In our test , the Kairon blade recept acle pliers incl. blade receptacle assortment from Baurix made a good impression overall. The set consists of the blade receptacle pliers, an assortment box with three different types of blade receptacles and blade plugs with the corresponding insulation. Unfortunately, the number of blade receptacles does not match the specifications, but the set performed well in the practical test. The high-quality pliers can be used to crimp the blade receptacles, although this is only possible without problems from a cable cross-section of 0.75 mm². The blade terminals and blade receptacles hold together very well with the cables. The plug connections also engage firmly and can be separated again. Unfortunately, a small gap remains between the insulation on both sides in the middle of the plug connection.

The Kairon flat receptacle pliers with flat receptacle assortment from Baurix arrived together with another product in the same shipping envelope. The shipping envelope was compact and the individual products had no room to slide around. The shipping envelope contained the product packaging made of white cardboard. The product packaging was undamaged and in perfect condition. The shipping envelope could be opened easily without tools. The product box was sealed with a sticker, so a knife is recommended to open it.
The product box contains a sorting case with the flat receptacle assortment, another box with the flat receptacle pliers, instructions for use, a discount voucher for the next order and a flyer with Internet addresses for warranty registration and an introductory video. It also contains an insert to prevent the box containing the pliers from sliding around. Like the product packaging, the box with the pliers is also sealed with a fixed sticker. The sorting case is also shrink-wrapped in a transparent plastic film. Overall, the components of the set are excellently protected from damage during transportation thanks to the very extensive packaging. Unfortunately, this results in a lot of waste, which is why we believe that the plastic film around the sorting case and the additional packaging for the pliers could have been dispensed with.

The set consists of the blade receptacle pliers and an assortment box, which contains three different types of blade receptacles and three different types of blade plugs. There are also a corresponding number of three different types of insulation for the sleeves and one type of insulation for the plugs. According to the manufacturer, the set contains a total of 300 parts. The blade receptacles are sensibly arranged in the assortment box. Unfortunately, the stated number of parts is not exactly correct. A count of the type 4.8 blade terminals shows 49 instead of the stated 50, while the insulation for type 4.8 blade receptacles actually contains 56 instead of the stated 50. However, this can be overlooked due to the high total number of blade receptacles. The pliers and the many different sizes of blade receptacles provide the customer with a comprehensive set.
The instructions for use are written in several languages, including German and English. They are clearly written and explain how to use the pliers and blade receptacles.
Contact information can be found on the outside of the assortment box and in the instructions for use. It includes the company name, address, website, telephone number, Whatsapp contact and e-mail address. If you require assistance, please contact us explicitly.

The assortment box is made of transparent plastic. The upper part functions as a lid and has a label printed on both sides. On the outside, there is a list of the contents in addition to the key data and contact details. On the inside there is an assignment of the individual sizes to the respective compartment in the lower part of the box. There are also two buckles on the lid, which can be used to open and close the lid.
The lower part of the box is divided into 18 individual compartments in which the blade receptacles, blade plugs and insulation are sorted. The individual types of insulation use several compartments. Overall, the assortment box is sufficiently sturdy, well made and very practical.
The blade terminals and blade receptacles are each one-piece and made of brass-colored metal. They both have an open cable holder at the end, into which the wires of the cable can be laid. The wider plug-in part is connected directly to this. The blade terminals and blade receptacles are stable and can hardly be deformed by hand. The workmanship is good.
Spade connectors and blade receptacles are both available as types 2.8, 4.8 and 6.3. The number indicates the mating width in millimetres. The mating thickness also varies accordingly and is between 0.25 mm and 0.4 mm. Type 2.8 is suitable for cable cross-sections between 0.5 mm2 and 1.5 mm2, the other two types for cable cross-sections between 0.75 mm2 and 1.5 mm2.
The insulation is transparent, soft and easily deformable. Separate insulations are available for the individual types of blade receptacles. These consist of a section with a circular cross-section for the cable, which merges into a section with an elongated cross-section for the plug connection. The size of the section for the plug connection varies according to the size of the different types. Only one type of insulation is available for the blade terminals, which has a circular cross-section throughout. The workmanship of the insulation is also good.
The blade terminal pliers are made of black metal and have a red-orange plastic handle to make it easier to squeeze. The pliers consist of four parts which are connected by joints. The receptacles for the blade receptacles differ for different cable cross-section ranges. Although no corresponding plugs are supplied, the pliers also have a receptacle for cable cross-sections between 1.5 mm² and 2.5 mm². The pliers also have a latching mechanism which ensures that the cable lug is sufficiently pressed. An associated emergency release is also available. The crimping force can be adjusted using an adjustment mechanism , for which a Phillips screwdriver is required. Overall, the pliers make a high-quality and robustimpression.
This is what our practical test showed
Does the manufacturer keep its advertising promises?
ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Pressing process and pliers | Medium force required, crimping only works without problems from a cable cross-section of 1 mm² | 65 points |
| Variability of the set | Different blade receptacles for a wide range of cable cross-sections | 100 points |
| Holding the blade terminal | Spade connectors and blade receptacles hold firmly together with the cable | 100 points |
| Quality of the plug connection | High-quality appearance, good cohesion, easy separation | 100 points |
| Insulation quality | Easy to slide on, good hold, but a gap remains between the blade receptacle and blade terminal | 70 points |
| Total | 87 points |
*The maximum score is 100 points
In the practical test, we use the set to connect cables of different cross-sections with the flat connectors. In the first step, it is advisable to push the appropriate insulation onto the cable ends. Once the connectors have been crimped, the insulation can only be pushed onto the connectors from the cable side. We start with a type 4.8 blade receptacle. Now the relevant cable end must be stripped to such an extent that the exposed wires pass through the receptacle of the blade receptacle. The next step is to insert the blade receptacle into the pliers. The holder of the pliers has a wide and a narrow side. The side of the flat receptacle that points towards the cable must be placed towards the wide side. The pliers can now be pressed in about halfway so that the flat receptacle no longer falls out. The latching mechanism, which holds the pliers together, helps here. The cable is then inserted into the receptacle of the blade receptacle in the pliers so that the insulation of the cable ends at the transition between the wide and narrow areas.
The pliers can now be fully closed until the crimping of the blade receptacle is complete. The force required is medium, but can be achieved without any problems. The pliers make a stable impression. The latching mechanism makes it easy to handle. The emergency release of the pliers also works perfectly. After crimping, the final step is to push the insulation over the blade terminal sleeve.
The procedure is identical for the blade terminals; there are no differences to crimping the blade receptacles. While the crimping of types 4.8 and 6.3 with cables of 1 mm² cross-section succeeds without any problems, the cable holder of the blade terminal breaks when crimping type 2.8 with a cable of 0.5 mm². This can be reproduced in several tests. However, crimping is successful in the receptacle for cable cross-sections between 1 mm² and 1.5 mm². However, the blade terminal can then be easily removed from the cable. For this reason, it must be crimped again with the actually suitable receptacle. The blade terminal is then difficult to pull out of the pliers, but is firmly connected to the cable.
With larger cable cross-sections, blade terminals and blade receptacles are firmly connected to the cables even without this procedure. The insulation also adheres well to the blade terminals and blade receptacles. The brass-colored blade receptacles in the transparent insulation also ensure a high-quality look.
The blade terminals and blade receptacles can be plugged together without any problems. The plugs snap into place in a defined manner and hold firmly together. They can also be removed again without any problems. The only criticism of the plug connection is the insulation: there is a small gap of around one millimeter between the insulation of the blade terminal and that of the blade receptacle. Longer insulation on the blade receptacle would remedy this.

| Total | 75 points |
*The maximum score is 100 points
On the Amazon platform, consumers have given the product an average rating of 4.6 stars. One common criticism is that crimping is not successful with small cable cross-sections, which was also shown in our test. Production faults on the pliers are also criticized, which our pliers did not have. Many customers like the quality of the customer service and the high-quality pliers, which we can confirm in our practical test.
Prices of up to €39.99 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €18.99. The Kairon flat ferrule pliers with flat ferrule assortment from Baurix currently has a price of €29.99 and is therefore in the middle price segment. The price ratio is reasonable for the quality and scope of the product.
