How To Choose Best Concrete Saws

Concrete Saws

Concrete cutting is an operation that is widely used at all stages of construction and repair work. Various equipment for cutting concrete is used depending on the features of the structures, the age of the material and the working conditions. The variety of tools allows you to quickly solve any problem of cutting concrete, including when exact, accurate, curly cuts are required and it is necessary to minimize the amount of dust and construction debris.

Types of tools and characteristics

The necessary efficiency is achieved by the use of diamond cutting technology. High-quality cutting is also carried out by affordable lasers. Rail, mobile, portable and stationary tools are types of equipment in which diamond is cut. This equipment has electric, gasoline, diesel, pneumatic and hydraulic drives.

Concrete Saws

Its working parts have various designs, diameters and types, however, coatings of various resistance include diamonds. Depth of cut, concrete strength and the presence of reinforcement in a particular design determine whether manual equipment will be used or if a more powerful machine is needed. The resistance of the material heats the cutting (drilling) parts, so they need to be cooled with water, air. A crumb of diamonds is attached to the cutting surface of the discs by soldering (for wet cutting) and welding it with a laser to the surface (for dry cutting).

While working with concrete choose only the best concrete saws. A сoncrete ыaws is usually used to form horizontal cuts in concrete (roads, runways, etc.). The depth of cut can be up to 60 cm. The design consists of a supporting frame and a drive unit connected via a belt drive to a cutting tool, which has the function of regulating the depth of cut. The wet cutting technology is implemented by supplying water from the tank to the place of work, but there are modifications without it. The electric cutter can be manual or self-propelled. The latter (it uses a gasoline drive) is much more powerful, it is used in conditions of high humidity and in the absence of electric mains. Self-propelled diesel equipment is the most overall, and is designed for long-term continuous use. The power of the devices and the rotation speed of the diamond discs make it possible to cut both unreinforced and reinforced material.


Wall saws

A wall saw performs precise cutting of concrete walls, blocks in all planes, both in the air and under water. It has a low noise level and high performance. Such a cutter makes a cut to a depth of 0.9 m. Its design is based on a sturdy frame on which a transmission and a segmented cutting disc are mounted. The equipment moves along the guide rail (mounted on the wall) and has a smooth speed controller. The waste material and excess heat are removed from the disk by running water supplied at a speed of 10 l / min. A device can also be installed that draws in and removes used water from the cutting area. Electric models operate from a three-phase network, in powerful equipment they use oil stations connected to hydraulics.

Hand tools

There is equipment that allows you to cut concrete with your own hands. Grinders help cutting in dry and wet conditions, which involves the use of appropriate types and modifications of discs (turbo-diamond, endless, segmented) with a diameter of 0.2 – 0.8 m. Such a tool requires cooling with water (air). For cutting to a depth of more than 0.1 and up to 0.16 meters, an electric, pneumatic or hydraulic cutter – a circular saw – is already required. The cutter can have a gasoline drive, which makes it more powerful, but it creates exhaust fumes. The greatest productivity and durability has hydraulic equipment. With a mass of about 8 kg, she makes cuts up to 26 cm deep. Tool hole preparation is carried out with perforators using a diamond crown. With such powerful tools, they drill holes with a diameter of up to 45 cm with their own hands (carbide crown). Wall fragments can also be cut with a chainsaw on concrete. It will provide a filigree cut of the desired shape. The hand saw has a water-cooled cutter, which is formed by a metal chain with a dusting (diamond). Such a saw is effectively used when working with unreinforced or slightly reinforced material. The drive, providing a depth of cut of seams up to 50 cm, can be with a gasoline engine or powered by an electrical outlet.

Rope cutting

Cutting of large-sized walls, structures is also done with the help of equipment, the active element of which is a rope with evenly distributed segments of diamond grains. Such a tool can cover up to 10 m2 of the area of ​​the future cut. The product includes a power plant, a cutting metal cable, a pulley (creates movement) and exhaust rollers (form a cut form). The unit drive is powered by a three-phase network or can be hydraulic. Before starting work, a hole of the desired diameter is drilled in the structure, a rope is pulled into it. The closed loop of the cable is attached to the pulley. The supplied water frees the working area from waste material and cools the tool.


The task of giving the already installed concrete the right sizes, shapes arises at different stages of construction, repair. Features of the material, its age, density, and the presence of reinforcement require the use of appropriate equipment, the diversity of which allows you to solve any problems.
