What is the blade diameter for products within Jigsaw Blade?

Jigsaw blades come in various diameters as they are an electric saw accessory used to cut different materials. The diameter of the blades used to cut different materials also varies. When selecting a jigsaw blade, it is important to understand the uses and differences between different blade diameters. This article mainly introduces the diameter of this type of blade and the differences in various materials, such as carbon steel and high-speed steel.

1. What are the blade diameters available?

Jigsaw blade diameters typically range from 1 inch (25 millimeters) to 4 inches (100 millimeters). Smaller blade diameters are suitable for cutting curves and more complex shapes, while larger blade diameters are suitable for cutting rough materials with larger surface areas. Blade diameter also affects cutting depth. Therefore, before selecting an appropriate blade diameter, factors such as the material type, hardness, density, and required cutting depth should be understood.


2. What are the blade materials available?

Jigsaw blade materials are diverse and include carbon steel, high-speed steel, cobalt alloy, tungsten steel, diamond, and ceramic. Different blade materials have different performance advantages and disadvantages, such as wear resistance, strength, and corrosion resistance.

(1) Carbon steel blades

Carbon steel blades are common jigsaw blades that have the advantages of low cost and wide applicability. Carbon steel material can maintain cutting sharpness, but its durability is slightly lower than other materials.

(2) High-speed steel blades

High-speed steel blades use special materials and heat treatment to enhance their cutting performance and durability. As high-speed steel blades can cut at higher speeds, they are more common in operations that require time efficiency.

(3) Cobalt alloy blades

Cobalt alloy blades are made by alloying high-speed steel with cobalt alloys and have higher cutting hardness and longer life. These types of blades are usually used in industrial and production environments.

(4) Tungsten steel blades

Tungsten steel blades are composed of tungsten, cobalt, titanium, and other materials, have high durability, and are suitable for efficient cutting of different types of materials.

(5) Diamond blades

Diamond blades are advanced jigsaw blades used to cut various hard materials such as glass, ceramics, and stone. Diamond blades can be used for precision applications such as medicine and scientific research.

(6) Ceramic blades

Ceramic blades are a new type of jigsaw blade with extremely high hardness and wear resistance. These blades are usually used to cut harder materials such as glass and tiles.

3. What is the role of blade tooth count?


As known, the blade tooth count affects many practical aspects, such as cutting effect. If the blade has more teeth, the force distribution between each tooth will be more uniform, and the cutting process will be smoother. Additionally, a higher tooth count increases cutting speed but also increases friction and heat generation, which can cause safety hazards such as spontaneous combustion.

4. Blade shape

Jigsaw blades come in many shapes, such as T-shape, U-shape, I-shape, and L-shape. These different shapes are suitable for cutting different shapes such as curves, branches, and arcs. Users can choose the appropriate blade according to their actual cutting needs.

What should be noted when using jigsaw blades?

When using jigsaw blades, many precautions need to be taken to prevent accidents. Operators need to wear appropriate personal protective equipment, gloves, and masks, and avoid operating the saw while under the influence of alcohol. When replacing the blade, ensure that the saw is disconnected from the power source and wait for the blade to cool down to avoid injury. During cutting, avoid continuously working for long periods to prevent blade overheating, which can accelerate wear and shorten the blade's lifespan.


In conclusion

When selecting jigsaw blades, it is essential to consider which materials they will be used to cut and choose the appropriate blade material accordingly. Follow the correct usage guidelines to improve cutting efficiency and safety while avoiding accidents and equipment damage.
