Hole puncher Centra HP30 black — metal construction, up to 30 sheets capacity

Centra HP30 black is a metal hole puncher engineered to create two clean, uniform holes in standard office paper. The device has a robust metal construction and a precision cutting mechanism that enables punching up to 30 sheets at a time. A removable waste tray collects paper chads for convenient disposal, and the slim black finish integrates unobtrusively into office, classroom, or home workspaces.

Advantages

The durable metal body of the Centra HP30 provides stability during repeated use and reduces flexing when punching thicker stacks. Its precision cutting heads deliver consistently round, burr-free holes to improve document presentation and filing. The integrated paper chad tray prevents desktop mess and is easy to empty. A simple alignment guide on the base helps position paper accurately for uniform hole placement.

Suitable for

• Office environments for routine document preparation and filing
• Schools and educational facilities for class handouts and student work
• Home offices and personal paperwork organization
• Light administrative departments with moderate daily punching needs

Key specifications

• Construction: metal body for increased rigidity and service life
• Capacity: up to 30 sheets of standard 80 g/m² office paper per punch
• Hole pattern: two holes with standard spacing for ring binders
• Cutting mechanism: precision steel cutting heads for clean holes

How to use

Align the stack of paper against the built-in guide on the punch base to achieve consistent hole placement. Press the lever evenly down until the punch heads penetrate the full stack. Release the lever and remove the paper. Periodically open and empty the removable chad tray to avoid buildup. For best results, avoid exceeding the recommended sheet capacity and feed only flat, uncreased paper.

Usage recommendations

Use the Centra HP30 on a stable, flat surface. When punching near the maximum capacity, press the lever firmly and evenly to ensure all sheets are cut cleanly. Inspect cutting heads periodically; if holes become ragged, clean any accumulated paper residue and, if necessary, replace the punch or seek professional servicing. Store in a dry place to prevent corrosion of metal components.
