It is important to match the blade of a circular saw to the material you are cutting. Consider the material you are cutting and its difficulty to determine which blade will work best. We will show you the best blade for each material in the following examples.
Wood:
A general-purpose blade is best for wood cutting. A blade of 10 to 30 cm is best if you plan on cutting harder or thicker woods. A combination blade is recommended for cutting wood with nails.
Hardboard And Plywood:
It is important to consider how many nails there are in plywood or hardboard you plan on cutting. A demolition blade will be needed if there are many nails. A general-purpose blade is better.
Metal:
A demolition blade is a good choice if you plan to cut metal. These blades can cause damage to your saw so it is worth being cautious. We recommend using a metal-cutting knife with a guard.
Cement Board
For cutting cement boards, a demolition blade is your only option. These blades can cause damage to your saw so it is important that you use safety equipment such as gloves and an eye shield.
Masonry:
For cutting bricks and natural stones, a demolition blade is your only choice. If you don’t wear safety equipment, they can cause damage to your saw. It is important that you use these blades with gloves and an eye shield.
Different Size Blades
All circular saw blades look similar at first glance. There are many blade sizes for every diameter of the blade. There are four common blade sizes: 7 inches, 20cm, 25cm, 25cm, and 30cm. There are three types of blades available for each size:
General-purpose Blades:
For cutting wood, the most popular choice is the general-purpose knife. Manufacturers call them heels. It has a combination flat and sharp edges. This reduces friction when sawing through wood. It also results in smooth cuts with low kickback.
7 1/10cm Circular Saw Blades:
A general-purpose blade, as the name implies, is made for cutting most kinds of material. They are medium in thickness with equally spaced teeth throughout the blade’s body. They can be used to cut various materials and have an average finish.
20 Cm Circular Saw Blades
This is the most common size for circular saws. 20 cm blades work best with this blade. This diameter is for a general-purpose blade of medium thickness. Although the spacing of the teeth is different, they don’t leave a smooth finish like a blade with a 30 or 10 cm diameter.
25 Cm Circular Saw Blades
These blades are best suited for use on a circular saw with a length of 25 cm. They have medium-thickness teeth and equally spaced teeth. These teeth have the smoothest finish out of all three general-purpose sizes. However, they are less likely to cut through hard materials.
30cm Circular Saw Blades:
The largest of all three general purpose blade sizes, the 30 cm general-purpose blades work best when used with a circular saw 30 cm in diameter. These blades are stronger than their 8 and 25 cm counterparts. They have thicker bodies with more spaced teeth, which allows them to cut through harder materials such as wood with nails or metal.
Combination Blades:
A combination blade can make many types of cuts, as the name implies. A typical blade has 40 teeth (10%) and is most often used to cut wood with nails. Although it won’t leave a smooth finish like 10 or 30 cm blades, this blade can still cut through hard materials such as plywood and hardboard.
Demolition Blades:
A demolition blade is the thickest and most coarse-grained of all three sizes. These blades have 60 teeth (15%) and are made for cutting through heavy materials such as metal, masonry, and other hard materials. They are more likely to cause damage to a saw. Why would you use one? They can cut through very heavy materials extremely quickly.
