Comfortable Three-Hole Punching

The Master MP40 desktop hole puncher handles up to 30 sheets per stroke. A soft-touch gel padded handle reduces hand fatigue during repetitive tasks. An adjustable ruled paper centering guide keeps alignment accurate for standard three-ring binders. Durable steel construction supports daily office use.

Low-Effort Operation

The oversized handle requires minimal force to punch through 30 sheets. Non-skid feet prevent the unit from sliding during each press. A large-capacity chip pan collects waste so emptying is less frequent. The handle locks down for compact storage and safety when not in use.

Practical Accessories Included

The built-in chip pan eliminates loose paper confetti on the desk. The padded handle and lock-down mechanism change the feel from a basic lever to a more ergonomic tool. The adjustable guide removes guesswork when positioning pages for 9/32-inch holes. These features suit high-volume filing tasks.

Questions about this item

How do I set up the adjustable ruled paper centering guide so the three holes line up with a standard binder?

Slide the guide until the ruler marks match your paper size, then lock it down; the punch is pre-set for standard three-ring spacing, so the holes will align automatically.

Which part of the Master MP40 will need emptying or cleaning after repeated use?

The large-capacity paper chip pan collects the punched-out discs; pull it out and empty it when it fills up to keep the mechanism running smoothly.

What happens if I try to punch more than 30 sheets at once on the MP40?

The punch is rated for 30 sheets maximum; exceeding that can jam the steel mechanism or bend the punch pins, so split larger stacks into multiple passes.
