The 10 Best Heavy Duty Staplers

For binder-thick stacks, the Bostitch 00540 is a bench-style lever stapler rated for up to 215 sheets. It loads from the rear and takes staples in several leg lengths, so it handles short memos too, and the frame is all metal. A seven-year limited warranty covers it, per the seller. It needs the right staple length for each stack, and jams and durability are hit or miss.

Rated for 160 sheets, the Swingline 39005 is the classic gray-and-black heavy-duty model from the best-known U.S. stapler maker. Swingline's heavy-duty staples come in several leg lengths, picked by stack height. An alignment guide helps place each staple, a door at the front lets you clear a jam without taking the head apart, and the base is all metal. It's solid, but it jams with ordinary staples, and some units stop working within months.

One staple size covers every stack from 2 to 130 sheets on the Bostitch EZ Squeeze 130, so there's no drawer of leg lengths to manage. A low-effort linkage needs a gentler push than a plain lever and runs quietly, which suits shared offices and libraries. It clinches the legs flat so stapled sets stack neatly, and it has a limited lifetime warranty. It only takes its own staples, and some units break.

Built for people who staple thick reports all day, the Swingline Optima 70 fastens anything from a couple of sheets to 70 with one staple size and less force than a standard lever, which helps sore wrists. To reload, you press a button and the magazine slides out the front. The stapling mechanism is metal, and a limited lifetime warranty covers it. It needs Swingline's own Optima staples, and it can jam over time.

From an established British maker, the Rapesco HD-100 handles up to 100 sheets at a low price, with a box of staples included. It loads from the front with a push button, has a locking paper guide, and pairs a shell made largely of recycled plastic with a metal chassis. The stated warranty runs 25 years. The catch is supply: U.S. shops rarely stock the long Rapesco staples it needs for thick stacks, and the stapler itself runs low.

The Bostitch Titan looks like an ordinary desk stapler, but it doubles the usual sheet count: standard staples handle up to 25 sheets, and the longer staples in the kit fasten up to 50. The metal body sits on a non-skid base, and the head opens flat for tacking papers to a corkboard. Part of each sale goes to cancer research. It suits a home office, not big jobs, and Bostitch offers a satisfaction guarantee but no stated warranty term.

When the paper can't come to the desk, the Rapid K1 goes to it: a chrome-plated steel plier stapler, still made in Sweden. Squeezed by hand, it fastens up to 50 sheets with high-capacity staples and also takes standard ones. An adjustable anvil switches it from clinching to pinning, handy for tags, bags and bulletin boards, and a five-year warranty covers it with Rapid staples. Thick stacks take a strong grip, and back loading is slow.

Print rooms that staple booklets through the fold are the audience for the Novus B56 XL, a German-engineered long-arm stapler that reaches deep into the page. It's rated for up to 170 sheets, so it binds thick reports as well as folded brochures. A long handle cuts the effort, a rotating anvil and depth guide help with repeat work, and Novus backs it for 25 years. It costs several times as much as a lever model.

There's no lever to push on the Bostitch Impulse 45, an electric stapler that fires as soon as you slide paper under the head and handles up to 45 sheets. You can pull the stack away right after it fires, and a light warns when staples run low. It carries a seven-year limited warranty. It's loud, needs an outlet, and Bostitch says it isn't built for heavy commercial use.

The Swingline Long Reach places a staple up to 12 inches from the paper's edge, so it can center-stitch a booklet folded from tabloid sheets or fasten tags. It's built for reach, not power, and handles about 20 sheets. A ruler is built into the base, a locking guide repeats the same spot on every set, and the frame is metal with a limited lifetime warranty. The guide doesn't always lock, and it can jam.
