Sometimes, you just need to shred some papers. If you want to do that professionally, then you need a professional and heavy-duty shredder.

When you want to shred papers, be it legal documents, files with your personal information on it, or anything else which you do not want prying eyes to see, a shredder will take care of that for you. A heavy-duty shredder is what large companies use to shred all of their documents, and you can have one too.

The good news is that heavy-duty shredders have never been more affordable. With an investment of a few dollars, you can have a great shredder which can last for a very long time.

Let’s take a look at buying a shredder.

Shredding Basics

One of the main ways in which shredders are classified is in how they shred the paper fed into them.

Strip-Cut Shredders

Strip-cut shredders cut the paper into strips. The advantage of this type of shredder is that they are fast and affordable. Cutting paper into strips is relatively inexpensive to do and does not require a lot of components. The downside is that the resulting shreds are not as secure as what you get with some other shredders. If someone is dedicated enough, they can piece the shreds together.

Cross-Cut Shredders

Cross-cut shredders are more secure than strip-cut shredders. They cost a little more due to the parts inside, but they cut the paper into smaller parts. They still cut the paper into strips, but those strips are thinner and shorter.

Micro-Cut Shredders

Micro-cut shredders cut the paper into the smallest pieces, making them extra secure. They cut the paper into small diamond-shaped pieces, kind of like pieces of confetti. This makes them great for secret or confidential papers, and it is almost impossible to piece them back together.

Shredder Security

When it comes to shredders, one thing which you should be concerned about is the security they give when shredding papers. The security depends on the smallness of the paper and is determined by an internationally recognized standard (DIN 66399).

The security standard runs from P-1 (insecure) to P-7 (most secure). In most office settings, you will find that most of the shredders are rated around P-4. For more sensitive information, a rating of P-5 will usually suffice. P-7 would be used for top secret documents which cannot be seen by any prying eyes.

When you are looking for a heavy-duty shredder, think about how much safety and security you need and base your choice on how small the shredder will shred your paper.


When you are shredding your papers, there are a couple of things to think about which will en-hance your shredding experience.

Sheet Capacity

Gone are the days where paper could only be shredded one piece at a time. Welcome to the world of multiple shredded sheets. Not only does this make the shredder more heavy-duty and durable, but it also saves you a lot of time.

Most basic shredders will shred between 1-3 sheets of paper at one time. We are not looking for basic shredders; we want heavy-duty ones. We recommend that you look for a shredder which can handle at least 3 sheets of paper and up to 20 sheets at once.

Tough shredders can also shred more than just paper. If you get a high-quality paper shredder, you can shred your way through credit cards (great for security), staples (in case you forget to take them out), and CDs (if that mixed CD from a previous relationship is causing you emotional pain). A tough shredder can also cut through thick envelopes of junk mail.

Run Time

If you have a lot of papers to shred, then you need your heavy-duty shredder to last for a long time. When we were choosing the best shredders, we only chose the ones which could keep up. So, how long should they run for?

Most shredders can shred for around 20 minutes before they need to cool down. For most of your jobs, this will be enough time but, if you are doing larger jobs, you will need to choose a shredder with a longer run time.

Heavy-duty shredders can run for up to 60 minutes before needing to cool down. If you are doing large jobs, it can be annoying to have to wait while the shredder cools down. Look for a shredder with a long run time and as short a cool-down time as possible.


The speed is partly based on how many sheets of paper can be fed through the shredder but also depends on the capacity of the feeder basket.

The more sheets which can be fed into the shredder, the faster you can work, but you also need to think about the size of the basket. If you can shred multiple documents, but the shredder can not hold much, then you can shred quickly, but you are going to spend a lot of time emptying the basket before you can shred more.

You also need to think about the run time and the cool-down time. If you can only shred for a few minutes and then have to let the machine cool down over a long period of time, then you are going to be slowed down a lot. You may be able to shred quickly, but you are not going to be able to shred a lot.

So, if you want a shredder which is fast, you need to look for one which can shred multiple pages, has a large capacity, runs for a long time, and has a short cool-down time. If you are only looking at some of those things, then we would recommend a large capacity and a long run time.


A larger shredder usually means a larger basket, but that is not always the case. When looking at heavy-duty shredders, you are likely going to have a shredder which will take up a lot of space, but that does not mean that it has to take up too much space.

The best shredders are the ones which compact their shredding capabilities into the smallest space possible. You want a large shredding capacity with as small a footprint as possible, and this is what we have looked for in our choices.

The shredders on the list will get the job done without taking up a massive amount of space.

Other Functionality

If your heavy-duty shredder can shred the paper, then you are good, right? Well, there are some other things to think about to ensure that you never run into problems.


One of the biggest problems with shredders is paper jams. Most durable shredders come with anti-jam technology. This built-in technology prevents the paper from becoming jammed and stuck.

This is usually achieved with sensors in the unit, which will reverse the shredding process and stop the paper from becoming too caught up once it starts to jam. This technology can save you from a lot of headaches.


Shredders cause some noise through the shredding process, but some are better than others. Depending on where the shredder is going to be used, you may want to invest in a shredder which has a lower noise level.

A decibel level below 55 dB will not cause too much noise in a public setting.


To keep your blades in optimum condition, you need to oil them regularly. There are two ways to do this: automatically and manually.

If you do not have the time to oil the shredder blades or if you are worried that you are going to forget, then you should get a shredder which automatically oils the blades for you.
