• the operating range of revolutions is 2600-6400 per minute;
• in addition, the device is equipped with a soft start function, it also implements the ability to work with a guide rail;
• when working at an angle of 90 degrees, the tool allows you to create a cut up to a depth of 11 mm.

Choosing a sawing tool is a daunting task for any consumer, be it a professional or a DIYer. Indeed, today many types of equipment from various manufacturers are on sale. In order not to be disappointed in the choice, you need to know which brands deserve attention.

All Makita products are highly reliable, but this is not enough to comfortably complete the task.

It is also necessary to pay attention to other characteristics when choosing, primarily the engine power. It will depend on this whether the saw will be able to create the required cutting depth and how well it will cope with this.

Selection Tips

Which circular saw do you use?

Rechargeable electric

Before buying a circular saw, you should decide on the purpose of its application. The main types of materials involve the use of certain instrument models. If the work is done with an unsuitable device, then it can quickly become unusable.

Expert opinion
Dmitry Levin

Large diameter attachments allow handling thick materials, but also require a powerful motor and a capacious power source. Such units have a higher price and weight. In most cases, for home use, such powerful saws are not required, so you should not overpay for them.

There are three groups of cutting depth devices with corresponding ranges of blade diameters:

• 40-50 mm - this figure is enough for small tasks and processing sheet products.
• 50-65 mm are universal devices for home use, presented in the widest range.
• Over 65 mm - rare models with heavy weight and a capacious power supply. For such attachments, it is preferable to use network devices.

It is better to give preference to tool options with a speed regulator. When working with various types of materials, changing the rotation speed is quite relevant. High-speed models heat the blade a lot and can deform thin products, but provide a smoother cut.

The smoothness of the cut edges is also largely influenced by the number of teeth of a certain shape on the disc.

Battery products are often supplemented with some useful features:

• Constant speed. It allows you to maintain a certain speed indicator when working with heterogeneous arrays. As a result, the saw jams less and produces a smoother, cleaner cut.
• Smooth start. Eliminates the appearance of a jerk when starting work at high speeds, which extends the life of the engine.

• Overload fuse. This function shuts down the motor when excessive load is reached to prevent combustion.
• Engine brake. Ensures the safety of using the unit.

Quality base plates are durable light alloy castings. It will not be superfluous to have a cutting angle regulator in the tool.

The guide bar also contributes to a neat cut. This element is often absent in the instrument set. But you can always purchase a separate universal option.

It is also important to choose a saw with a comfortable handle. For a mobile device, this is often a fundamental criterion for comfortable work.

Additional functionality

When choosing a tool, you should pay attention to the presence of protection against accidental activation. For this, most modern circular saws have a button on the main handle.

For individual instruments, this button can be used to lock the trigger, which makes the equipment safe to operate.

It will be more convenient to replace the disc if the spindle is supplemented with a lever or a button for fixing it. There are also such models in which you do not need to look for a fixation point by scrolling the trigger.

But if your instrument does not have such a lock, then in this case two keys are used.

It is also very important that the tool has an adjustment for the incline of the cut. To create a comfortable working environment at an angle, the operator only needs to change the position of the platform in relation to the top and the disc

Usually an inclination of 30 or 45 degrees is used, although there are also such saw options where you can change the cutting angle up to 55 degrees.

Types and features

Hand tools - the simplest saw unit, compact and powerful (1200-5000 W), with immersion depth of the circle 40-70 mm... For many of these units, the option to change the cutting angle is provided.

Table saw - the mechanism is stationary and motionless, installed on a bed or frame, when sawing wood, the workpiece moves, and not the cutting tool. Such a tool also has a cutting depth of 40-70 mm. It is possible to cut material along or across at different angles.

The stationary circular saw is best suited for private carpenters - the saw blade can cut to a depth of ≤ 140 mm. A cast or welded frame is another difference that such a circular saw has. The cast frame has proven itself when working with large workpieces - the robust construction is additionally reinforced with a separate foundation. The prefabricated frame works in machines with small dimensions, and is designed to work with small workpieces.

The working blade is made of aluminum, steel or cast iron with a slot for a cutting wheel. At home, the table is often made of hardwood - oak, beech, etc. Guides are attached to the table to make it easier to work with sawing.

The plunge cut makes the cut more accurate, since the tool can be positioned almost perfectly on the workpiece before sawing, and then turn on the rotation and lower the blade. The immersion disk allows local work in hard-to-reach places, while, no matter how complex the operation, its accuracy will be observed to the millimeter. Cutting is possible only at an angle 90, its depth is 10-75 mm.

The cordless circular saw operates from a self-contained battery, and is designed for cutting material in places with limited access. The operating time depends on the saw model and battery capacity - 15-50 minutes. Average charging time is 4 hours.

The depth of cut is adjustable to avoid dangerous kickback when the saw head gets jammed. To collect sawdust (to see the cutting line), a branch pipe is provided to which a vacuum cleaner can be connected.

The cutting angle is adjustable from 0 to 45 degrees. To increase the cutting accuracy, you can attach an additional guide bar, to which an adapter is provided in the design.

Users emphasize the build quality (no backlash), light weight (relative to power), and thoughtful design. Many have noticed that the native disc is of excellent quality. Some buyers note the rather weak bearing of the circular saw blade reducer.

Pros:

• powerful;
• compact and easy to use;
• easy access to the brushes for replacement;
• moderate noise level at idle;
• the wire insulation does not harden in the cold.

The device, principle of operation and application of the circular saw

At first glance, the device of a circular saw is as simple as possible - a powerful motor, on the shaft of which a cutting metal disc is put on. In the case of stationary tools, the engine can be located separately and transmit force to the working shaft by a belt through a system of pulleys, but hand tools, which are the vast majority of household tools, are made in one housing.

The complexity of the device is added by the need to use high-quality materials, strict observance of the centering of parts, plus withstanding serious security measures. The saw blade rotates at high speeds, so neglecting any of the above points will at best lead to tool breakage.

As a result, an impressive number of mechanical-electronic protective and blocking devices are added to the engine and the cut-off wheel, the purpose of which is to instantly stop and de-energize the tool if something goes wrong.

The principle of operation of a circular saw is clear from its design - a rotating disc with teeth cuts the board along which the tool itself is pulled. In the case of a stationary saw, everything happens the other way around - the board is pulled through a circle fixed on the bed and divided into two parts.

There is one important note to the use of a circular saw - it is not suitable for curly cutting and is intended to saw boards and other materials only in a straight line. There are models with an additional graduation of the leading sole, which allows the disc to be set not strictly perpendicular to the surface being cut, but at a certain angle, but the saw is also carried out strictly in a straight line

Makita 5704 R

Of the design features, the presence of a solid support platform and a riving knife should be highlighted. The operator has the ability to change the position of the angle adjuster and the cutting depth. If necessary, the shaft can be securely fastened so that the disc can be replaced without risk. This tool is designed to work with discs with a diameter of 170 and 190 mm.

To assess the capabilities of the 5704 R model, you should familiarize yourself with its characteristics in more detail. The tool has a disc bore diameter of 30 mm and weighs 4.6 kg. At work at right angles allows you to make cuts up to 66 mm deep.

When deciding to buy this model, it is necessary to take into account that it does not provide for the possibility of adjusting the speed, and also does not support work with a guide rail and is deprived of a soft start. Although she still has a number of advantages:

• supplied with a 2.5 m cable;
• has a significant cutting depth at an angle of 45 degrees, which is 46 mm.

Makita-branded circular saws stand out from their competitors. If we talk about the 5704 R model, then it primarily ensures safe operation, which is due to the presence of a fitting and a protective casing in it. It also implements the possibility of easy control.

The model is equipped with an ergonomic handle that makes the saw more convenient to operate. Thanks to the dust extraction system, the accumulation of sawdust and shavings is excluded, due to which the operator can see the cutting line and be protected from fine dust.

Given the high demand for Makita circular saws, it is not surprising that most of them have only positive reviews.

Among the features of this tool, buyers pay attention to the impressive power, durable material used as the base of the base plate. The model is equipped with a double-sided spindle, which allows the use of discs of different bore diameters

Many other customers also like the low noise level of the tool, as well as the presence of a riving knife.

Types of circular saws

This power tool can be used to solve various problems: home and roof repairs, the manufacture of products from plastic, wood, etc. The entire variety of circular saws can be represented in the form of three main groups:

• Stationary. This type of power tool is perfect for DIYers looking for maximum productivity. These saws can handle large jobs with ease. However, the operation of such machines is possible only if there is a sufficiently large and specially equipped space.
• Manual. Designed for a small amount of work. They are suitable for processing light-strength timber. It is customary to refer to the group of hand saws medium and mini-devices. They attract buyers with such advantages as mobility, low weight, ease of use. Although they have a small operating power, this allows significant savings in electricity costs.
• Tabletop. Some owners often mistake stationary saws for table saws. However, it is rather difficult to confuse them due to significant structural differences. The table saw is more mobile, but it has less performance. Even the owner of a small workshop will be able to allocate enough space for this power tool.

Also, circular saws are usually classified according to the scope of application:

1. Amateur. They are circular electrical devices with compact dimensions, which are widely used in private workshops. Their main difference is small power indicators, but in most cases they are enough to solve emerging problems.
2. Professional. To ensure comfortable and safe operation, such machines must be reliable, robust and durable. Most often they are used in industries where the equipment used must easily withstand many hours of work day without long interruptions.
