How to choose a gasoline cutter by characteristics

The handheld chainsaw is a versatile and powerful tool designed for cutting a variety of tough materials, such as concrete and metal. It is powered by an internal combustion engine, making it completely autonomous. The cutting process is typically performed using a high-speed rotating disk, although some models feature a chain. Chainsaws are available in various models for different applications, including home use, professional use, and semi-professional use. To help you make the best choice, let’s explore the different types of chainsaws in more detail.

Construction of a chain saw

• The internal combustion engine (ICE) is a crucial component.
• The fuel tank is another important part.
• The working attachment, such as a disk for cutting materials, is required.
• Both front and rear handles are necessary for proper operation.
• The starter is responsible for initiating the engine.
• A housing is used to protect the engine and other components.
• The carburetor is responsible for mixing fuel and air.
• A throttle button regulates the speed of the engine.
• An air cleaning system, consisting of filters, helps maintain clean air intake.
• The ignition system is responsible for igniting the fuel-air mixture.
• A protective casing is used to safeguard the engine and other parts.
• A throttle plate controls the airflow into the engine.

The tool is primarily equipped with 2-stroke engines. These engines are powered by a fuel mixture of gasoline and oil in a specific ratio. The power is transferred from the engine to the disk via a belt.

The tool also features a multi-stage air purification system, which prevents dust particles from entering the carburetor and cylinder. Some models are also equipped with a water cooling system for the cutting element. This system not only prevents dust formation but also prevents the disk from overheating, allowing for longer wear and a longer lifespan. The water supply for the cutting zone comes from a separate tank.

For modifications weighing over 15 kg, carts are provided to make transportation easier. Additionally, certain models can be remotely controlled. Moreover, there are models with legs that ensure stable installation of the tool during cutting.

The chain cutter’s working attachments can have a diameter of 30-40 cm. The cutting disks can be either diamond-tipped or abrasive. The first type of working tips is made of steel and coated with diamond spray, which enhances the disk’s resistance to wear.

Utilizing a high-quality cutting nozzle can reduce the strain on the engine.

A gas cutter for welders refers to a separate apparatus that includes a fuel tank, pump, torch, and oxygen and gasoline hoses. The gas torch is specifically used for working with metal workpieces and structures.

Scope of use of the tool

Gasoline cutters are versatile tools that are not limited to cutting concrete or metal. They can also be used for sawing various other solid materials including:

• stone;
• asphalt;
• brick;
• composite boards;
• combined materials, such as reinforced concrete pipes;
• cinder blocks and similar materials.

The tool is commonly utilized by construction workers, including road builders, for a variety of repair and construction tasks, such as:

• dismantling various structures;
• cutting openings in walls or partitions;
• cutting reinforced concrete or metal pipes or beams;
• installing curbs and sidewalk tiles;
• drilling partition walls for electrical cable wiring;
• repairing railroad lines and road pavement.

These techniques are commonly used for similar tasks at home.

Furthermore, fire and rescue workers also utilize such gasoline-powered devices in addition to builders.

Chain saws have a major advantage over electric angle grinders (Bulgarian machines) and other types of specialized saws as they do not rely on external power sources. This autonomy makes them highly desirable among cottage owners.

Types of chainsaws for metal and concrete

There are three categories of chain saws, which are determined by the properties of the material they are used on:

• metal chain saws;
• concrete chain saws;
• universal models of chain saws.

The cutting tool for metal has a maximum power of 4200 watts, while the equipment for working with concrete structures has a higher power and a faster disk speed.

Concrete sawing equipment is produced with a power of over 4.2 kW and an average disk speed of 4.7 thousand revolutions per minute. These performance characteristics are necessary to prevent the working nozzle from getting stuck in the cut monolith.

Universal modifications have higher power and speed, allowing for cutting different materials.

Specialized models of equipment are also available for sale.

1. A shtroborez (furrow cutter) is a tool that runs on gasoline and is equipped with two parallel disks. Its main purpose is to create grooves in the walls, floor, and ceiling for the installation of electrical wiring and pipes. These ribbed cutters are commonly used by electricians and plumbers.
2. A rail cutter is a specialized equipment used by railway installers for cutting rails. It is equipped with special attachments that allow it to be securely fixed onto the rails, thereby increasing the depth of the cut.
3. A chain cutter is a tool that resembles a gasoline saw in appearance. It is designed to cut through both stone and metal, thanks to the presence of a diamond chain.
4. Chromed chainsaws (their cutting elements are partially covered by a cover coated with chrome, which can be seen in the dark) are utilized by rescuers and emergency workers.

There are specialized attachments available for chainsaws that can be installed to transform them into a chain saw.

Gasoline-powered tools used for processing various materials are classified into the following categories based on their functional capabilities:

• Domestic chainsaws, designed to be used for approximately one hour per day;
• Semi-professional chainsaws, with a working lifespan of around eight hours per day;
• Professional chainsaws, capable of being used for over ten hours per day.

There are two types of gasoline cutters: dry and wet models. The dry model uses air cooling for its disk, which means it needs to take periodic breaks during operation. On the other hand, the wet cutting model uses a water cooler, allowing it to work continuously without the need for rest.

Basic and additional criteria for selecting a tool

When selecting a gasoline-powered internal combustion engine torch, it is important to consider its key technical and operational parameters:

• Power: This factor greatly influences the productivity of the gasoline-powered tool.
