✅ PROS
- Punches 20 sheets of 20 lb bond paper in under 2 seconds with zero hand fatigue
- Built-in paper chip tray catches all confetti — no more cleaning desk debris
- Adjustable paper guide ensures consistent hole spacing across multiple sheets

- Plastic housing feels less premium than the price suggests compared to metal rivals
The Verdict
If you’ve ever punched 200 sheets for a client binder with a manual three-hole punch, you know the forearm burn. The AFMAT Electric 3-Hole Punch promises to end that misery for about what you’d spend on two mediocre lunches. At 4.7 stars across 235 ratings, it’s clearly doing something right. But is it the right hole punch for your desk?
What’s actually in the box
The AFMAT arrives fully assembled — no setup beyond plugging it in. You get the punch unit itself, a removable chip tray for paper debris, and a paper alignment guide. That’s it. No confusing adapters, no software, no nonsense. The footprint is roughly the size of a small laser printer: about 13 inches long, 8 inches deep, and 5 inches tall. It’s not compact enough to hide in a drawer, but it won’t dominate a standard desk either.
Real-world performance
Here’s where the AFMAT earns its keep. Drop up to 20 sheets of standard 20 lb copy paper against the back guide, press the top button, and the motor drives three hardened steel punches through in roughly two seconds. The holes are clean, evenly spaced at the standard 4.25-inch center distance, and consistent every time. A green indicator light confirms the cycle is complete.
The adjustable paper guide is genuinely useful — slide it to align paper of different sizes (letter, A4, half-letter) so the holes land exactly where you need them. For anyone binding documents regularly, this precision matters. The chip tray catches all the paper dots, and it slides out for easy emptying. One Amazon reviewer put it simply: “I love this hole punch. It’s so much easier than my old manual one and saves my hands.”
What buyers consistently praise
Across the 235 ratings, three themes dominate. First, the speed and effortlessness — “Saves my hands and wrists” appears repeatedly. Second, the consistent hole placement across multi-page stacks. Third, the safety mechanism: the punch won’t activate unless the paper is fully inserted against the back stop. That’s a thoughtful touch for anyone who’s ever accidentally punched their finger with a manual unit.
Where it falls short
Honesty requires the tradeoffs. The AFMAT is AC-powered only — there’s no battery option, so it’s tethered to a wall outlet. If you work from a laptop on the couch, this stays on your desk.
Capacity drops sharply with thicker media. Cardstock, laminated sheets, or 24 lb+ paper will choke it well before 20 sheets. Several reviewers noted this. One wrote: “Works great on regular paper, but struggles with heavier cardstock — you’ll need to halve the stack.” Plan for 8-10 sheets max on anything not standard printer paper.
The build is mostly ABS plastic. It’s sturdy enough for daily office use, but if you’re expecting an all-metal industrial unit, this isn’t that. At its price point, the plastic is acceptable — just know what you’re buying.
Who should buy this
This punch is perfect for three specific people: the home office user who creates binders or proposals weekly, the teacher printing and punching packets for multiple class periods, and the small business owner who’s tired of hand-cranking through client documents. If you punch more than 50 sheets per week, this will pay for itself in saved time and wrist pain.
Skip it if you only punch a few sheets occasionally (a manual punch is cheaper and needs no outlet) or if you regularly punch heavy cardstock (look for a punch rated for 40+ sheets of heavy stock).
FAQ
Does it punch through 20 sheets of 24 lb paper?
No. The 20-sheet rating assumes standard 20 lb bond. Drop to 10 sheets for 24 lb, and even fewer for cardstock.
Can I punch half-letter or A5 paper?
Yes — the adjustable guide handles various widths. Just slide it to the correct position before punching.
Is the chip tray easy to clean?
Yes. It slides straight out, and the paper dots dump into any trash bin. No prying or shaking required.
The Verdict
Buy it if you’re tired of manual punching and process regular paper in volume. Skip it if you need portability, punch heavy cardstock, or only punch occasionally.
The AFMAT Electric 3-Hole Punch delivers exactly what it promises: effortless, consistent three-hole punching for standard office paper. At 4.7 stars with 235 ratings, the consensus is clear — this is the upgrade your wrists have been asking for.
