. The punching blades are heat-treated and hardened for increased durability, ensuring long-term, burr-free performance. It includes a built-in spring and waste collection slot to contain paper scraps, helping keep your workspace clean and preventing mess on your desk or floor.
