Making a choice is never easy. Especially when you need to choose not from two options, but from hundreds. That's when serious difficulties begin, because it is not clear how similar ones differ and why they have such a difference in price.
What will happen if you approach the issue of choosing a circular saw through the sleeves, without understanding the types and parameters? At best, you will purchase an expensive model for professional use, and you will work with it from time to time. And as a result, you will end up with a significant overpayment for design features and additional functions that you do not need. Worse, if the tool you choose is used much more intensively than it can handle. One day the saw will break while working with wood that is too hard, or from using it without interruption, or from pressing too hard. Why? Because all the conditions for the upcoming work were not taken into account in advance and, accordingly, the model was chosen incorrectly. You don't want to be in that situation, do you? Then it’s still better to read the article first and only then make a choice. Let's start with what saws are.
Types of circular saws
The instrument is classified according to several parameters.
Depending on the cutting depth circular saws are divided into:
- small, with a cutting depth of 40 to 46 mm;
- medium, with a cutting depth of 50 to 55 mm;
- large, with a cutting depth of 65 to 70 mm;
- professional, with a cutting depth of 65 to 140 mm.
Depending on the design features There are three types of saws.
- - are large and require a special place or even a room for installation. They are recommended for large volumes of work, for example, in furniture production, where several batches of boards need to be cut daily.
- Desktop- have small dimensions and are easy to transport. However, due to this, their performance is much less than that of stationary ones. Suitable for smaller volumes of work, for example, for building a house or a bath.
- Manual- are used if you need to cut a small number of parts made of soft materials: some types of wood, plastic, etc. A useful acquisition for periodic repair work, so low productivity and low power will not become disadvantages in this matter.
With considering scope of application saws have the following classification.
- Professional- are used in factories and workshops - where a large number of workpieces of various rigidity and dimensions need to be sawed daily. They do not need periodic rest and can work the entire shift without a break.
- household- as the name implies, they are suitable for private use, for example, in home repairs.
The main difference between saws is the resource of the engine and its performance. For professional models, these figures are many times higher.
One of the most important divisions is by type of work performed.
Circular saw for metal
In fact, this type of tool is the most versatile, as it is suitable for working with almost any material: sheet metal, profiles, pipes, as well as wood, plastic, plywood, etc. The cutting disc of such a tool is not abrasive, like other saws, but made of special tool steel of increased strength.
Plunge circular saw
You can’t do without such a tool if you need to make a groove in the surface of a part, for example, cut a hole in a wooden panel for installing a sink. Starting the cut anywhere on the part, not just at the edge, is the main advantage of the plunge-cut saw. In addition, it is widely used when working with multi-layer materials and laminate.
Cordless Circular Saw
As the name implies, it does not operate from a stationary power supply, like previous models, but from its own power source. That is why such saws are widely used in hard-to-reach places, for example, when repairing roofs at high altitude. On average, the operating time of a cordless saw is from 30 to 50 minutes, after which the battery needs to be charged. And this process is already longer - about 4 hours.
Main technical characteristics
So we got to the very essence - to the choice of a circular saw.
Power
The thickness and density of the parts being cut depend on it. It is worth choosing a saw for power very carefully. For example, you have purchased a low-power saw for working with wooden parts. But they did not take into account that the knots are denser than the trunk, and a saw with low power will simply stall during this operation. However, do not forget about the other side: buying a saw that is too powerful for single operations threatens you with wasting money, as well as the work of the tool is almost wasted, since you will not use all its power. For infrequent housework, you should choose a household grade circular saw with a power of about 1000 - 1200 watts.
Disc speed
It is related to the speed of cutting blanks and the ability to work with different materials. The more revolutions the saw can produce, the easier it will be to cope with dense materials, such as wood. In addition, a saw blade with a high blade speed is less likely to jam in the part.
It should be noted that some low power circular saws can have a large number of revolutions, for example,. With a power of 400 watts, this model has a disc speed of 6500 rpm. So a large number of revolutions will not be an obstacle when choosing.
Cutting depth
This feature is directly related from the diameter of the working disk. Accordingly, both of these factors are selected based on the thickness of the part that you have to cut. For clarity: in everyday life, models with a cutting depth of 40 - 45 mm are quite enough. Using them, you can easily master blanks made of plywood, chipboard, fiberboard, etc. To work with boards and other parts with a thickness of 50 - 55 mm, you will need a saw that is more powerful and with a greater cutting depth. Most often, such models are chosen by summer residents for repair and construction outside the city.
Working at an angle
Most models of circular saws can cut parts not only in a straight line, but also at an angle of 45 °. However, at the moment, models are already being produced that are capable of cutting at an angle of up to 60 °. It is also worth paying attention to maximum cutting depth at an angle of 90°. This characteristic indicates how deep the cutting blade can go into the material of the part when the saw is moving perpendicular to the surface of the workpiece. If you have to work mainly with thin products - up to 40 mm thick, then you should choose a circular saw model with the same depth of cut at an angle of 90 ° - 40 mm.
Additional functions
Today, manufacturers equip their models with an additional set of features. Check them out and decide which ones are important to you and which ones you should not pay extra money for.
- sawdust collection- in the design of such saws, a special pipe is provided, to which you can connect a vacuum cleaner or dust collector. Then all the dirt and sawdust that are formed during operation immediately end up in the trash can and do not enter the room.
- laser mark- a clearly calculated trajectory along which the part must be cut. This is a useful feature, as the accuracy and precision of the cut is greatly improved.
- Housing material- most often high-strength plastic, which is used in the manufacture of tools. However, there are professional models with a metal case. Of course, its strength is higher than that of plastic, however, saws weigh an order of magnitude more, which affects the intensity of their work.
- Random start blocking- guarantees the protection of the operator from injury in case of accidental start of the tool.
- Soft start function- provides sawing of the workpiece without sharp cuts of the saw into the material of the part. In addition, a smooth start significantly increases the life of the engine.
Popular models and manufacturers
More than 200 models of various circular saws and more than 20 manufacturers are presented on our website. Consider the models of circular saws, which are especially popular.
A model from a well-known manufacturer that has won the trust of customers not only in Russia, but also in many European countries.
