Different types of Jigsaw Blade, and selecting the correct one

When it comes to Jigsaw Blades, there is a huge variety of blades to choose from and a lot of them will have different features that will affect how you choose your blade. There are different types of shank, material, cut, teeth and lots more.

Shank

The Shank is the part of the blade that attaches to your tool. There are two types of shank; these are the U (Universal) shank and the T (Tang) shank. The notable difference between the two is the shape of the shank. The T shank comes out, whereas the U shank indents towards the blade. The type of shank has no effect on the performance of the blade. It just effects the install of the blade onto the tool.

T Shank

A T shank is the most common shank and it will be on the design of most modern blades. A T shank will also fit into most Jigsaws that are modern. The shank will lock into the clamp of the tool securely. A T shank blade is easy to install and requires a simple push into the tool.

U Shank

A U shank is less common; however, they are still around and popular. A U shank blade requires a screw throughout the installation process to attach the blade to the tool. This takes particularly longer than installing a T shank blade.

Please ensure to check whether your Jigsaw tool is compatible with a blade before you buy the blade.

Blade Material

The next important thing to consider with a Jigsaw blade is the material that it’s made out of. The type of material will play a big part in what materials you can actually cut through with your Jigsaw. The four types of material that Jigsaw blades are constructed out of are: High Carbon Steel (HCS), High Speed Steel (HSS), Bi-metal and Tungsten Carbide.

High Carbon Steel

This material is what a lot of low end blades are made out of. They are flexible compared to other materials, which can result in the blade changing course while cutting with it. They become worn faster, which makes them ideal for cutting materials such as wood where the task is general cutting rather than a precise cut.

High Speed Steel

These blades are significantly stronger than blades made out of High Carbon Steel. The materials characteristics are stronger than High Carbon Steel, which makes them more durable and less flexible. This means they can cut a wider range of materials such as hardwood, metal and plastics.

Bi-metal

These blades are made out of two different types of metal. The main body of the blade is manufactured out of Carbon Steel, and the teeth use High Speed Steel. This increases the balance of the blade when cutting and also increases the resistance against wear. Bi-metal blades are generally used for cutting heavy-duty materials such as hardwoods and metals.

Tungsten Carbide

These blades are very heat resistance and are the most durable type of blade. This is a result of the cutting edge being coated in Tungsten grit instead of teeth. This allows Tungsten Carbide blades to cut through ceramics, steel and fibreglass.

Teeth Per Inch (TPI)

The TPI of a blade will affect the type of cut of a blade, and will determine what the blade is best suited to cut, how fast you can cut and the quality of the cut. If a blade has a high TPI, then the result will be a smoother, slower cut. If your attempting to be precise, then you should use a blade with a high TPI. On the other hand, if you’re going for a fast, rough cut then you will be best using a blade with a low TPI. As a general guide, if you want a precise cut for hard materials such as hardwoods and metal then you will want a blade with a TPI between 14 and 36.

Plunge Cut Blades

Some blades will have a sharp tip at the end of the blade. This is so you can penetrate the material before actually beginning a cut. This is very useful if you are beginning the cut vertically against the material and from the middle of the material, rather than the edge. A plunge cut blade will be ineffective against hard materials, which makes it ideal for soft materials, softwood and plasterboard.
