Features and selection of circular saws for metal

The success of work in the construction direction depends on many factors, among which are the experience of the workers and the competent selection of equipment. Teams of professionals who have been building premises for many years can confidently say that finding the right tool is a rather daunting task. In the modern world, this approach is especially relevant, since there are a huge number of different devices on the market designed to perform certain tasks. The device must be of high quality, simple and understandable to use, and also meet the requirements of the operator.

The device is a design based on a special rotating disc. The device can be used to saw wood, steel, ceramic and other surfaces. Also, very often installers use it during concrete work with a foundation, for cutting a reinforcing bar, in the manufacture of porcelain stoneware or when working with solid bricks. Such a tool is popular only at construction sites or in production, since at home there is no need to cut large-sized materials in large quantities. The device should be used very carefully, and before starting work, it must be correctly configured, otherwise even an experienced operator may get injured.

Cutting machines are used for industrial purposes, when it is necessary to quickly and efficiently cut reinforcing rods or boards. The professional tool has a large cutter diameter that can handle a wide variety of objects.

Manufacturing companies also present on the market small-sized versions of the device, created specifically for domestic use. Several stages of protection are provided here for the safety of the operator. The main component of the device is the fixed base of the machine - this ensures a perfect thread. The frame has a closed body - this guarantees the protection of the worker's hands from cutters and waste flying in all directions.

It is also worth noting such important elements of the machine as the robust body and the cutting disc. These designs can be divided into subgroups depending on the purpose and direction of rotation of the cutter:

• vertical appliances;
• horizontal;
• devices capable of cutting at different angles.

In large companies, electric automated machines are used in production, which are distinguished by a high price. There are other options - these are small-sized devices that require the constant presence of an operator. Such models are most common in enterprises. The main design feature is high quality as well as wear resistance. The manufacturers claim that such a device, with constant loads and careful use, will last about 15 years. The unit is capable of processing any surface at high speeds without creating defects or damage.

If we divide all the tools into groups, starting from the variety of the saw itself, then they come with bottom, pendulum and center feed.

• Band-cutting machines. The device differs from its competitors in that, instead of a disc, the main cutting element here is a circular band saw, the material of which is made of a high-strength metal alloy. The belt is a serrated steel surface. Such a tool is very often used in industry, since it can be used to make a narrow cut.

• Disc-cutting machines. They are especially popular in metal surface processing industries and in other areas of activity where you have to deal with metal objects. The device is an assembly with a reliable base and a convenient ergonomic holder. With this device, you can easily cut metal sheets, however, all safety rules should be strictly adhered to.

Circular saws for cutting metal are also subdivided according to the platform. Most often, there are machines equipped with a removable or fixed base made of metal. But any of these devices have reliable fasteners. Each manufacturer gives a guarantee that the cut surface will be securely clamped during work. The main part of the tool are durable cutters of various grades.

• Disc cutting machines with an abrasive wheel. They are designed for cutting ferrous and non-ferrous metals, channel bars, rebar and other surfaces. The leader provides for the ability to cut objects at an acute angle. A distinctive feature of this type of tool is the presence of special clamps that ensure the immobility of the material during work.

• Pendulum cut-off machine. The design differs from other options in the specificity of the cutter movement. The manufacturer provides the ability to adjust the speed of rotation of the disk for various tasks. The device is quite powerful and high productivity can be achieved due to the high speed of the cutter. The unit is durable.

• Tabletop edging machines. They are especially popular in small-scale production and meet all government standards. This technique is distinguished by high productivity for cutting a wide variety of surfaces, regardless of structure and size.

Sellers in construction equipment stores often care only about their own profit and praise the most expensive goods. Few people can honestly admit that the chosen option has some limitations in application or is not suitable for home use. Below are some of the criteria, based on which you can select the desired unit.

• Maximum cutting depth. If a tool is purchased for home use, then 6.5 cm is enough. Industrial representatives of this technique have a cutting depth of more than 20 cm. First of all, it is necessary to start from the type of surface that needs to be cut.
• Automation. A device designed to cut plumbing pipes is unlikely to cope with a rebar. Therefore, when working with a more durable material, the tool will perform at its maximum capacity. Such actions will quickly disable the unit. Experts recommend buying machines with an electrical system that will control the speed of the cutter.

• The start should be smooth. This function will protect both the machine and other tools in the room from voltage surges. However, this option is quite rare. If, nevertheless, a design was purchased without a soft start system, then a separate power line should be connected to it.
• Congestion monitoring. This function is mandatory as it allows you to monitor the load during operation. If an overload is felt, the tool will simply begin to slide off, so that the incisors will not become unusable.
• A kind of incisor. All manufacturers offer two types of cutting discs - dusty and cut-off. If you need to purchase a unit with strong incisors, then you should opt for the first option.

Before purchasing such a unit, you should decide on the tasks that it will perform. If you just plan to cut the plumbing pipes, then there is no point in overpaying for an industrial model. If you have to work with a large number of metal objects, then the power of a household tool may not be enough. To cut thin metal sheets of a few millimeters, you can use miter saws or jigsaws for metal - this can significantly save on the purchase.

People engaged in professional activities are constantly monitoring the emergence of new models of circular saws for metal. Below are the most popular models of the device on the Russian market.

• 2414nb Is a hand held electric saw for metal. The device weighs 16 kg. This machine is small and can work not only in a horizontal position, but also at an acute angle. The manufacturer provides protection against unplanned start-up, an insulated housing and a long wire.
• Makita 2414 NB - a vertical alternative to the above-described unit. The device is stationary and operates on a 220 V network. A distinctive feature of the unit is the ability to cut at a right angle. It has a transparent insert to protect the operator's eyes.
• Another striking representative is the electric Dewalt cutting machine... However, in this model, the functionality is very limited. Tool weight is no more than 20 kg. It is compact and durable.
