The Ultimate Guide to Choosing and Buying Circular Saw Blades

Selecting the right Circular saw blade is more crucial than the material and brand. Choosing the correct blade can save you time and costs while improving efficiency. With a variety of saw blades available, it can be overwhelming without understanding their differences. We'll delve into the types and parameters of circular saw blades, providing significant assistance in your selection and purchase.

Understanding the Parameters and Performance of Circular Saw Blades

The structure of circular saw blades is complex, composed of various dimensions and components, including diameter, cutting edge, tooth, grind, hook angle, tooth count, dado blades, arbor hole, and blade coating. Let's explore their differences.


The maximum diameter of the circular saw blade, measured in millimeters or inches. Diameter is a critical dimension determining the blade's compatibility with saw machines and cutting materials.


Cutting Edge

The cutting section of the circular saw blade, consisting of teeth and inter-tooth parts. Teeth are the primary part for cutting materials, while inter-tooth parts facilitate chip removal.


The cutting edge of the circular saw blade, comprising tooth tip, tooth bottom, tooth face, and tooth back. The tooth tip is the sharpest part for material cutting, the tooth bottom supports the tooth tip, the tooth face expels chips, and the tooth back prevents tooth wear.



The shape and size of the teeth. Grinding is a crucial process in circular saw blade manufacturing, determining its cutting performance. Common grinding types include straight grind, bevel grind, chamfer grind, etc.

Hook Angle

The angle between the tooth tip and tooth back. A larger hook angle increases cutting force but also enhances wear susceptibility.

Tooth Count

The number of teeth on the blade. More teeth result in faster cutting but may increase vibration.

Types of Circular Saw Blades

Circular saw blades come in various types, with standard circular saw blades being the most common. However, there are many others, including vertical and horizontal cutting blades, continuous rim blades, turbo-rim blades, segmented blades, and grinding blades. Let's delve into these popular blade types.

1. Standard Circular Saw Blades:

The most widely used and versatile, standard circular saw blades are effective for cutting hardwood and wood composite materials. The number of teeth on the blade determines cutting speed, with more teeth providing faster cuts for a smoother finish.

2. Vertical and Horizontal Cutting Blades:

Designed for tearing through wood grain, these blades typically have 16-40 teeth. Deep gullets effectively remove material. Horizontal cutting blades are designed for cross-cutting wood grain, with lengths ranging from 40 to 80 teeth, providing cleaner and neater cuts.

3. Continuous Rim Blades:

The edge of continuous rim blades is made with diamond, suitable for cutting hard materials like tiles. The embedded diamonds can cut through materials, leaving a clean surface finish.

4. Turbo-Rim Blades:

Similar to continuous rim blades, turbo-rim blades have a diamond-edged serrated rim. They are used for cutting materials like concrete, but the surface finish may not be as refined. Generally used for dry cutting.

5. Segmented Blades:

Segmented blades have a similar edge to regular blades, with teeth separated by gaps. They exhibit robust cutting capabilities, high efficiency, and can handle most stones and concrete. However, their cutting strength results in a rough surface finish.


6. Grinding Blades:

Designed for cutting hard materials like stone and concrete, grinding blades use abrasives such as aluminum oxide and silicon carbide.

Key Consideration: 

In different applications, improper usage can lead to challenges such as difficult cutting, faster blade deterioration, unsightly cuts, and reduced efficiency. Therefore, it is crucial to choose the right circular saw blade to facilitate successful operations.


The aforementioned details cover various types of circular saw blades, each unique in its cutting efficiency and applicable materials. Selection should be based on the specific type of material to be cut. Whether it's a standard circular saw blade, rip and crosscut blades, continuous rim blades, turbo rim blades, segmented blades, or grinding blades, choosing the right circular saw blade can significantly enhance cutting efficiency.
