A Circular saw is a multifunctional tool that can be used for cutting different materials depending on the blades. You have to choose the blades as per your nature of work. What materials are you cutting and what kind of cuts do you need to perform with a circular saw? That’s what really matters!
There are varieties of circular saw blades available. Each and every type carries its specialty to a specific material while some are considered to be versatile but they have flaws.
It is advised to woodworkers, especially to the beginners and hobbyists, that never choose multipurpose blades as they are not considered best for newbies and might not last for long, always go for blades that have specialty to the material you are cutting with the circular saw.

11 Types of Circular Saw Blades
Enough with the elaborations! Let’s get back to the topic: what are the circular saw blade types and their uses?
Standard Circular Saw Blades
Blades with teeth are the most used blades which you may find in daily life as the experienced persons and the beginners both groups of woodworkers used them quite often.
Blades with fewer teeth cut the materials very fast on the other hand blades having more teeth provide a fine finish to the job. More blade teeth mean that a single tooth cuts less amount of wood.
1. Ripping Blades
These blades have fewer teeth, usually somewhere b/w 24 to 30.
This number may change with the diameter of the blade as 10 inches blades have 40 to 50 teeth. The gap between teeth has been extended a bit to rip across the grain faster without grinding it. These blades are used to rip hardwood materials and keep them clean too.
2. Combination Blades
These are multipurpose blades used to cut with the grain or across the grain. Having combinations of five teeth divided by throttles, which removes the residuals from woods. These blades are mostly used to cut the hardwoods, softwoods, and plywood.
3. Plywood and Sheet Blades
Mostly used to cut thin materials as they are not that strong to bear the roughness of cutting instruments, for this sake a special blade is designed to cut these materials smoothly. It can also be used for other sheet materials like plastic and fibers. These blades have larger teeth numbers, 100 or more sometimes.
4. Cross-Cutting Blades
These blades are used to cut across the wood grain for example dividing long chips board into two parts without losing the cleanliness of edges. This type of blade has many teeth (48 or more) a small gap is maintained between every tooth that keeps the wood edges neat and clean and finishes the job very well.
5. Hollow Ground Blades
The healthiest member of the blade family. Its composition is slightly different from other blade types. This blade carries a thicker body profile as compared to its teeth, which really keeps the binding away and the blade goes through the material quite smoothly.
6. Thin Kerf Saw Blades
This blade comes with carbide 3/32 inches wider teeth. This thinness keeps the wood intact and cuts it accurately. These blades create less mess around the workspace and wastage of material is also limited.
Thin kerf saw blades help out underpowered saws because every single tooth of the blade takes smaller wood bites eventually reduces the motor work.
7. Segmented Blades
These blades have diamond edges but their rim is divided by large gullets like ground hollowed blades. The segments roughly cut the materials. It is used quite often whenever speed is more important than a cleaner finish. These blades are divided into two categories one of them works for dry cutting while the other is prepared for wet cuttings only. It has the cutting ability for hard materials like concrete and ceramics.
Unconventional Circular Saw Blades
Mentioned above blades are multi-functional blades. They can cut either material like wood, plastic, and other light metal sheets. Choose your desired blade wisely by understanding the nature of your work and also make an assessment of your circular saw working capabilities. Further in this article, we will be discussing the toothless blades which are prepared for specific materials like glass, heavy metal strips, and ceramics tiles
8. Abrasive Blades
These are rough blades made of aluminum oxide. Uses friction to cut heavy metals like steel and iron. Specifically used in a circular saw and frequently used in grinding machines, abrasive blades present high power and destructive behavior to the heavy metals
9. Turbo Rim Blades
Quite similar to the abrasive blades but have a little difference of composure, that these blades have notched rims. It is used to cut hard materials like bricks and ceramics tiles. Some of them work for dry cuttings only and some are suitable for both dry and wet cuttings. Turbo rim blades do not provide cleaner finishes but these blades are more aggressive as compared to abrasive ones.
10. Continuous Rim Blades
These blades are also named diamond blades. Prepared to work on materials like glass and ceramic tiles, diamond tips are placed on the continuous rim blade edges which go through the materials quite smoothly and provide the cleanest finish among all other family members.
11. Stacked Dado Blades
These are sets of blades that include two saw blade types like chippers and shims, frequently used for making grooves into the wooden pieces of several dimensions. These blades are designed for table saws only.
The user’s benefit relies on the blade and circular saw. Everything cannot work properly as some circular saw are not comfortable with certain types of blades, even if all of the things are going fine there is a minimal chance of loss or accident.
Considering safety top priority, users should take care as a whole which means all the elements should be looked after properly according to the working natures for the sake of work efficiency and protection combined.
