How can you tell the difference between jigsaw blades?

Hailian Saw Industry has been specializing in the production of jigsaw blades for many years. There are significant differences in the shape, material, and appearance of the blades. The type of blade handle also varies. Different materials can be chosen for the blades, such as high-speed steel (HSS), bimetal, etc. In terms of tooth configuration, there are options like coarse teeth, fine teeth, variable teeth, and reverse teeth. Let's now focus on explaining the differences and distinctions in these various aspects.

1. Blade Handle Type:

Jigsaw blades typically come in two handle types: T-shank and U-shank. T-shank is the most common type with a "T" shaped handle, which is compatible with most modern jigsaws. On the other hand, U-shank blades are less common, featuring a straight-line handle, and they are typically used with older jigsaws.

2. Material Selection:

The material of the blade directly affects its performance and applicability. Common materials include high-speed steel (HSS), bimetal, and tungsten carbide (hard alloy). HSS blades are suitable for cutting non-metal materials like wood and plastic. Bimetal blades have more durable tooth tips, making them suitable for cutting both metal and non-metal composite materials. Tungsten carbide blades offer exceptional wear resistance and durability, making them ideal for cutting hard materials such as iron and ceramics.

3. Tooth Configuration:

The tooth configuration of a jigsaw blade determines its cutting effectiveness and applicable materials. Common tooth configurations include coarse teeth, fine teeth, variable teeth, and reverse teeth. Coarse teeth are suitable for fast rough cutting, while fine teeth are ideal for smooth and precise cutting. Variable teeth have different sizes, providing comprehensive cutting capabilities. Reverse teeth have their tooth tips facing backward, reducing tearing and damage during cutting.

4. Teeth Per Inch (TPI):

The number of teeth on a jigsaw blade is usually measured in Teeth Per Inch (TPI). A higher TPI indicates more teeth, suitable for fine cutting, while a lower TPI is appropriate for fast rough cutting. Choosing the right TPI depends on the desired cutting effect and material type.

5. Blade Width and Length:

The width and length of a blade also affect its cutting performance. Wider blades are typically used for rough cutting, while narrower blades are suitable for delicate cutting tasks. Blade length should be chosen based on the desired cutting depth and workspace constraints.

6. Special Blades:

There are also special design blades available for specific applications. For example, scroll blades are suitable for curved and intricate cuts, while reverse tooth blades can reduce tear-out when cutting materials from below.

In conclusion

I have provided an overview of jigsaw blade handles, material selection, tooth configuration, TPI, as well as blade width and length. Additionally, I mentioned the characteristics of special blades. Selecting the correct jigsaw blade is crucial for both work safety and cutting quality.
