The CB 850 Spiral Binding Machine is highly recommended for occasional, private use. It is easy to store in a cupboard when not in use and gives good results. The operation is not as uncomplicated as with the test winner, but it is also significantly cheaper. In addition, a 4-fold hole punch is integrated.


  • Easy to store
  • Very good binding result


  • Cumbersome threading
  • Slips during punching

The CB 850 Spiral Binding Machine is almost identical in construction to the competitors Peach and ProfiOffice. The CB 850 Spiral Binding Machine can also be used to make 4 holes.


The robust CB 850 Spiral Binding Machine, held in grey and black, is mainly made of metal and hard plastic. With its 3.7 kg and its small dimensions, it is a rather handy device and therefore easy to stow away. Too bad that the punching lever is always upright, otherwise it would take up even less space. Its rubber feet ensure that the device hardly slips.


In my opinion, the punching power of 12 sheets stated by the manufacturer is legitimate. Starting at 10 sheets it will be exhausting to press down the punch lever, but the device makes a robust impression and even punches 12 sheets clean.

The binding device looks stable. Thus, the opening of the binding spine can be precisely and safely controlled. Unfortunately, the tines of the device are tilted a little too far forward. This ensures that there is only a little space between them and the comb of the open spine for threading the sheets. To prevent the threading from becoming too tedious, it is advisable to use a slightly larger spine than recommended in the instructions.

Since the CB 850 Spiralbinder is relatively light, I often needed both hands to operate it - one for punching and one for holding the device. For a small number of sheets, the rubber feet were sufficient to hold it in place. If more force is needed, the device slips or is lifted.

Just like all competitors, except the test winner, the CB 850 Spiral Binding Machine has the characteristic that the lever arm is responsible for both binding and punching. This has the disadvantage that the two activities cannot be carried out simultaneously. When creating larger folders, it is not possible to thread punched intermediate stacks immediately, but only when all the sheets have been punched.

Binding result

The markings on the CB 850 Spiral Binding Machine to know in which position to insert DIN A4 and DIN A5 sheets into the punching chute are very accurate and work well. However, it is difficult to adjust the paper-stop accordingly. You should always check that you have chosen the correct position with lubricating paper before punching important documents. This is because small displacements can cause open holes at the edge or that individual punched stacks are not flush with each other.

In my tests, the CB 850 Spiral Binding Machine delivered clean punched holes. The binding also holds reliably.


The machine has a punching waste compartment that catches the punched paper.

Included in the delivery is the binding material, including comb and front and back, for 25 bindings. In addition, 50 more combs are included.

We have evaluated approximately 100 customer reviews on the Internet. In summary, it can be said that about 65 percent of buyers are satisfied (4 stars) or even very satisfied (5 stars). Partially (2 stars) or completely dissatisfied are about 30 percent of the users. The average score at the time of the evaluation was 3.6 out of 5 stars.
