Types of Shank in Jigsaw Blade
If you look for the shank of a jigsaw, you will find many of them. But a majority of the jigsaw accepts only one or other of these shank types. However, some jigsaws are available that are compatible with more than one shank type, but the majority of them accept only one.
If you are not sure about the type of shank that fits your jigsaw, you should look at the manual to find out the right one.
Two types of the shank are available in the market. T-shank and U-shank.
By looking at the shapes of these both shanks, you can quickly identify the difference between them.
The shape of the T-shank is a bit like a T. And you will find a dip at the end of a U-shank that is shaped like a U.
T-shanks are highly popular among users because they are easy to replace by simply pressing a button. Also, in modern jigsaw designs, T-shanks are used commonly.
On the other hand, U-shanks are also compatible with taking the place of T-shanks. But they lose their appeal to the users because they are slower and difficult to replace. You need to use an Allen key to replace a U-shank.
Different types of Jigsaw Blade
Different jigsaw blades are eligible in cutting different materials. While you are choosing a jigsaw blade for your DIY or any construction project, keep this note in your considerations.
Are you making a plan to cut wood-pieces using a jigsaw? Then, several options are there at your door. For construction lumber, a jigsaw blade which has sharp, large and the teeth are widely spaced, will be the most suitable.
Or if you need to do thinner cutting performance, then a small teethed, and narrowly spaced blade will become a perfect choice.
We all know that metal is a hard material and is challenging to cut. You can cut metal too using jigsaw blades which are specialized on cutting metal.
To accomplish cutting through material, you will need a sharp and tightly shaped carbon steel or alloy blade. Using this blade, you will have a new experience of cutting through metal, but it is mandatory to cut slowly and carefully.
While you are cutting materials like leather, foam or drywall, then you have no other choice to look for a specially designed dedicated jigsaw blade. These types of materials are hard to cut without doing any damage to the material, but a specially designed blade makes the task easy without causing any damage to these materials.
Material Types of Jigsaw Blades
Multiple types of materials are used to make a jigsaw blade. Every material has specific strength and weakness that you need to know before you are going to purchase a jigsaw blade.
Carbon steel jigsaw blade is the most commonly used jigsaw blade in the market. This blade is made from the combination of iron and carbon. This type of blade is lightweight and flexible enough that it can cut through softer materials without any hassle. But one drawback of this blade is, they are comparatively weak and break quickly than other types of blades. However, in terms of price, the carbon steel blade is the most affordable one.
Another type of blade is, high-speed steel blade and this one is also relatively common as a material of jigsaw blade. But they are not flexible enough because of their harder and more robust characteristics. However, these 2 characteristics make them a well-performer against harder and delicate materials.
On the other hand, if you are looking for a long-lasting and versatile type of material, go for a bi-metal blade. This blade is a combination of high carbon steel and high-speed steel that makes them highly flexible and robust.
Size & Teeth of the Blade
The cutting material will let you determine about the size of the blade you require for your project.
Also, the size of the cutting material is similarly essential. Generally, you should choose the size of the blade at least 1” longer than the thickness of the material. In maximum cases, to reduce the flexibility, longer blades are thicker. And shorter blades are thinner and more flexible than longer blades.
The teeth of a jigsaw blade do the final task which is cutting the material. The effectiveness of a jigsaw blade depends on 2 characters, size and the density of the teeth.
To get an active cut against hard materials, the TPI (teeth per inch) should be high. It is evident, high TPI blades will give you fast cutting experience and low TPI blades will be slower.
The above all point, I believe you have already realized about the answer to are jigsaw blades universal.
The real fact is, you have to choose a jigsaw blade based on your project requirement, and jigsaw blades are different in size, types and materials too. You can’t use a single jigsaw blade for all project.
Finally, the answer is, jigsaw blades are not universal.
Jigsaw can handle a variety of projects with the right blade. Before starting a project, all you need to do is, learn what type of shank your jigsaw is accepting and know what type of blade is ideal for your project.
