Cut Cleanly Through Wood With the Best Circular Saw Blades

What is a Circular Saw Blade?

A circular saw blade is a particular type of blade that works well with circular saws and is mainly designed to easily cut through different materials. The materials that you can cut with circular saw blades include wood, engineered wood, plastic, ferrous and non-ferrous metals, etc. Different types of circular saw blades vary according to the material they can cut through.

Why Do You Need a Circular Saw Blade?

A circular saw blade is a highly efficient accessory that enables you to cut through various materials smoothly and without leaving any rough edges or splinters. The best part of this blade is that you can use it to cut through the material whenever it is in motion, and you don’t have to worry about a return stroke, as is the case with some other types of power saws.

Circular saw blades are reinforced and strengthened to provide the smooth and optimum performance that you experience from your circular saw. Once the blade inside your saw becomes warped or worn out, you can replace it with a similar one to ensure that you keep getting precise and clean cuts every time you use it. You should consider whether or not you want a mini circular saw or a full-sized one depending on the cuts you want.

Circular saw blades are specially designed to withstand the heat generated by the motor, as well as the friction created when it comes into contact with the material. Most of the other blades often get overheated and warped, but this isn’t something you experience with the circular saw blade.  Circular saw blades also facilitate making angled cuts, bevel cuts and rip cuts as well. This makes it an overall useful accessory to have.

Things To Consider Before Choosing a Circular Saw Blade

Before you go about choosing a circular saw blade to replace your existing one, make sure that you have taken all the factors into account, so that you end up with the right product in your cart. Let’s have a look at the various factors that come into play when you are choosing a powerful saw blade.

Number of teeth

Circular saw blades come with numerous teeth counts, ranging from 14 to 120 teeth. The number of teeth a circular saw blade has played a major role in your choice of one. Blades that have more teeth tend to provide a cleaner and smoother cut, whereas those with fewer teeth would have a rougher finish. Usually, a 24-tooth circular saw blade, is preferred by many people for metal cutting, especially if they have to cross-cut lumber and sheet materials. 

The 24-tooth blade is good enough for you if the diameter is 7¼”. However, as the diameter increases, you should also consider looking for circular saw blades with more teeth.

Hook

The hook refers to the position at which the teeth of the circular saw blade come in contact with the material. Also known as the rake angle, it determines how fast and smooth the cut will be, as well as how quickly the waste material will be removed. If the blade has a positive rake angle, it performs a climb cut and pulls the material in. This can be harmful if you are dealing with a harder material like metal.

On the other hand, a negative rake angle has smoother performance and doesn’t pull the material towards itself. Although this is much safer, it is rather slow and removes less waste from the workpiece.

Kerf

Kerf is another important factor that you must consider while choosing the best circular saw blade, and it refers to the thickness of the tooth, which can also be called the cut width. This also means that the thinner the kerf would be, the smoother and more refined the cutting performance would be. However, thinner kerfs are also prone to vibration or wobbling, which means that they may not cut hardwood precisely.

Type

The type of circular saw blade that you use for your woodworking or other projects also matters when you are exploring different options. This also impacts the performance you get out of your circular saw. The most common type is the standard circular saw blade, which is used to cut wood or composite materials. The speed and finish of the cut are determined by the number of teeth it has.

Similarly, you can also find rip-cut circular saw blades, which have fewer teeth and work more aggressively towards cutting through wood. Crosscut blades have around 40 and 80 teeth and are suitable for clean cutting. 

Apart from this, you can also buy continuous rim blades, which are also known as diamond blades and are used on tiles and ceramic materials. On the other hand, turbo-rim blades are also diamond blades, but their rim is specially designed to cut through brick and concrete. A diamond blade is considered appropriate for cutting porcelain tiles. Apart from these, you can also find segmented blades, abrasive blades, stacked blades, and many others for metal cutting. 

You can choose the type you want according to the material that you need to cut, and the number of teeth will determine how smooth or rough the cut will be. Make sure to factor this in while choosing the best circular saw blade for your projects. Considering the wide range of table saws available, selecting the correct blade for smooth cuts like metal cutting can be quite daunting.
