Bolt Cutters Comparison 2018


Purchase advice for the bolt cutter comparison or test 2018

  • Bolt cutters are tools used to cut metals. You will u. a. used on construction sites and home improvement to cut bolts, screws, nails, wires or similar metal bodies.
  • Depending on the length, type of application and function, three different types of bolt cutters can be distinguished: one-hand mini-bolt cutters (around 200 millimeters), two-hand bolt cutters (from around 300 millimeters) and battery-operated hydraulic bolt cutters.
  • Important indicators of the performance of bolt cutters are on the one hand the diameter of the object to be cut, on the other hand its hardness. The higher the values, the harder it is to cut the material with the multifunction tool.

When the word bolt cutter falls, many will probably first think of bicycle theft. This is not surprising since bolt cutters are often used by bicycle thieves to crack bicycle locks. In 2015, 32,245 bicycles were stolen in Berlin alone. No wonder, then, that the term bolt cutter has a rather dubious reputation. But even if it is not intended as a multi-functional tool of course for thefts, it was designed especially for the cutting of metallic materials. No matter if a crooked nail, an oblique bolt, a motorcycle lock, an Abus lock or a bicycle lock: A bolt cutter overcomes almost every resistance.

Assignment of the bolt cutter

A bolt cutter, also called bolt cutter, belongs to the family of pliers. Unlike traditional pliers designed to grip and pull out, however, the bolt cutter is used to cut and cut metals.

Since bolt cutters are versatile tools, they should not be missing in any well equipped toolbox. So if you want to equip your tool bag sustainably and profitably, you might find it in our bolt cutter comparison 2018 in search of your personal bolt cutter test winner. We have compared the best bolt cutters and tell you why bolt cutters are not only the hit with bicycle thieves, but - as well as the side cutter - are extremely useful tools for every craftsman and hobby handyman.

1. How is a bolt cutter constructed and how does it work?

A bolt cutter is a simple hand tool: It consists of a long handle and relatively short cutting surfaces (baking)into which the workpiece to be machined is inserted. Of many other types of pliers, the bolt cutter differs above all in that it has several joints (inner and outer axes of rotation), which serves to support the lever law.

Bolt Cutters Comparison 2018: bolt

Bolt cutters are not only used for cracking bicycle locks, but generally for cutting metals.

In order to have the highest possible and effective power transmission, after opening the jaws, the object to be cut (eg nails, wire, padlock, bicycle lock or cable) should be placed as close as possible to the joint, as this allows easy bolting even with little effort and other metallic objects can be severed.

What advantages and disadvantages a bolt cutter has over a side cutter can be found in the following overview:

  • higher cutting force
  • better power transmission and thus less effort
  • not only suitable for thin wires, but also thick bolts
  • bigger and bulkier
  • higher weight
  • usually more expensive to buy

2. Bolt cutter types at a glance

When examining a bolt cutter test or comparison, you will notice that most bolt cutters can be categorized into different categories, regardless of brand and manufacturer:

  • The Mini Bolt Cutter is a one-handed model with a short handle (around 200 millimeters).
  • The mostly small cutting surface is more suitable for thinner materials.
  • The short grip leads to a rather low level of leverage.
  • If the bolt cutter is small, it can be used well in hard-to-reach places.
big bolt cutter

  • Electric (battery operated) hydraulic bolt cutters are operated with one hand.
  • Thanks to the battery-powered power supply, no effort is needed.
  • Such models are often very expensive to buy.
  • The device is mainly used as a professional device.

3. Purchase criteria for bolt cutters: You must pay attention to this!

If you want to buy a bolt cutter, you should first of all deal with the most important purchase criteria. In our purchase advice, we give you important tips about this tool and tell you what to look for when buying a bolt cutter.

3.1. Length as an indicator of leverage

Bolt Cutters Comparison 2018: bolt

One-handed mini bolt cutter for cutting thin nails, wires or screws.

In every bolt cutter test or comparison, you will stumble across different lengths. For example, there are models with a total length of 200, 300, 450, 600, 610, 760, 900 or 910 millimeters (just to name a few). The general rule: The higher the length, the greater the leverage effect of the bolt cutter.This means that a longer lever with the same force theoretically develops a higher cutting force.

In addition, other factors also play an important role in practice: So u. a. The blades have a high quality and close evenly when merging. If this is not the case, the force can not be transmitted evenly to the medium to be divided, whereby the cutting is considerably more difficult.

For the intended use, it is also not insignificant whether your bolt cutter is angled. This means that the head of the cutter kinks at a certain angle, so that it can be placed on the ground, for example, to be able to cut vertically protruding nails or bolts horizontally and flat above the ground.

Because of the many different lengths available, you should always consider what you want to use your bolt cutter before buying. In an interview with lets-rebuild.com, expert Jürgen Steinhauer pointed out the possible uses of different bolt cutters:

"For general operations, such as trimming threaded rods or cutting thicker wires (e.g., gabions), bolt cutters having a length of between 600 and 760 millimeters are used. Anyone who works on the construction site and has to cut off rebars can use specimens with over 900 millimeters. To take along in the tool case tools must not exceed 460 millimeters, for practical carry in the tool belt or folding rule pocket of bib over 250 millimeters long.

Jürgen Steinhauer, Knipex-Werk, C. Gustav Putsch KG

If, for example, you are confronted with home-made nails and screws used in the household, it is generally worth buying a mini-bolt cutter with a length of 200 millimeters. If, on the other hand, you work full-time on the building, then your tool should be able to cut thicker bolts over a length of 600 millimeters or more.

3.2. maximum cutting force

Bolt Cutters Comparison 2018: bolt

Both the hardness of metallic objects and their diameter affect whether the bolt cutter can sever the material.

The maximum cutting force is not a size that is easy to determine with bolt cutters. Nevertheless, the performance of these tools can be judged by being tested on piano wire. This wire, often used in pianos, can be very strong and thick, making it the ultimate challenge for bolt cutters. Two factors must be taken into special consideration: The diameter and hardness (HRC) of the wire. The higher both values ​​are, the more difficult it is to cut the wire with a bolt cutter.

However, of course, the material of the bolt cutter head must be considered. This consists mostly of a high-quality tool steel, as Chromium-vanadium steel is known. This steel is extremely tough thanks to the addition of Vandium, which increases the resistance of the blades.

But how is it that bolt cutters can develop such high forces? Expert Jürgen Steinhauer explained to us: 910 millimeter long bolt cutters would have to cut objects with a diameter of seven millimeters

140: 1 mean gear ratio is about twice as large as the gear ratios of the bellcrank system are dynamically changed, so if a powerful craftsman puts the grips together at 750 Newton or more, the end of the cycle will be between the blades When you press a chisel that presses on a workpiece, 15 cars, then there's something really powerful! "

3.3. grip

Bolt cutter with plastic multi-component handles.

To avoid slipping off the handles when cutting with your hands, the grip material used and the grip properties are of particular importance. In most cases The legs of the handles are made of plastic or rubber. Especially in the case of plastic models, so-called multi-component handles have prevailed in the higher price segment. They have a high slip resistance and pleasant properties in terms of grip and working comfort.

Tip: Not only multi-component plastic handles, but also rubber handles usually have sufficient non-slip properties, so you can easily work with them.

4. Questions and answers about bolt cutters

4.1. How much is a bolt cutter?

Bolt Cutters Comparison 2018: 2018

Professionals should definitely invest in high quality bolt cutters. These are usually available for prices between 20 and 70 euros.

A cheap bolt cutter is already available for less than ten euros. However, we advise bolt cutters to buy high-quality products that can usually only be found in a higher price segment. For bolt cutters of well-known companies such as Knipex you can certainly spend sums between 20 and 70 euros.

4.2. How exactly does a bolt cutter work?

The bolt cutter works by means of the so-called knee lever. It makes use of a long lever (handles) and the attached behind the head joint construction to obtain a high force transmission on the last millimeters of the cutting process at low actuation force. A rule of thumb: The stretched the tool from the head to the handle, the greater is the translated manual force when pressing.

Did you know? Actually, the bolt cutter does not cut the material, it blows it up. Due to the effective pressure, the knives penetrate into the material to be separated and leave notches there. During the further closing process, the pressure at these points ultimately becomes so great that the processed object is ultimately burst apart.

4.3. What does Stiftung Warentest say about bolt cutters?

Bolt Cutters Comparison 2018: bolt

The Abus bike lock Ugrip Plus 500 can not be cut with a conventional bolt cutter.

The Stiftung Warentest focuses on the subject of bolt cutters in particular in the context of tests, quick tests and reports on the uncertainty of bicycle locks. For example, bolt cutters in the Bike Lock Test (Edition 05/2015) were among the various tools used to break up bicycle locks.

It was noticeable that there are currently on the market absolutely safe bike locks and most locks are easy to crack. In her issue 04/2013 she even called the much sold spiral cables as "gift ribbons for thieves", because they are particularly easy - u. a. also with the bolt cutter - break open.
