Rating of the best gas and electric cutters in 2020

In the process of construction work, one has to deal with the need to cut materials of special strength, for example, asphalt, reinforced concrete, etc. Indispensable equipment in this case is gas cutters and electric cutters. The article will help you choose the right tool, for the convenience of the reader, it is divided into the corresponding main sections in which you get acquainted with gasoline and electric cutters.

Description of gas cutters

The gas cutter is a self-contained and portable disc cutter equipped with a dedicated, high-speed, sharp-edged blade. It differs from the circular saw, which is designed for processing wood and other similar materials, in the ability to cut hard and tough materials like stone, concrete, metal and more.

All cutters with high power gasoline engines. The torque of these motors is sufficient to drive large disc diameters, which allows for faster cutting and processing of certain materials.

Such construction tools are often used when concrete, brick and other metals need to be cut. Of course, the thickness that can be cut depends on the technical characteristics of the gasoline cutters.

Using this equipment, it is easy to cut any structure, such as brick. In addition, such a unit is indispensable if it is necessary to make a slitting or to make a groove.

But this is not the main advantage. The primary advantage of this device is its autonomy, it can be easily used in any place, without forgetting to fill the gas tank. Despite the rather high price, this construction tool is readily available even in times of economic instability, and today it is very popular, more and more consumers have begun to buy this construction equipment for home use. Such a gasoline cutter does not lag behind in its functionality more expensive models that can reproduce the same functionality. You can talk for hours about the advantages of using this construction tool, so it is best to evaluate all the advantages in practice.

Design features of gas cutters

The gasoline cutter includes:

1. Powerful engine. The tool must have enough “strength” to cut hard materials. In addition, the engine must have high reliability and durability because it will face very difficult tasks.
2. Cutting disc.As we said, the trimming machine does its job with a belt-driven metal disc. The belt is covered with a robust housing for operator safety and to prevent damage during operation. The disc is also specially shielded to propel material particles so that shadows fall on the operator. Discs can be of different diameters (the most common 350 and 400 mm) and types (abrasive for metal, steel, diamond - for concrete, brick, stone, granite).
3. Special air purification system. During operation, the unit can raise a lot of dust, which is dangerous both for a person and for the gas cutter itself, therefore both need special protection. The problem of protecting the operator from the harmful effects of dust is solved by putting on an aspirator, and protecting the engine from harmful particles is possible using a multi-stage air cleaning system. It includes centrifugal cleaning as well as various large area air filters.
4. Lever. Since the gasoline cutter is a rather heavy tool, so much attention is paid to balancing and the convenience of the handle position (at a distance approximately equal to the shoulder width).
5. Progressive vibration isolation system. The powerful engine at high rpm generates significant vibration, which causes severe discomfort during prolonged operation. Therefore, gasoline cutters are equipped with special shock absorbers and a soft grip coating to dampen vibrations and provide a non-slip grip.

Criteria for choosing a gas cutter

The choice depends on:

• The material that the tool must cut: metal, concrete, or both. Less powerful devices will handle metal with less resistance than concrete or stone. If you need to cut them, select the high power models from 5hp.
• Possibility of turning the protective disc cover. To balance the instrument, the blade is closer to the center with the shroud facing out so you can work close to a wall or other objects.
• Cutting type: wet or dry. Wet cutting has less dust, which means less clogged tool parts. In addition, the cutting disc is cooled efficiently and wear is reduced. With regard to dry cutting, it is better to follow this rule when performing work to protect the blade: 40 seconds of cutting - 15 seconds off.
• Brenda. When choosing a tool, an important criterion is the popularity and popularity of the brand and its reputation, which consists of factors such as quality, durability, reliability, safety, ease of use, availability of spare parts and service.

Description of electric cutters

Electric cutters are tools that have high parameters such as quality, practicality, versatility and safety. They are designed for cutting heavier, harder materials. For example, concrete, stone or asphalt. With the sharp blades of the disc, this type of work will be done as efficiently and productively as possible with minimal cost and effort.

Electric cutters are equipped with special deep cutting technology. Thus, modern electric cutters allow you to work at a depth of about 400 mm with low costs during the operation of the tool. Work with this unit can be carried out both inside and outside. Electric cutters are also great for small jobs.

Most electric cutters today come with induction motors. Their power drives are powerful. Therefore, a high speed of rotation of the spindles is created. And the chucks, in turn, rotate the diamond discs with a high torque. With this design, you can cut stones, bricks, cement and other fairly hard materials.

The electric cutter is an environmentally friendly device.This allows you to use the power tool in small rooms with poor air ventilation. An additional advantage is the absence of a strong noise level during the operation of the equipment. The noise that the electric cutter emits during operation is not strong enough, in addition, there will be no unpleasant smell and strong dust during cutting.

Only one power source is needed to use the electric cutter. It is portable and lightweight. The electric cutter has fairly simple instructions and operating guides. Due to the lack of fuel, they do not emit harmful emissions.

Features of the design of electric cutters

Since the cutter is electric, you will need to run electricity in your workplace. The outlet is not always nearby, in such cases diesel generators or the like can be used. It is worth noting that, despite the fact that electric cutters are less powerful than its gasoline counterparts, an irrefutable advantage is the ability to work inside buildings and premises, that is, it is possible to use a construction tool for finishing and other interior work. This equipment is unique for pavement processing - to cut concrete and granite, as well as repair cracks on hard surfaces. It is also great for cutting pipes into trenches.

Electric cutters are indispensable for treating floors, walls or windows. Reducing the coolant supply greatly reduces the risk of failure or blockage of the rotating disc. Different models may have the ability to spray water directly onto the disc. The volume of water is sufficient to eliminate dust and nothing more. Some units are equipped with an anti-vibration system. Thanks to this, the load on the human body is significantly reduced, since electric cutters vibrate very strongly during operation. When determining with the selection of the most suitable equipment, it is necessary to take into account the presence (or absence) of the following modules: overload protection and current limitation systems, changes in rotation speed.

With electric cutters, the protective case is very easy and convenient to open for easy blade change. Most of the models have a bevel gear of the optimal size, which reduces noise level, reduces power losses and ensures high reliability of the electric cutter. The choice of the design of electric cutters also depends on the material with which you have to work: metal, stone or concrete.

Criteria for choosing electric cutters

When choosing a cutter with an electric drive, you need to pay special attention to the main selection criteria:

• The maximum circle diameter used for a particular model. This affects the depth of cut and ease of use.
• Unit power that does not really matter. Equipment of this kind has optimal parameters to work.
• There are models of devices with their own methods of torque transmission. It depends on the composition of the concrete solution. In this case, the model is chosen depending on the preferences of the master.
• On the location of the hand tool: on the body or trolley. At the same time, a concrete electric cutter has various technical characteristics and performs a certain type of work.

In addition to the above requirements, when choosing an electric cutter, additional selection criteria should be considered:

• When buying an electric cutter, you need to take advantage of the offer of additional guarantees, despite the increase in the final cost. With a long and constant use of the power tool, this will be additional insurance, which will be useful help to avoid tangible costs when performing service repairs.
• When buying a tool, you should inquire about the availability of discs and spare parts, wear of parts and their availability.Immediately you need to purchase additional discs and graphite brushes for your electric cutter.
• The specifications written on the packaging may be incorrect.
