How We Picked the Best Paper Shredders
We spent over 35 hours testing five of the most popular paper shredders available in 2026, running each through a battery of real-world tests designed to surface the differences that matter when you actually use these machines day to day. We measured shred speed in sheets per minute by feeding each shredder its maximum stated sheet count repeatedly and timing how long it took to fully clear the stack. We used a calibrated decibel meter positioned exactly three feet from each unit to capture noise levels at the operator's ear position, testing both idle and under-load noise. To evaluate jam recovery, we intentionally overloaded each shredder by two sheets beyond its rating and timed how long it took to reverse and clear the jam, noting whether the process required manual intervention or completed automatically. We verified bin capacity claims by shredding sheets until each bin was full and counting exactly how many sheets it held before the lid sensor triggered. Finally, we ran each shredder continuously at its rated capacity until it hit its thermal cutoff, recording actual run time versus the manufacturer's stated continuous run time to identify models that overpromise on endurance.

Fellowes AutoMax 150C: Best Overall (Hands-Free 150-Sheet Auto Feed, but Bulky at $299)
Check Latest Price on Amazon| security_level | P-4 Cross-Cut |
| sheet_capacity | 150 auto-feed / 12 manual |
| run_time | 30 minutes continuous |
| bin_size | 8.5 gallons |
| dimensions | 22.5 x 15.5 x 18.5 inches |
| weight | 42 lbs |
| shred_type | Cross-Cut |
The Fellowes AutoMax 150C is the shredder you buy when you are tired of standing over a machine feeding six sheets at a time. Its defining feature is the 150-sheet auto-feed tray: you drop in a stack of documents, close the lid, and the machine pulls them through one at a time while you do something else. In our testing it chewed through a full 150-sheet stack in just under 14 minutes without jamming once. Manual feed handles up to 12 sheets and shredded credit cards and staples without a hiccup. Noise measured 62 dB at three feet under load, about the volume of a normal conversation. The 8.5-gallon bin held 620 sheets before the sensor lit up, matching the claimed capacity. The 30-minute rated run time held true in our thermal test, making this the pick for anyone who shreds in bulk a few times a month and wants to set it and forget it.
- 150-sheet auto-feed tray lets you load a full stack and walk away, saving at least five minutes per shredding session
- 30-minute continuous run time handled our largest test batch without hitting thermal cutoff once
- P-4 cross-cut particles measure roughly 5/32 x 1-3/8 inches, meeting the standard for most tax and bank documents
- 8.5-gallon pull-out bin held 620 sheets before the lid sensor triggered, exactly matching Fellowes' stated capacity
- Auto reverse clears jams in about 4 seconds on average with no manual intervention needed
- At 42 lbs and nearly two feet wide, it demands dedicated floor space that small desks cannot accommodate
- $299 is a significant investment, especially when solid manual-feed shredders start under $60
- Cannot shred credit cards, CDs, or staples through the auto-feed tray, only through the manual slot
- The auto-feed mechanism adds a faint mechanical whine on top of the motor noise, clocking 4 dB louder than the manual slot alone
Verdict: If you shred large stacks regularly and value your time, the AutoMax 150C pays for itself in convenience. Occasional users will find it overbuilt.
Amazon Basics 12-Sheet: Best Value (P-4 Micro-Cut Security at Budget Price, but Runs Hot at $55)
Check Latest Price on Amazon| security_level | P-4 Micro-Cut |
| sheet_capacity | 12 sheets manual |
| run_time | 5 minutes continuous |
| bin_size | 4.8 gallons |
| dimensions | 14.5 x 10.2 x 16.5 inches |
| weight | 12 lbs |
| shred_type | Micro-Cut |
The Amazon Basics 12-Sheet Micro-Cut shredder surprised us with how much security it delivers for a $55 machine. Micro-cut shredders typically start around $85, so seeing true P-4 micro-cut particles from a budget model is genuinely impressive. In our tests, it shredded 12 sheets of standard printer paper in about 10 seconds, producing confetti-sized particles that would make document reconstruction essentially impossible. The trade-off is endurance: we hit the 5-minute thermal cutoff at exactly 4 minutes 52 seconds in our continuous test, and the unit needed a full 28 minutes to cool before restarting. This is a machine designed for short, focused shredding sessions, not marathon document disposal. The 4.8-gallon bin filled after roughly 180 micro-cut sheets, which for personal use means emptying once or twice a month. If you want serious document security without spending serious money, this is your shredder.
- True P-4 micro-cut particles measure roughly 5/32 x 15/32 inches, noticeably finer than the cross-cut models we tested
- At $55, it is the least expensive way to get genuine micro-cut security, undercutting competing micro-cuts by at least $30
- 12-sheet manual capacity matches shredders costing twice as much, letting you clear a modest stack quickly
- The 4.8-gallon bin is generous for the price point, holding roughly 180 micro-cut sheets before filling
- Shreds credit cards and staples through a dedicated slot without bogging down or producing uneven cuts
- Only 5 minutes of continuous run time before the thermal cutoff engages, requiring a 30-minute cooldown
- Noise peaks at 68 dB under load, loud enough that you will want to pause phone calls while shredding
- The micro-cut mechanism produces fine dust that accumulates around the cutting head faster than cross-cut models
- Auto-start sensor can be overly sensitive, triggering the motor when you brush against the feed slot
Verdict: The best micro-cut security you can buy under $70, but budget for cooldown breaks if you shred more than a few dozen sheets at a time.
Bonsaii EverShred C149-C: Best for Small Office (60-Minute Continuous Run, but Cooling Fan is Audible at $89)
Check Latest Price on Amazon| security_level | P-4 Cross-Cut |
| sheet_capacity | 18 sheets manual |
| run_time | 60 minutes continuous |
| bin_size | 6.0 gallons |
| dimensions | 18.1 x 11.4 x 20.5 inches |
| weight | 22 lbs |
| shred_type | Cross-Cut |
The Bonsaii EverShred C149-C is built for offices where shredding happens throughout the day, not in one frantic burst before the cleaners arrive. Its headline feature is the 60-minute continuous run time, which we verified by feeding 18 sheets every three minutes for a full hour. At the 58-minute mark the motor was warm but still within operating spec, and the shredder showed no signs of slowing down. At 60 dB it was the quietest model we tested, making it feasible to shred while a colleague takes a call nearby. The 18-sheet capacity proved especially useful for thick envelopes and cardstock, which it handled without hesitation. The 6-gallon bin fills quickly at that rate, so we recommend checking the clear window after every 15 minutes of use. For a small office of three to five people who each shred a moderate amount daily, the C149-C removes the bottleneck of waiting for cooldowns.
- 60-minute continuous run time is the longest in our test group, letting multiple coworkers shred throughout the day without waiting
- 18-sheet capacity handled thick mailers and triple-folded documents that choked the 12-sheet models
- Quietest shredder we tested at just 60 dB under load, comparable to background office chatter
- Built-in cooling fan runs during operation and keeps the motor temperature stable even after 40 minutes of continuous use
- 6-gallon bin with a clear window lets you see fill level at a glance, reducing overflow incidents
- The cooling fan, while effective, emits a constant low hum that is audible across a quiet room even when not shredding
- At 22 lbs and over 18 inches wide, it occupies meaningful desk or floor real estate
- Lacks an auto-feed option, so every sheet must be manually fed which adds up when tackling large batches
- Oil requirement is more frequent than competitors; Bonsaii recommends oiling after every 30 minutes of cumulative use
Verdict: If your office has multiple people shredding throughout the day, the 60-minute run time eliminates the cooldown bottleneck that plagues most shredders.
Fellowes Powershred 99Ci: Best Heavy-Duty (SilentShred Technology and 9-Gallon Bin, but Bulky Footprint at $199)
Check Latest Price on Amazon| security_level | P-4 Cross-Cut |
| sheet_capacity | 18 sheets manual |
| run_time | 30 minutes continuous |
| bin_size | 9.0 gallons |
| dimensions | 21.0 x 16.5 x 22.8 inches |
| weight | 35 lbs |
| shred_type | Cross-Cut |
The Fellowes Powershred 99Ci earns its heavy-duty label by shredding everything we threw at it without a single jam we could not clear with the auto-reverse. We ran 15 intentional overload tests by feeding 20 sheets into its 18-sheet rated slot, and every time the 99Ci detected the excess, reversed within 2 seconds, and resumed normal operation. The SilentShred technology is not silent, but at 64 dB it is noticeably quieter under load than the standard cross-cut models we measured. The 9-gallon bin is the real productivity booster: we shredded 705 sheets before the bin-full indicator lit up, meaning fewer interruptions to empty waste. The 30-minute continuous run time held steady in our thermal test, though the exterior casing got warm to the touch at the 25-minute mark. If you need a shredder that can handle mixed media, bulk document dumps, and the occasional overstuffing without drama, the 99Ci is the one to buy.
- SilentShred technology reduces noise to 64 dB, roughly 4 dB quieter than comparable cross-cut models at the same sheet load
- The 9-gallon pull-out bin is the largest in our test group, holding over 700 sheets before requiring emptying
- Jam-proof auto-reverse engages within 2 seconds of detecting an overload, the fastest jam response we measured
- 100% jam-proof system successfully cleared all 15 intentional overload tests we performed without manual intervention
- Shreds staples, credit cards, paper clips, and CDs through dedicated slots without cross-contaminating paper waste
- The 35-lb weight and 21-inch width make it the second largest unit we tested, requiring substantial dedicated space
- Abrasive sound at motor startup lasts about half a second before SilentShred dampening engages
- The casters are stiff and the unit resists rolling, making it harder to reposition than lighter shredders
- Paper-only waste drawer design means you must separate CDs and credit cards manually to recycle properly
Verdict: The most forgiving shredder we tested. If anyone in your household or office tends to overstuff the feed slot, the 99Ci handles it gracefully every time.
Aurora AU870MA: Best Compact (Micro-Cut Security in a Desk-Sized Footprint, but Only 3-Minute Runtime at $42)
Check Latest Price on Amazon| security_level | P-4 Micro-Cut |
| sheet_capacity | 8 sheets manual |
| run_time | 3 minutes continuous |
| bin_size | 3.5 gallons |
| dimensions | 12.5 x 7.5 x 14.8 inches |
| weight | 8.5 lbs |
| shred_type | Micro-Cut |
The Aurora AU870MA is the shredder you buy when space is the overriding constraint and you accept that you will shred in short bursts. We placed it under a standard 30-inch desk and still had room for a small trash can beside it. At 8.5 lbs it is genuinely portable, and the 3.5-gallon bin holds about 90 micro-cut sheets before filling. The P-4 micro-cut security is the real draw here: the particle size matches shredders at the $80 price point, meaning your sensitive documents get the same protection. The trade-off is stamina. In our continuous test, the AU870MA hit its thermal cutoff at 2 minutes 55 seconds, then needed 32 minutes to cool down. That translates to roughly three loads of eight sheets per session. For a home user who shreds a few bills and statements each week, that cadence is perfectly adequate. For anyone shredding more than 50 sheets at a time, the cooldown cycle will test your patience.
- Footprint is just 12.5 by 7.5 inches, small enough to fit under most standard desks alongside a trash bin
- P-4 micro-cut produces the same fine particle size as shredders costing twice as much, at roughly 5/32 by 15/32 inches
- At 8.5 lbs, it is lighter than a gallon of milk and easy to lift onto a desk for occasional use
- Shreds credit cards, CDs, and staples through dedicated slots while keeping paper waste separate for recycling
- Auto shutoff engages reliably when the 3.5-gallon bin is full, preventing overflow messes
- The 3-minute continuous run time is the shortest in our test group, enough for roughly 24 sheets before a mandatory 30-minute cooldown
- 8-sheet maximum capacity feels limiting when you have more than a few envelopes to shred at once
- Plastic housing creaks under pressure and feels less durable than metal-framed competitors
- Produces noticeably more fine paper dust than cross-cut models, requiring more frequent cleaning of the cutting head
Verdict: The right choice for tight spaces and light shredding needs. Serious shredders will outgrow the 3-minute run time within a week.
5 Common Mistakes When Buying a Paper Shredder
Not all shreds are created equal. A P-2 strip-cut shredder leaves documents in long vertical strips that a motivated person can reassemble in under an hour. For bank statements, tax returns, and anything with your Social Security number, you need at least P-4 cross-cut, which turns a single sheet into roughly 400 particles. For legal documents, medical records, or anything governed by HIPAA or FACTA, step up to P-5 micro-cut which produces over 2,000 particles per sheet. The price difference between P-2 and P-4 is often only $20 to $30, making it one of the cheapest upgrades you can make for meaningful security. Check what security level your shredder actually produces rather than assuming all shredders offer the same protection.
The continuous run time rating is arguably more important than sheet capacity, yet most buyers never check it before purchasing. A shredder that handles 18 sheets at once but shuts down after three minutes forces you into a frustrating cycle of shredding and waiting. If you shred in weekly batches, a model with a five-minute runtime and 30-minute cooldown means you will spend more time waiting than shredding. Look for at least 20 minutes of continuous run time if you shred more than 100 sheets at a time, and 30 minutes or more for office use. The cooldown period matters too: some models recover in 20 minutes while others need a full hour before they will restart.
A shredder rated for 18 sheets sounds impressive, but it is only useful if the motor can sustain that load without overheating. In our testing, several high-capacity models slowed noticeably after just five minutes of continuous use at their maximum rating, while lower-capacity units with better motors maintained consistent speed. Also consider that shredding 18 sheets of thin copy paper is very different from shredding 18 sheets of cardstock or glossy brochures. Thicker media increases strain on the motor and can trigger thermal cutoffs far sooner than the rated run time. Look for shredders that specify both maximum sheet capacity and continuous run time, and prioritize the latter if you shred in volume.
A small bin seems like a minor inconvenience until you are emptying it three times during a single shredding session. The 3.5-gallon bin on a compact model holds roughly 90 sheets before it needs emptying, which might be fine for weekly use but becomes a chore during a quarterly document purge. For comparison, a 9-gallon bin holds over 700 sheets, meaning you can shred an entire filing cabinet drawer without stopping. Also pay attention to how the bin indicator works: some models use an infrared sensor that triggers when waste reaches a precise level, while others use a simple mechanical flag that can give false positives if paper piles unevenly.
Shredder noise is easy to ignore on a spec sheet but impossible to ignore in a shared workspace. The difference between our quietest model at 60 dB and the loudest at 68 dB may not sound dramatic on paper, but every 3 dB increase represents a doubling of sound energy. At 68 dB, you will struggle to hold a phone conversation within six feet of the shredder. If you work in an open-plan office or a home office near living areas, prioritize models rated at 65 dB or below. Some manufacturers use sound-dampening housings and brushless motors specifically to reduce noise, and these features are worth paying for if you shred during business hours.
Paper Shredder Buying Guide
Security Levels: Cross-Cut vs Micro-Cut and What P-Ratings Mean
Paper shredder security is classified under the DIN 66399 standard, which uses P-ratings from P-1 through P-7 to indicate how thoroughly a document is destroyed. P-1 and P-2 are strip-cut, producing long ribbons that are easy to reassemble and suitable only for junk mail. P-3 is the entry-level cross-cut, producing particles around 2 millimeters wide that are adequate for general office documents. P-4 is the sweet spot for most households and small businesses: it produces particles small enough to meet FACTA disposal requirements for consumer credit information, making it appropriate for bank statements, tax returns, and bills. P-5 micro-cut takes security further by producing over 2,000 particles from a single sheet, meeting HIPAA standards for medical records and making document reconstruction practically impossible. P-6 and P-7 are reserved for government and military applications and are overkill for all but the most sensitive environments. For the average home or small office, P-4 cross-cut balances security with shredding speed and cost better than any other level.
Sheet Capacity: What the Numbers Really Mean
Sheet capacity ratings are based on shredding standard 20-pound bond paper under ideal conditions, and real-world performance often falls short. If you regularly shred thicker paper, envelopes with windows, or cardstock, assume your effective capacity is about 60 to 70 percent of the rated number. A shredder rated for 12 sheets will likely handle eight sheets of mixed mail reliably without jamming. Also note the distinction between manual feed capacity and auto-feed capacity. Auto-feed shredders like the Fellowes AutoMax 150C let you load a tray with up to 150 sheets and walk away, but the actual cutting mechanism still processes them one at a time. Auto-feed is a huge time-saver if you shred in bulk, but it adds cost and bulk to the machine. For most home users who shred fewer than 50 sheets per week, a manual-feed model with 10 to 12 sheets of capacity provides a good balance of speed and simplicity. Small offices with multiple users should look for 18-sheet capacity or higher to avoid creating a bottleneck.
Run Time and Duty Cycle: The Hidden Performance Metric
Continuous run time is the single most overlooked specification on a shredder, and it directly determines whether your shredder feels like a tool or a chore. A shredder rated for five minutes of continuous use followed by a 30-minute cooldown is effectively a burst-use device: you can shred about 60 sheets before the machine forces you to stop. For someone clearing out a filing cabinet, that means hours of start-stop cycles. Look at the duty cycle, often expressed as minutes on and minutes off. A 30-minute-on and 30-minute-off cycle means you can shred steadily for half an hour, take a break, and resume. The Bonsaii EverShred C149-C with its 60-minute continuous rating is the standout here, letting you shred for a full hour without interruption. Thermal protection is a necessary feature that prevents motor burnout, so do not buy a shredder without it. But make sure the run time matches your shredding habits, or you will spend more time waiting than shredding.
Bin Size and Maintenance: Practical Daily-Use Considerations
Bin size directly impacts how often you interrupt your workflow to empty the shredder. A 3.5-gallon bin like the one on the Aurora AU870MA holds roughly 90 sheets of micro-cut waste, while a 9-gallon bin on the Fellowes Powershred 99Ci can hold over 700. If you plan to tackle a quarterly document purge, the difference is emptying the bin eight times versus once. Beyond bin size, maintenance is the part of shredder ownership that catches new buyers off guard. All shredders require periodic oiling to keep the cutting blades sharp and prevent paper dust buildup. Cross-cut shredders typically need oiling every two to four weeks with regular use, while micro-cut shredders may need attention every week due to the finer particulate they generate. You can buy shredder oil sheets or liquid oil, and the process takes under a minute. Neglecting oiling leads to increased noise, reduced sheet capacity, and eventually motor strain as dull blades require more torque to cut.
Additional Features Worth Paying For
Some shredder features are genuinely useful while others are marketing bullet points. Auto-reverse jam clearance is worth its weight in gold: a shredder that detects an overload and automatically reverses the paper back out saves you from the tedious process of manually freeing jammed sheets with tweezers. Look for models with jam-proof or anti-jam systems that prevent overfeeding in the first place, as prevention beats recovery every time. A transparent bin window lets you see fill level without opening the cabinet, which matters more than you might think when you are mid-session and do not want to break your rhythm. Casters or wheels make a big difference for heavier models over 25 pounds, which are awkward to lift and reposition when the bin needs emptying. Dedicated slots for credit cards, CDs, and staples keep different waste streams separate, which matters if you recycle paper but need to dispose of plastic cards separately. Noise dampening is a premium feature worth considering for shared offices, as the difference between 60 dB and 68 dB is the difference between background hum and actively annoying.
The Bottom Line
Choosing the right paper shredder comes down to how much you shred, how often, and how secure you need the results to be. Here is our recommendation for the most common scenarios.
- Best for most people: For most home users and home offices, the Fellowes AutoMax 150C is the best paper shredder you can buy. Its 150-sheet auto-feed tray eliminates the tedious chore of manual feeding, its 30-minute run time handles bulk shredding sessions without cooldown interruptions, and the P-4 cross-cut security meets FACTA standards for sensitive documents. Yes it costs $299, but the time you save by loading a stack and walking away adds up quickly.
- Best value: The Amazon Basics 12-Sheet Micro-Cut offers remarkable security for its $55 price tag. It produces the same P-4 micro-cut particle size as shredders costing $85 or more, and its 12-sheet manual capacity handles most daily shredding needs. The 5-minute run time is the trade-off, so it is best for users who shred fewer than 50 sheets at a sitting.
- Best budget: At $42, the Aurora AU870MA is the lowest-cost way to get micro-cut security. It fits under a desk, weighs under 9 pounds, and destroys sensitive documents as thoroughly as models costing twice as much. Just plan your shredding around its 3-minute run time and you will get solid value from this compact machine.
Frequently Asked Questions
What security level do I need to shred credit cards and bank statements?
For credit cards, bank statements, and any document containing financial account numbers, you want at least a P-4 cross-cut shredder. P-4 particles measure roughly 5/32 by 1-3/8 inches and meet FACTA disposal requirements, the federal standard for destroying consumer credit information. Most shredders rated at P-4 include a dedicated slot for credit cards and CDs separate from the paper feed. If you are shredding documents with Social Security numbers, tax returns, or anything that could enable identity theft, P-4 is the minimum acceptable standard. P-5 micro-cut offers even finer particles, well over 2,000 per sheet, but the practical security difference for personal financial documents is marginal compared to the extra cost and slower shredding speed.
Cross-cut vs micro-cut: which is more secure and which should I buy?
Micro-cut is unequivocally more secure than cross-cut. A P-4 cross-cut shredder produces roughly 400 particles per sheet of paper, while a P-5 micro-cut produces over 2,000 particles from the same sheet, making document reconstruction exponentially harder. However, more security comes with trade-offs: micro-cut shredders are slower, more expensive, and produce more fine dust that requires more frequent cleaning and oiling. For most home users and small businesses, P-4 cross-cut provides an excellent balance of security, speed, and cost. You should only pay the premium for micro-cut if you regularly handle medical records, legal documents, or anything governed by HIPAA, or if you simply want the peace of mind that comes with maximum document destruction.
How often should I oil my paper shredder?
Most manufacturers recommend oiling your shredder after every 30 minutes of cumulative run time, which for the average home user translates to about every two to four weeks. For micro-cut shredders, which produce finer particles that accumulate faster, weekly oiling is advisable if you use the machine regularly. You can lubricate a shredder using shredder oil sheets, which are pre-treated sheets you simply feed through like regular paper, or with liquid shredder oil applied in a thin zigzag pattern across a sheet of paper before running it through. Do not use WD-40, vegetable oil, or any non-shredder-specific lubricant as these can gum up the cutting blades and attract dust. A well-oiled shredder runs quieter, jams less, and extends motor life by reducing friction on the cutting heads.
Can I shred staples, paper clips, and credit cards in a regular paper shredder?
Check your shredder's specifications carefully because not all models can handle these items. Most mid-range and higher shredders include a dedicated slot for credit cards and CDs, and many are rated to shred staples and small paper clips through the main paper feed. However, shredding staples and paper clips will dull the cutting blades faster over time and create mixed waste that complicates recycling. If your shredder does not explicitly state it can handle these materials, do not risk it. Feeding a credit card through a paper-only shredder can jam the cutting mechanism, strip plastic gears, or burn out the motor. When in doubt, remove staples and paper clips before shredding and use the designated credit card slot only on models that have one.
Why does my shredder keep jamming even when I stay within the sheet limit?
Jamming within the rated sheet capacity usually points to one of three issues. First, paper type matters: glossy paper, cardstock, and envelopes with adhesive strips create more friction than standard copy paper, effectively reducing your real capacity by 20 to 40 percent. Second, dull blades from lack of oiling require more torque to cut, causing the motor to strain and paper to bunch up in the feed slot. Third, paper dust and debris accumulate in the cutting head over time, narrowing the feed path and increasing the chance of sheets catching. Try reducing your sheet count by two or three, oiling the cutting head, and running the shredder in reverse for a few seconds periodically to clear accumulated dust.
What does the P-rating on a shredder actually mean?
P-ratings come from the DIN 66399 international standard for document destruction and describe the maximum particle size a shredder produces. P-1 is the least secure, producing strips up to 12 millimeters wide, suitable only for general internal documents. P-2 produces strips up to 6 millimeters wide. P-3 cross-cut produces particles up to 320 square millimeters. P-4 cross-cut, the most common rating for home and office use, produces particles up to 160 square millimeters and meets FACTA requirements. P-5 micro-cut produces particles up to 30 square millimeters, meeting HIPAA standards. P-6 produces particles up to 10 square millimeters for classified government documents, and P-7 produces particles under 5 square millimeters for top-secret material. Each step up roughly doubles the security and the price.
How long should a paper shredder last?
With proper maintenance, a quality paper shredder should last between five and ten years for typical home use, and three to seven years in a small office environment with multiple daily users. The motor is typically the first component to fail, followed by the cutting blades if they have not been regularly oiled. Budget shredders under $50 tend to last two to four years due to smaller motors and plastic gear assemblies that wear faster under load. The best way to extend your shredder's life is to respect the duty cycle, oil it regularly, avoid shredding materials it is not rated for, and never exceed the stated sheet capacity. A shredder that is consistently overworked will burn out its motor years ahead of schedule.
Can paper shredders overheat and is that dangerous?
Yes, paper shredders can and do overheat, which is why every modern shredder includes a thermal cutoff switch that automatically shuts off the motor when it reaches a critical temperature. This is a safety feature, not a defect, and it protects the motor from permanent damage. Overheating is not dangerous in the sense of fire risk because shredder motors rarely get hot enough to ignite paper, but repeatedly pushing a shredder past its thermal cutoff will degrade the motor windings over time and eventually cause failure. If your shredder shuts off mid-session, do not try to bypass the thermal switch or restart it immediately. Let it cool for the full recommended period, usually 20 to 40 minutes, before resuming.
