Rating of the best circular saw blades for 2020

The homeowner's arsenal must contain equipment from only the best manufacturers. This review contains information that will help you decide and tell you how to correctly choose an inexpensive but high-quality cutter.

A circular saw is an indispensable tool for installation work. With its powerful motor and fast rotating disc blade, it cuts heavy-duty building materials.

The advantages and disadvantages of circular saws

Perhaps only a jigsaw can compete in the versatility of the tasks performed with a circular. For tough jobs such as trimming lumber or oversized plywood panels, a turntable or bed comes in handy.

Circular, hand saw has two limitations:

• Inability to cut to great depth. For popular models, the cut does not exceed 6.25 cm.
• If you want a curved flank, you'll have to choose a jigsaw.

Despite some drawbacks, a disc cutter must be in the arsenal of a professional carpenter. This is the only tool that is equally good for both concrete and wooden structures in the country, and most importantly, it will do all the work in the shortest possible time.

The circular saw is similar to a high-speed table saw, and the ability to install it permanently actually makes the functionality of these tools the same. There is one thing that the tool does better than any other so called "plunge". This is an advanced yet simple technique in which the blade "bites" into the material from above to make internal cuts without edging.

Parts and characteristics of circular saws

The disc cutter is ergonomic, with a D-shaped handle with a smooth trigger on the top, a holder on the side for a more confident grip. Safe use is guaranteed by a protective cover. The up and down blade adjusts the cutting depth.

There are two main types of engine:

• for a standard (side) saw, the movement is provided by the shaft;
• the worm gear design gives the mechanism more torque, is effective when facing with a broach, and is able to maintain constant rpm under load.

For domestic use, a standard one is better, because it is small, more maneuverable, easier to use than a worm gear.

Size matters

Tool dimensions depend on disc size. The most common diameter (18.5 cm) cuts to a depth of about 6 cm, mini saws can use 8 cm blades. In all cases, the depth of cut is less than half the diameter because the cutter rotates on a mandrel in the center of the blade.

There are larger instruments - 25.5 cm.and less common - 41.5 cm, called a ray saw. This is a professional-grade equipment for loggers. Note that smaller blades will fit on larger saws, but cannot use a 25.5 cm blade on a 20 cm cutter.

Small tools are good for thin materials such as plywood; finishing, paneling or occasional woodworking, but for other jobs (including sawing masonry), standard 7 ”equipment is the best choice.

Types of attachments

To determine the criteria for choosing equipment, you need to clearly understand the essence of the upcoming work, for each there is a suitable knife:

• A universal option for wood is a carbide-tipped combination blade (usually 24). It quickly processes lumber, plywood, as well as metal and plastic.
• A 40-flute disc is used for fine wood finishing and cuts are cleaner than with a combo knife.
• Abrasive wheels are good for masonry, metal, ceramic tiles. They wear out quickly, so buy a spare if you're planning a big project.
• The ideal option for a stone is a diamond bit. It is expensive but lasts much longer and produces cleaner cuts than abrasive discs.

Cordless saws

Like most electric tools, circulars are: wired (mains), as well as battery-powered.

The trade-off on which model is better to buy is very simple: the network offers constant, high power. Rechargeable - convenience, there is no extension cord to reel, and the need to look for an outlet will be a thing of the past. If you need to make multiple cuts in a remote location with no power, a cordless tool is your only option.

With a conventional torch, the power rating can range from 5 to 15 amps. The larger it is, the cleaner the cuts, and the more durable the blade.

Battery strength is calculated in volts. The standard value is 18 W. In addition to voltage, ampere hours (A / h) are often indicated, which determine the capacity of the battery (how quickly it will discharge), ranging from 5-9. Note that some manufacturers offer additional batteries with higher voltage and capacity.

As for the design, it is rather arbitrary. In addition, the 5007N has tapered stops, so you can handle various angles without much effort. The 15 amp motor develops speeds of up to 5800 rpm, guaranteeing durability and efficiency. Makita models have long gained popularity among professionals and amateurs of woodworking.

Accuracy is increased thanks to two built-in LED lights that are designed to calibrate the cut line. Tilt work, with some stops, is possible up to 56 ⁰.

On the downside, the biggest one is the lack of dust control. In other words, many people complain about getting sawdust in their face, which is not a very pleasant experience.

The advantages are many, the most obvious being the build quality. The case is made of durable and reliable materials, so you don't have to worry about sudden malfunctions. In addition, the presence of tapered stops, LED indicators, smooth running, also adds pluses.

1. Makita 5477NB

Another "Makita" on our list is the focus of compactness, power. The 5477NB is similar to the 5007N with some notable differences. The first is the design, the functionality has remained more or less the same. When it comes to build quality, Makita never ceases to amaze its customers with high quality and affordable prices.

The 15A motor propels the blade to 4500 rpm using an innovative technology called "compressed winding". This is a fairly simple yet effective principle. It allows the machine to do quality work while providing high productivity. The auxiliary gear consists of hypoid gears (a type of helical gear train), which are known for their durability, which is very important especially for professionals. Service life is one of the main advantages of the 5477NB.

The unit requires constant lubrication, the application of which can be difficult, but thanks to the oil bath technology, Makita is always ready for work. The levers on the block are rubberized, on the other hand, the handle is not cushioned, which can be considered a disadvantage and affects if the machine vibrates strongly. Fortunately, gloves can help solve this problem.

There are not so many disadvantages, the most obvious is the lack of protection from sawdust. These problems, however, are present in most manufacturers.

The big advantage of the 5477NB is the weight, which is 3kg. The unit is lightweight, easy to use. Great price - one of the most affordable circular saws in this category.
