What is a circular saw exactly?

A circular saw is a machine for making longitudinal and bevel cuts in a wide variety of materials.  It is equipped with a powerful electric motor that spins a serrated circular blade at high speed.  This turn or revolution is measured in RPM, which stands for “Revolutions Per Minute.” The higher the power, the more revolutions.

Circular saws are widely used in carpentry.  Before working with them, you should take into account the type of material you are using, and adapt the sheet to it accordingly.

What are the main uses of a circular saw?

Circular saws are used to make accurate cuts on materials.  One of their finest abilities is to make cuts at an angle and beveled edges.  They are used to cut materials in construction projects; for instance, cutting door frames.  They are also made to cut tiles.

Why is a circular saw better than a band saw?

There are other types of electric saws with similar functions to the circular ones, such as band saws and jigsaws. That being said, most professionals prefer circular saws.  They also like them for “soft” metals such as aluminium.

Let’s see why:

Why is it sensible to buy a circular saw?

Circular saws have become an indispensable tool in many workshops. They are ideal for professionals and DIY lovers. In addition, they offer a number of advantages like precision, versatility, and the ability to make bevel cuts that you cannot overlook.

Below is a list of advantages and disadvantages:

What types of circular saws are there?

There are different types of circular saws on the market. Generally, we can differentiate between table and portable circular saws. The first ones are anchored to a cutting table, so they are very comfortable, but cannot be moved.  The latter are less powerful, but lighter and easier to handle.

Similarly, you can differentiate between an electric machine with a cable and a circular saw with a battery.  The former needs to be connected to a power outlet, while the latter has a battery.

The advantage of cordless saws is that you can use it without power, like in a workshop or garden.

How to use a circular saw?

Before you start cutting, it is a good idea to draw a cutting line.  Furthermore, the material to be cut must be attached to the table or the cutting surface. On the table saw, you have to slide the material towards the cutting blade.  As mentioned in the manuals, you must follow the cutting line, supporting the saw as you slide it gradually.

What measures must be followed to avoid accidents when using a circular saw?

As always, you should follow the basic safety rules applicable to any job and any power tool. However, a saw is a dangerous tool, so let’s look at some specific safety regulations for the use of circular saws:

  • Never support the piece with your hand.  To push or guide small pieces, use a wooden slat.
  • If the machine stops suddenly, it is best to move away. It is not wise to make adjustments or manual alterations.
  • Before you start cutting, you must rotate the disc manually. With the machine disconnected from the electric grid, check that is has no structural damage or broken teeth.
  • The cuts should be made in an open area. If possible, outside.
  • Wear masks and goggles when we make cuts.
  • Never cut in the wind. Dust and sawdust will land on us; nor should we work in flooded places.

What care does a circular saw require?

Like any precision tool, circular saws require basic care to ensure their proper functioning. Proper maintenance is essential to maximizing its lifespan.  Otherwise, it won’t be long before you have to buy a new one.

When operating with an electric motor, it is crucial to prevent it from getting in contact with water.  It is also important to maintain proper cleaning after each use to avoid dust accumulation.  It is recommended to store the tool in a cool and dry place, away from moisture; if possible, always in your case or toolkit.

Shopping Criteria

If you have read our shopping guide you already know all the basics about circular saws. However, before making your final purchase we recommend you read the following section where we explain the most important factors and criteria you should consider when buying a circular saw.

  • Cutting Speed
  • Brand
  • Cutting Angles
  • Type of Saw
  • Power
  • Intended Use
  • Accessories

Cutting Speed

When it’s time to choose a circular saw, it is important that you select a model with different speeds.  This allows you to work on different materials.  In addition, it will increase the versatility of the tool.  It is imperative that you understand that the maximum speed is determined by engine power.

Generally, modern saws incorporate an electronic cutting speed control system.  This makes it easier for you to change the speed, so you can work more freely.  You can adapt better to different materials you work with. Unfortunately, the cheapest equipment often does not have this function.

Brand

You can opt to buy a machine from a recognized brand or a circular saw without a brand.  Unfortunately, the quality of the machine is often directly linked to the brand, and also to its price.  We strongly recommend that you choose a saw from a reliable brand.

The best brands offer quality products. They also provide better customer service. It is also important to ensure that the manufacturer offers the correct warranty options, a minimum of two years.  This way, you will always be covered in case of the unforeseen or breakdown.

Cutting Angles

The two main cutting angles are called attack and bevel. These vary between 6º (negative) and 35º (positive), plus the simple angle. The criteria for choosing the right angle has to do with the quality, type, and resistance of the material.  It also counts forward speed and the position of the disc against the material.

Type of Saw

Basically, there are two types of saws: bench saws and manual saws.  Table saws are generally more powerful because they have a bigger engine. They are anchored to the cutting table and the operator moves the material to be cut toward the blade. Some models have movable supports to regulate the depth and adjust the cutting angle.

Manual saws are lighter.  They are equipped with protective housing and ergonomic rubber handles that make the job easier.  The blades have protectors on them to prevent accidents. They are not as powerful as the table ones, so they are not great for working on harder materials. Some models incorporate deposits that absorb dust.

Power

Power is a fundamental aspect when it comes to choosing a circular saw.  Keep in mind that to cut materials of greater density, a powerful motor is needed.  Furthermore, the higher the power, the faster the rotation speed reaches the blade.  The usual power levels of these tools are between 1400 W and 1800 W.

If you are a DIY fan, and you are not going to use the saw for elaborate work, a 1400 W power saw will suffice. However, for professional and demanding jobs, it is advisable to buy one of greater power, greater than 1600 W. Do not forget that the higher the power, the more expensive the saw will be.

Intended Use

Depending on the use you intend for your circular saw, you have to choose a suitable model.  You won’t need the same saw for occasional or DIY use as you would for frequent professional jobs.  Similarly, you must take into account the materials that you will cut regularly with the saw.

Accessories

Having certain accessories will allow you to take on specific jobs for which great skill is needed. The cutting guides are indispensable and interesting. With these, you can cut more accurately and keep a straight line effortlessly.  Some models of circular saws have laser cutting guides.

Other useful accessories are the dust absorption tanks. These tanks are connected to a vacuum outlet; they help keep the cutting area clean. Nor can we forget the functions of the automatic stop and the protectors of the saw blade. With these systems, we can avoid accidents in case we place our fingers on the sheet.

Summary

Circular saws are fundamental tools for professionals and DIY lovers. They offer great features and help you make precise cuts, both bevel and angle. They can be used to work on wood, metal, aluminium, plastic, vinyl, and more.

On the other hand, if you plan on buying a circular saw, you should evaluate some criteria, as you have read in the last section of this article.  Materials, spare parts, and safety are key, but so are the battery and price-quality ratio.  Consider all factors before choosing!
