Circular saws, also known as circular saws (capaciously nicknamed “mafel” in Western Europe after the plant in Baden-Württemberg), are an integral part of any woodworking specialist. Small or large, handheld or bench-top, they are all ready to cut plywood, trim boards or shorten floorboards in a precise straight cut. They can easily handle the bench supports in your gazebo and shorten the kitchen countertop to the required size. The main thing is only to choose the right saw blade. Look for best 8 table saw blade.
In this article, you will find short overviews of the best circular saw blades on the market (we made a selection based on saw characteristics, tests performed and user feedback). We will also advise you on how to choose a circular and what to look for when buying it. Beginners will also appreciate a description of the basic disks and how to properly operate them.
How to choose a circular saw
When choosing a circular saw, the following parameters should be considered:
- Engine power. An important parameter that determines the depth of cut, productivity, and blade speed. Generally, the higher the value (expressed in watts), the deeper the cut we can make. Typically, the wattage is in the 1000-1700W range. Of course, the performance of a circular saw is influenced by several factors besides power: the type of engine, the build quality, and the wear resistance of the materials used. There are also cordless circular saws with different engine powers. However, keep in mind that the use of such a saw is limited. The battery must be recharged after 25-30 long cuts. But occasionally there are situations in which the cordless tool is indispensable (for example, in hard-to-reach places). When buying a model with higher electrical power consumption, it is important to have an inrush current limiter that ensures a smooth start of the machine without voltage surges in the network.
- Tool weight. This is an important comparative parameter that largely determines the ease of use of the tool (which significantly affects the ease of cutting). For most models, the weight ranges from 4 to 6 kilograms. More powerful models weigh about 7 kg. As a rule, the better and more powerful the saw, the greater its weight.
- Cutting speed. The higher the power, the deeper the cut. But in the cutting process, it’s not just about what the saw cuts, but how it does it. Cutting cleanliness depends not only on power but also on cutting speed. This is determined by how many revolutions the saw blade can make per minute. The higher the rotational speed, the higher the cutting speed, and the better the cut quality. For ordinary saws, this is about 3000 rpm. For professional models, the speed can exceed 5000 rpm.
- Maximum disc diameter. Pay attention to this parameter. It determines how deep your tool can sink when cutting. You can find circular saw blades on the market with a cutting blade diameter of 165 to 355 mm. As a rule, the depth of cut (cross-section) does not exceed 55 mm, but professional saws can cut 68 mm or more (some models up to 130 mm, which is required for deep cuts on sloped surfaces). The size of the disc determines the maximum cutting depth, therefore, this parameter depends on the diameter of the blade and cannot be increased in any way.
- Product materials. They also tell a lot about the tool. In the hobby class, you have to rely on plastic construction – these circular saws are lightweight but less suitable for frequent use. Professional circular saws are twice as heavy. The blade protectors are made of aluminum alloy, so they are stronger, larger, and designed for long-term use. Individual structural elements provide a protective structure and create a visual design, but connections between individual parts (welds, threaded joints) are also an integral part.
- Transmission. The above parameters are really important when choosing a circular saw, but you must also take into account what material the “box” is made of. The metal transmission will last longer. Lower vibration is also a plus. The disadvantage is that models with such a transmission are disproportionately more expensive (an amateur saw for € 100-200 will probably not have it).
- Guide rail. Believe it or not, the guide rail is one of the most important components of a circular saw. This is because it is this part that is most often regulated, moved, and fixed. It is important to keep this process as simple as possible. There are also special saws that can drive along the rail, which can be fixed to the material, and when the saw moves you get a perfectly straight cut. In addition, it is known in advance exactly where it will be located. This is the biggest difference from the classic ruler, which is relatively short and not as accurate.
- Other features. Circular saws, especially those of a high class, are distinguished by a number of practical functions that provide more reliable and comfortable work. Look out for features like speed control, overheat protection, or the ability to lock when changing blades. For more comfort, you can connect a hose from a vacuum cleaner or other suction device. Models with larger disc diameters (for example, 270 to 355 mm) can be equipped with a sliding sleeve that can protect the motor from the disc seizing in the material. This stops the blade, but the rotor continues to rotate. This prevents the wind from burning.
- Brand. If you want a quality tool, focus on brand reputation. It is from well-established and trusted manufacturers that you can expect the exact level of performance you are looking for. The advantage is the good availability of spare parts and the good customer service that these brands offer. Circular saws from brands such as Ryobi, Extol, Einhell, Interskol, Zubr are offered for domestic use, which can be purchased for only a few tens of euros. Quality circular saw blades with more durability can be found from brands such as Makita, Bosch, and DeWalt. These manufacturers offer powerful, reliable, and popular devices. Professional circular saws are the products of renowned brands such as Metallkraft, Husqvarna, Mafell, or Festool, as well as top models of the Bosch and Makita models. If you are serious about buying a handheld circular saw, first decide how often you plan to cut with it, taking into account the additional features and capabilities that can make your job easier, and then decide on the right brand.
